Ornito Photography with Pentax

This has been n issue among Turkish Pentaxians since long time. I know some Pentaxians changed to Canon because of Ornito Photography. I wonder whether K-5 will be an naswer for this question. This afternoon I've heard a bird singing in my garden. This reminded me this question and I urged to get my new K-5 in my hand. First thing what I can say is about AF peformance. I can say Af performance will be anough for ornito photography. I made shots with different ISO levels to test high ISO levels. Here are the results for your intervention ;

By the way is there anybody who can tell me the species of this bird?

F/6.7, shutter speed 1/640, ISO 200, Focal Lenght 500mm



F/9 , shutter speed 1/8000 , ISO 3200, Focal Lenght 500mm


F/11 , shutter speed 1/8000 , ISO 6400, Focal Lenght 500mm

No I only made small adjustment on contrast and brightness

Did you use the Sigma 50-500mm for these shots, I couldn't help notice the bad purple fringeing especially on the first shot.
The bird is a Robin, as seen on Xmas cards.

Yes it is Bigma 50-500mm. When you draw my attention I've paid attention to the purple fringeing as well. I think the reason of fringeing is the direction of the light which is coming behind the object. The lights direction was not very good and I did not have better position to shoot accroding to light and object. Anyhow, I'll desaturate the fringeing with sponge tool of PS. Thanks for giving species data.

Ornithology is the branch of science that deals with birds. Photography that focuses on birds is also called ornitho photography.

as said abovem a Robin but as the Americans use the name Robin for another species of bird (can't they adapt??) you may add "european". Or you could call the other one "American Robin":
Robin

I think that by K-5 its better to stop down 1EV you will be able to fill light in dark areas but purple firing will be much less visible.
Purple Siring its also produced by in lens reflectin. when area is over exposed the reflections are more visible ( they get more light also.

You're right Piotr but the difficult thing in Ornitho Photo is the speed. After exploring where the bird is really there are few seconds to shoot before losing the bird in sight. But I'll keep yur advise in mind the next time to give +1 ev step if I'll have enough time to do so. Thanks a lot.

Robin
If you leave it to the Americans there will only be one type of robin
Even in 17 Cherry Tree Lane London

BTW are other users noticing higher Purple Fringing with the K-5?
