Relief !
I wouldn,t say that saturdays trip to Leighton Moss was a disaster, afterall I got some great Robin pictures and met a new contact Steve. However it did nothing to assure me that my camera was working OK after its fall. 

I went through all the settings and put them back to the ones that have been sucessful for me in the past. I also got some great advice from Jeff (the black fox) and Bob (BobT18). I took their advice and manually set exposure (f8) and shutter speed (800) and used  ISO to adjust for lighting conditions. I now know that the sigma has a sweet spot at f8. 

I went to the local pond and fired off some frames at the resident ducks and gulls. About 90% of the images were perfectly sharp like the duck above. I think this is proof that the camera survived its fall which is quite impressive. 

Thanks to Jeff and Bob.......
