- Objavljeno 23. - Kategorije - Tagovi - Denis Jeleć Nokia 808 PureView – pixels are more than (ir)relevant Not that long ago, Nokia managed to shake the mobile world industry with the announcement of the 808 PureView, camera phone like no other. How else to describe a device that serves as more than a capable smartphone and which includes camera tech out of this world? No, seriously; Innovation that lead to this piece actually has its origins from satellite imagery and has roots where else but with Nokia N8. Some reviews are better started off in a grandiose manner. So let us shoot that out of the way and say that the Nokia 808 presents the most revolutionary mobile device unveiled this year. Of course, such title is mostly related to its imaging ability. While the very unveiling managed to completely outshine everything else at the Mobile World Congress 2012, what are the impressions that follow few weeks of usage as a daily driver? Approach one, hardware has landed So, here it is, contrary to all the ongoing trends of making devices thinner and yet larger in screen size, as well as stuffing of the components once thought will never show up in mobile devices, alone stands the 808 unit. It has no myriad of CPU cores, it has no tons of RAM, and it has no screen resolution that surpasses most displays on our desktops. This chubby (even name fits it!), yet adorable device resists all of the industrially pushed factors. At a glance, it seems cumbersome, jarring and inconspicuous at the same time. A deceiving glance. Quite a few articles about this smartphone can be found on our pages (in Croatian language, mind you), but this marked the first time we have put our paws on it for a proper review. To start things off, a brief hardware overview; Nokia 808 PureView is powered by 1.3GHz ARM 11 processor with Broadcom BCM2763 processor dedicated to graphics and multimedia. It is equipped with 512MB of RAM and 16GB of internal storage (+1GB of ROM). Latter is expandable with microSD cards found under the back cover. Li-ion battery has a capacity of 1400mAh, and in order to make everything tick from the software side there is Nokia Belle operating system. Oh yes, we almost forgot…there is this tiny detail, a brutal 1/1.2” sensor containing oh-all-sweet 41MP’s. Just to put its size into perspective for this brief introduction, mobile phone sensors are tiny in comparison, and this beast puts a shadow over many high-end compact cameras around. Wide angle Carl Zeiss optics has an integrated physical ND filter, but we will come back with more details later in the review. Minimalistic and industrial design of the device is available in three colours (red, white and black), and each and every millimetre of the case breathes of outstanding, practically impeccable build quality. With its 169 grams, 808 is found to be somewhat on the heavier side, but neither that nor thickness do not make it uncomfortable to hold…au contraire. Peculiar and ergonomic curves of the coarse(r) textured, matte polycarbonate shell that surrounds the Gorilla glass covered front enable a simply outstanding grip. One may go as far as to say that it is actually a great joy to use compared to many of the competing smartphones which are considerably thinner – yet all together failing at the ergonomics class. Even the hump where the camera optics and sensor lie is ergonomic – along with textured surface, it prevents the phone from slipping downwards when held in one hand. Left side of the device is completely void of details, unlike the right side: multifunctional up/down buttons, slider for (un)locking and the two stage camera shutter button. Bottom of the device is covered with two holes; one for the high quality microphone and another for the strap. Top has a USB and HDMI ports as well as another high quality microphone and a 3.5mm audio jack. Back contains plethora of features. Hump contains optics, a xenon and LED flashlights, a powerful speaker, while under the back cover itself an NFC antenna is built in. Front is covered with one piece of Gorilla glass with openings for earpiece and three buttons further down the screen. Behind the polarizing protective glass layer, numerous sensors as well as 0.3MP camera are hidden away. As noted, grip is amazingly good for such a chubby device. Design applied simply does not have any flaws, and every single aspect is seen as carefully thought out before manufacturing – something that should give competition a clue or two what they ought to do instead of dealing with appearance only. Details go all the way down; even the lower part of the back cover contains a grip strip that makes holding the device oh-that-tiny-bit easier and secure while snapping photos or recording high quality video. Viewing content is easier thanks 4” CBD AMOLED screen. Where it lacks in resolution (360×640) it more than makes up with quality; during daytime, it is perfectly visible in all conditions, and although “pixel