review: Nikon AF-S 28mm f/1.8G lens To test out the Nikon AF-S 28mm f/1.8G (vendor), I met up with Anelisa in Brooklyn to try my hand at some environmental portraiture. With such a wide field-of-view, you inevitably have to include the background. I wanted to show the effect of the shallow depth-of-field of this lens, so I shot at f/1.8 or f/2.0 throughout. When you use a fast (i.e., wide aperture) wide-angle lens, and have sufficient distance between your subject and the background, that shallow depth of field can be used to great effect. It can be tricky though, since wide-angle lenses tend to show a lot of depth-of-field unless we’re specific in how we use them. This fast prime lens from Nikon is said to deliver superb image quality. It has the renowned Nano Crystal Coat that Nikon uses to reduce ghosting and interior flare. It also has Super Integrated Coating to enhance light transmission and color consistency. The aspheric lens elements minimize coma and other lens aberrations. From the various images I shot, the lens is sharp! Wide-open though, the contrast is reduced, and you will have to adjust for that in post-processing. Nikon’s Silent Wave Motor (SWM) delivers fast and quiet autofocus. No complaints there. The lens responded fast in auto-focusing on my Nikon D4 camera. This lens has 7 rounded blades of the lens diaphragm which is intended to smoothly render the out-of-focus areas. In other words, the bokeh is good, according to the literature. To my eye though, the backgrounds could look a little “jittery” and harsh, dependent on the background. By the way, shallow depth-of-field is not the same thing as bokeh. (Just in case you are under that impression.) All the images shown here were shot without additional light. Just the available light. camera settings: 1/500 @ f/1.8 @ 200 ISO Nikon D4; Nikon AF-S 28mm f/1.8G (vendor) The pick of a sequence of images I shot here. I love how the wind picked up her hair at this moment, with the setting sun adding just a touch of rim-light. camera settings: 1/500 @ f/2.0 @ 100 ISO Nikon D4; Nikon AF-S 28mm f/1.8G (vendor) With a sequence of photographs here with the sun directly in the frame, I wanted to check how well the lens handles flare – and it controls flare very well. The image doesn’t wash out easily. Regarding the bokeh of the lens, if you click through to the larger image, you can see the out-of-focus trees on the bottom right-hand side, has a “jittery” or wiry look to them. That’s a sign the bokeh of the lens can be harsh, and not as smooth as would be ideal. camera settings: 1/250 @ f/1.8 @ 400 ISO Nikon D4; Nikon AF-S 28mm f/1.8G (vendor) The test shots I did of the lens to see how well the edge-to-edge sharpness is (excellent, by the way), and how the distortion appears (minimal, by the way), just isn’t as interesting as a colorful image. So here it is. But really, the lens is crisply sharp. camera settings: 1/640 @ f/2.0 @ 800 ISO Nikon D4; Nikon AF-S 28mm f/1.8G (vendor) I really liked the way the light reflected off the paving in this area under the Manhattan Bridge Overpass, and I positioned Anelisa into this light. Regarding the bokeh of the lens, have a look at how it renders the out-of-focus tree on the left-hand side. (Click through to the larger image.) Again, the depth-of-field is shallow, but the bokeh isn’t entirely smooth. camera settings: 1/80 @ f/1.8 @ 1600 ISO Nikon D4; Nikon AF-S 28mm f/1.8G (vendor) Finally, a snapshot as we were waiting for something to eat at a coffee-shop in Brooklyn. As an aside, I have to reveal that Anelisa is actually a geek – the Android phone in her hand is the R2D2 model, and it squeaks and bleeps when it rings! camera settings: 1/400 @ f/2.0 @ 100 ISO Nikon D4; Nikon AF-S 28mm f/1.8G (vendor) In summary, this lens is superb! It is sharp, and an affordable entry into the realm of fast wide-angle lenses for the Nikon shooter. Also check out the review of the Nikon AF-S 85mm f/1.8G lens

Nikon je za sljedeći mjesec najavio premijeru svojeg novog objektiva dizajniranog za FX dSLR-ove AF-S Nikkor 28mm f/1.8G. Od 24. svibnja ćete moći, po cijeni od odprilike 5700 kn, kupiti novi AF-S Nikkor 28mm f/1.8G objektiv koji, kako tvrde iz Nikona, ima “savršenu ravnotežu između oštrine i bokeha”. Objektiv je ujedno i zamišljen da pokrije prazninu između 24mm i 35mm objektiva, pa je tako u 28mm žarišne duljine upakirana poboljšana optička konstrukcija koja još više uklanja neželjena izobličenja. Ovakav objektiv svakako je preporuka za svaku ozbiljnu foto torbu ili kolekciju. AF-S Nikkor 28mm f/1.8G sastoji se od 9 skupina dobro ugođenih 11 optičkih elemenata, uključujući i dvije asferične leće dizajnirane da smanje odstupanja i isprave iskrivljenja. Objektiv posjeduje sloj izrađen od nano kristala kako bi se smanjio ghosting i flare efekt. Također je opremljen i SWM (Silent Wave Motor) autofokusom za diskretno i precizno fokusiranje. Ako pak objektiv stavljate na Nikon tijelo DX formata, dobiti ćete ekvivalent žarišne duljine do 42mm. Neke od karakteristika: Žarišna duljina: 28 mm Maksimalni otvor blende: f/1.8 Minimalni otvor blende: f/16 Konstrukcija: 11 elemenata u 9 grupa (2 asferične leće i nano-kristalni sloj) Minimalna udaljenost fokusiranja: 25 cm Dimenzija filtera: 67 mm Masa: cca 330 g
