K10D/Sigma 50-500 Shoots

[brad_n]

Last week I guess I left the impression that I had too many negative thoughts

about the Sigma Bigma. Not so! I just didn't believe that it was a good

choice for the second of a lens set.

 

I was out capturing birds this weekend and here's a couple examples. All taken

with the Sigma 50-500 at f8.

I must admit I have been thinking about getting this lens for the K10d and ist I own ..

The photos composition etc are good but I dunno if it is my computer or what but you appear to have lost a lot of definition/detail in feathers and the like.. the first 2 photos have a lot of chromatic aberration which could have been PS'd out.. I get a similar problem at the top end of my sigma 70-300.. I am now considering just getting a straight 500mm but I want to see some results from it first. The photos are great just spoilt by the lack of detail/sharpness..

 

I'll hold on to my pennies for a bit longer I think

I agree with Peter, first two pictures are too soft for f8. Also I believe they have focus problem. #1 is backfocused, not sure about #2. Colors are also not vivid. #3 is much better despite obstacles, may be because it was taken at 420mm, not 500mm.

All three were manually focused.

 

How do you take CA out with PS?

The third one is a lot sharper but that will happen all the time with a lens maxed out on its high zoom end compaired to being backed off a bit. Nice shots! I just don't know about the clarity of the lens at 500mm