peepers” might notice the lower resolution in close-face encounters with the device, image quality is fantastic. Sharp, rich and eye catching. Decision to not use the PenTile matrix in 808 PureView was certainly a wise one. Thus, PureView was conceived Nokia has been developing the PureView technology for full five years. They went from countless ideas of incorporating optical zoom, and they realized it is not worth it. Fragility, space such optics occupied, etc. was simply deemed unworthy of building. Then, one of the researchers realized they might use something that the satellites use when capturing photos – high resolution imagery that can be “zoomed” in and oversampled using special algorithms in order to get a more pure image, devoid of noise, bad pixels and aberrations. So a 41MP 1/1.2” sensor was born; with an active surface area of 7728×5368 pixels, it is something never seen before. Such resolution required incredible optics as well, and even that came to be in five years of development. Nokia and Carl Zeiss have managed to stuff the device with f/2.4 optics that contains five aspherical elements in one group, Neutral Density (ND) filter and a mechanic shutter. 35mm equivalent of Zeiss’s 8.02 mm focal length is either 26 or 28mm, dependant on whether user snaps in 16:9 or 4:3 format. Nevertheless, as even Nokia claims – pixels themselves do not matter. It is what’s done with them that matters the most. Although the full resolution samples give out brilliant colour reproduction, low noise levels and solid dynamic range, oversampling mentioned earlier is what gives 808 PureView supreme performance. Photos taken with PureView mode on are oversampled to 3, 5 or 8MP in size keeping the best pixels from the fullsized image. All that is done in an very short amount of time, and helped out with a dedicated imaging processor. PureView technology is not only used for photos, but for videos as well. Even while recording the high quality 1080p video at 30fps, device is able to use the whole sensor to enable user to zoom a bit without any loss of quality. Even at this highest setting and therefore lowest zoom available, it is perfectly possible to record macro level documentaries: In regards to the sound, Nokia’s Rich Recording Stereo is nothing short of astonishing. That is an accompanying technology to PureView, and Damian Dinning of Nokia called it a sui generis HDR version of the sound. Such tonal range is expected only from the more expensive and dedicated cameras; there are no distortions whatsoever while getting the incredibly rich sound all the way up to 140dB. That alone makes the device perfectly capable of recording concerts and live events. Next video is best listened (not watched as sequences are somewhat depressing) with a pair of high quality headphones: In case you were wondering, general quality of the video is superb. In addition of a tripod, Nokia 808 PureView becomes a fully capable professional recording unit, and competition in the mobile world simply doesn’t exist. 38MP is brilliance, and yet one needs only 5 Initial comparison was performed with the following main roles: iPhone 4, compact prosumer camera Minolta A1, and of course, 808 PureView. It was most unfortunate not being able to test it against 8MP units which were not available at the time of review. In the previous testing I’ve done (conflict of fifteen megapixels – Croatian language) it was clear that practically most mobile cameras show their true (and bad) face while compared to a measly compact camera that earned the title blast from the past. So, curiosity was high and testing under 5MP PureView mode began. Location: TV Tower in Stockholm. Elements of surprise: heavy rain any moment. Results are quite clear from 100% crops of the photos (click for higher resolution) and there is no need to dive into paragraphs of interpretations. In the example to follow, Minolta A1 tried to expose the scene properly although that lead to a few overexposed areas, while iPhone continued to plague the image colours and white balance. When it comes to noise performance, 808 has none in practically all of the test photos. Counter-light setup was challenging for all three devices. The success of light measurement and exposure is visible in the next test comparison: Even a glance at 100% crops shows all of the power that oversampling has. As stated before, 8MP devices were unavailable for the test, but…what happens when one decides to mount the DSLR unit on a tripod with appropriate wide angle lens? You get a surprise. As 808 PureView lacks the ability to oversample images automatically to 12MP, test photo was done on a tripod and manually oversampled to fit image dimensions that Canon 5D produced. What you can see in crops is not a trick. There is no photo editing whatsoever, and both devices fired in auto mode. 808 managed to provide more details in every single part of test photo; be it sprocket in the background, be it blade of grass above the plastic shovel, be it holes on the cardboard box or fibres on the broom. One has a most difficult time trying to figure out the fitting epithets to use for image quality on 808 PureView. Even compared to some Canon full frame monsters with L-class lenses attached. Oh the blasphemy. Perhaps. Perhaps not. The matter is quite simple, really – in some conditions PureView can outperform anything. That is all. Ol’ madame Belle A colleague Jerko Cilas earlier gave a lookaround on Nokia Belle (Croatian text), and regardless of some updates that came in the meantime, not much has changed. Nevertheless, it is worth adding a few words. In expectation of a heavy-footed operating system that is controversial even today, first startup was really a delightful experience. User controls are fairly intuitive, although there is a brief period of adaptation to them. Icons, widgets, notification system…all is there. Moving from one home screen to the next and practically every operation on the device itself seem rather fluid. Much more fluid than one might expect. However, there are some things that simply belong to the past that irk and annoy the user and must be taken off the back immediately; app installation seems to last for an eternity, and although it is done in the background, some of the applications even ask for a device restart (!?). App store seems to be in quite a messy state, and it was impossible to find a Skype available for Belle. Browser is horrid. Some of the colleagues complained about the speed of rendering the page initially while I have an opposite grudge. I hate the behaviour on screen after the site is loaded, and the whole experience reminds one of the old days of equally horrible Internet Explorer Mobile on Windows Mobile. To call it slow would be an understatement, during listing, during pinch-to-zoom, during…everything. Even the installation of the Opera browser did not put a smile on my face, as the problems remained the same. To put the nail in the coffin of this rant, 808 froze completely on couple of occasions and the only solution was to remove the rubber casing, then the back cover and then the battery. Until an update for bugs like these is available, average user might become quite irritated. All is not grey in the Symbian land, fortunately. It is an truly powerful system, that has as many features as one may think of – and all of that with included brilliant battery life. The latter is possible only if the user isn’t too prone to snap pictures for half a day, as the camera is exactly the component drinking most of the energy juice. Getting a portable charger accessory may be a good idea for photographers… Using the camera in a more normal fashion, device can run on a single battery charge for a full day or two without major problems. Belle is brilliant at managing system resources without any input from the user (to close apps etc.). Regarding multimedia, we once again return to the power of the dedicated imaging processor. Zooming in full sized images on the device is a breeze, and fluidity does not stop while listing the whole gallery for a while to load images. Audio reproduction is as good as its recording. Powerful speaker unit makes good quality ringtones a must have, but 808 shines in the true light only after a pair of high quality headphones or speakers are plugged in. Moving through albums and pretty much everything related to the music is simple and good. Not excellent, though as the lack of media controls on the screen can be somewhat distracting. It is a necessity, no matter how much someone can name it as being spoiled. Any fullHD video content is happily swallowed by the chubby (regardless if it is on microSD card or internal memory) – and there is no visible lag during reproduction. Promising future of the development Nokia 808 PureView is truly a magnificent device, the very best that the world of mobile image capturing has to offer (and even beyond). Overall impression is somewhat impaired by the used operating system which is, although polished a number of times, still a relic of the past. Using it on a daily basis occasionally resembles using long forgotten Windows Mobile, and even (earlier) Android versions. Features, on the other hand, are numerous. Worth of special noting is definitely the integrated complete navigation solution from Nokia. It works like a charm and has never failed during the test. Despite the bad points, before anyone steps up to claim the whole device is not worth getting just due to the operating system used, one must remember that the sole operating system is not the product. Product is the device in its entirety, and that entirety is more than acceptable for many users. Overall, let us just say that Nokia 808 PureView does not hide the fact that it is punching its way through primarily to niche of users, especially ones that appreciate the saying that the best camera is the one you have with you – not the one you left at home. The other thing for closure is that the 808 PureView is a sui generis testbed for technology that is being continually developed somewhere in Nokia’s labs. If we are to believe the words of their folks, we will not wait for the Windows Phone variant for too long which is a comforting thing for those who are most impatient. It is already clear that I will miss the review unit I have gotten, regardless of occasions when it was somewhat of an annoyance to use. Compact camera was the thing 808 successfully put on the lower shelf to collect the crew of the dust bunnies, and the whole oeuvre of the operating system certainly has something to offer, with a fair dose of compromise. Naming the whole device an unsuitable one just for that would be a grave error. Some photos are accessible in full resolution on the link Accessory overload Although the entire device seems robust with almost tank-like build quality, rubber casing accessory available for purchase is a desirable one for couple of reasons. Dust, scratches and impact sensitivity is significantly reduced, while already mentioned default robustness is further reinforced. Although the shell of the device is completely hidden by a piece of not so attractive rubber, it is easily detachable and removable. Camera casing (or the hump) is the most fragile component of the 808 PureView, and as such, it has a detachable cover that is always strapped onto the rubber case. This protective cap is quite useful, as the device is often laid down on the back when not in use – and the hump with optics is the thing protruding the most. The only uncovered part of the phone is the slider (un)locker, everything else is encased with rubber. While one may think that it reduces the manageability of the device and sensitivity of the buttons, that is not the case. Even the two-stage shutter button works splendid under it. Aside from protecting the device from falls and scratches, rubber case is important for the front. Although it does not cover it, it creates a few millimetres of distance between the glass and the surface – particularly convenient if user tends to “park” the device onto tables facing downwards. Next in the line of accessories is the HDMI cable/adapter that, aside from making the 808 easily connectable to TV screen and alike, is not anything out of the world of ordinary. It is wrapped in a rubber casing, clearly intended for often usage and reduction of a chance to harm the cable itself. One of the most interesting and useful accessories is the portable charger. Photographers are going to like this one. A lot. It has a capacity of 2200mAh and is chargeable with a usual Nokia charger or through a USB port of a computer. On one side there is a set of four LED charge indicators which power up during charging or when button is pressed. This colourful stick comes with the appropriately coloured cable, and with such practical design and usage scenarios, it is surely an accessory to have in both photo bag and even purse. Having a USB connector to supply fresh juice for power hungry devices, it can charge the whole variety of them – not only 808 PureView. Finally, it is possible to get a spider tripod and special Nokia attachment for tripods. It works rather well with 808 PureView, but thanks to the adaptable rubber grip one can fit most of the mobile devices with ease. Bear in mind it is not intended for (+)5” giants, although they might fit somehow.

- Objavljeno 30. 06. 2012. - Kategorije - Tagovi - Denis Jeleć Upoznajte se s mobitelom Nokia 808 PureView i svim njenim dodacima Nokia je nedavno na hrvatskom tržištu predstavila i objavila dostupnost uređaja 808 PureView, kameru koja ima i mogućnosti pametnog telefona. Kako drugačije opisati nešto što daje nevjerojatne fotografije? Bilo kako bilo, u rukama je daleko na sjeveru kontinenta, a ovo je prvi pogled na hardver, kao i kratka recenzija dodataka koje je moguće nabaviti za 808 PureView. Već je dosta riječi prošlo Gadgeterijom o ovom fotoaparatu pametnom telefonu, no ovo je prvi put da je uređaj u šapama za recenziranje. Za početak slijedi kratki pregled hardvera; Nokia 808 PureView je pogonjena 1.3 GHz ARM 11 procesorom uz Broadcom BCM2763 procesor zadužen za grafiku i multimediju. Opremljena je s 512MB radne memorije i 16GB (+1GB ROM) interne memorije, a uz to ju je moguće proširiti i microSD karticom. Clear Black Display je AMOLED ekran s polarizatorom dijagonale 4″ i razlučivosti 360×640 piksela. Li-ion baterija je kapaciteta 1400mAh, a kako bi sve funkcioniralo sa softverske strane tu je Nokia Belle OS. Ah da, tu je i brutalan 41MP senzor veličine 1/1.2″ (s mobilnim uređajima je neusporediv, a veći je od praktički svakog kompakta na tržištu te u rangu s nekim kamerama mnogo viših klasa) sa Carl Zeiss optikom u koju je integriran i ND filter. Nokia 808 PureView ne krije kako je riječ o uređaju zanimljivom tek niši korisnika, a posebno onih koji vole imati mogućnost okidanja visokokvalitetnih fotografija iz džepa. Uređaj je dostupan u više boja minimalistički dizajniranog kućišta (crna, bijela i crvena), a svaki milimetar na njemu odiše besprijekornom kvalitetom. U rukama je uz svojih 169 grama Nokia 808 PureView nešto teža, kao i nešto deblja od ostatka društva pametnih telefona, no u uporabi to niti najmanje ne smeta. Zanimljive i ergonomične krivulje hrapavog polikarbonata koji zahvaća kompletan uređaj sem prednjeg dijela na kojem leži Gorilla staklo omogućuju fantastičan grip, mnogo bolji no što to pruža većina konkurencije. Na dizajn doista ne može biti upućena niti jedna jedina zamjerka, čak ni na grbu u vrhu ispod koje se uredno smjeste korisnikovi prsti prigodom upravljanja uređajem, istovremeno onemogućujući klizanje iz ruku. Deblji dio uređaja je upravo ta izbočina s gornje strane koja u sebi krije enormni senzor i optiku. Nokia i Carl Zeiss su, usput rečeno, u ovu grbu uspjeli upakirati f/2.4 optiku koja se sastoji od pet asferičnih elemenata u jednoj grupi, ND (neutral density) filter i mehanički okidač. 35mm ekvivalent Zeissovih 8.02mm žarišne duljine iznosi 26mm ili 28mm, ovisno o tome snima li se u 16:9 ili 4:3 formatu. Lijevi bok uređaja krasi praznina dok je desna sušta suprotnost: višefunkcionalna gore/dolje dugmad, klizač za zaključavanje i otključavanje uređaja te okidač (s dva stupnja) za kameru. Donji dio uređaja krije jednan od mikrofona te rupicu za vezice, a na gornjem se osim drugog mikrofona nalaze USB i HDMI utori uz 3.5mm audio priključak. Straga je tu tek kućište kamerice u kojem se, uz naravno optiku, nalazi i LED svjetlo te punokrvna ksenonska bljeskalica. Prednji dio je praktički jedan veliki komad stakla sa otvorom za zvučnik i tri tipke spojene u jedan komad plastike u dnu. Iza polarizatorskog stakla se još nalaze senzori i 0.3 MP kamerica za video pozive. Iako cijeli uređaj djeluje iznimno robusno, gotovo tenkovski građen, gumena navlaka koju je moguće nabaviti za njega je poželjna stvar iz više razloga. Prašina, udarci i ogrebotine bi trebali svedeni na apsolutni minimum, a navedena robusnost je samo dodatno pojačana. Iako je kućište potpuno sakriveno od pogleda naizgled neuglednim komadom gume, moguće ju je vrlo lako i montirati i ukloniti po potrebi. Kućište kamere, najosjetljiviji dio modela 808 PureView, je zaštićeno posebnom kapicom koja je za glavni dio gume uvijek pričvršćena vezicom. Kapica služi kako bi zadržala prašinu podalje od optike, ali i grube podloge – jer se mobitel nerijetko stavlja tom stranom na dolje, a grba je ipak najizraženiji dio. Dugmad s boka je prekrivena gumiranim varijantama koje ne umanjuju osjetljivost, čak ni kod dugmeta za okidanje (gdje je najbitnija zbog dva stupnja pritiska). Jedini “goli” dio uređaja predstavljaju priključci s gornje strane i klizač za otključavanje. Osim što koliko-toliko uređaj štiti od padova i ogrebotina, gumeni pokrov je posebno bitan za prednji dio stakla koji je montiranjem zaštite milimetar dva udaljen od podloge. Posebno zgodno ako korisnik voli uređaj “parkirati” baš na tu stranu. Sljedeći u nizu dodataka jest HDMI kabel/adapter, koji, osim što omogućuje lakše povezivanje 808 PureView sa televizorom ili nečim sličnim nije ništa naročito. Nalazi se u kućištu od gume, očito prilagođenom češćem prenošenju i smanjenju šanse za oštećivanjem kabla. Jedan od posebno zanimljivih dodataka jest prenosiva baterija/punjač. Fotografima će ovo biti od velikog značaja ako provode kompletan dan u odrađivanju posla, ali i svakom drugom tko maksimalno koristi uređaj. Kapaciteta 2200mAh, štapić dostupan u više boja se puni putem standardnog Nokia punjača ili preko USB priključka na kakvom računalu. Na strani gdje se puni nalaze se četiri LED indikatora napunjenosti uz dugme za njihovu aktivaciju, a dolazi uz USB kabel iste boje. Praktičnog dizajna lako pronalazi svoje mjesto bilo u foto torbi ili ženskoj torbici – potpuno je nebitno, a njime je moguće solidno brzo puniti praktički sve uređaje s micro USB priključkom. Konačno, moguće je kupiti i hobotnica stativ ili tek minijaturni Nokia priključak za foto stativ koji omogućuje stabiliziranje slike i postavljanje u bolje položaje. Posebno dobro funkcionira s 808 PureView, ali je zahvaljujući gumenim gripovima i prilagodljivom visinom moguće ubaciti bilo koji smartphone koliko-toliko normalnih dimenzija. Upravo zahvaljujući prilagodljivosti on će biti korišten u fototestovima za konačnu recenziju uređaja Nokia 808 PureView. Vrijedi spomenuti da je grip još solidniji kada se 808-ica nalazi u gumiranoj zaštiti, a naivnog promatrača izgledom lako može zabuniti za kakav kompaktni fotoaparat. Tehnologija koja leži iza kompletnog rješenja za foto trenutke je razvijana preko pet godina u Nokia laboratorijima. Upravo stoga neće biti teško sačekati još koji dan, kada bi oni gladni čitave hrpe foto i video primjeraka s analizama trebali doći na svoje u punoj recenziji. Do čitanja! Dok čekate, pročitajte sve što smo do sada saznali o Nokiji 808 PureView.
