I seem to have had a hard time with getting the exposures right and not sure if it was me or the lens or the light conditions, any suggestions of course appreciated. I will also say if you are thinking of buying this lens also by a packing mule, is heavy and awkward to carry around esp with all other equipment.

Thanks for getting this up...that was fast!
It maybe clunky but takes nice shots.
Up close and personal. They are are very good.
[her4.jpg] My favorite. I think the exposure is about a perfect as you could get with the lighting. Focus is awesome.

Ellamay you just need a husband,boyfriend or mule!

This is the strange thing about using the lens @500mm. You know that aperture isn't bigger than f/6.3, but (as EddyG has researched/suspected) the lens is lying to your camera (and perhaps it's doing it across the entire zoom range). If you're shooting RAW you can expose a little more to the right than usual (maybe 1/2 to full stop); otherwise, compensate by 1/3 or 1/2 stop.

I assume you shot with tripod, but are you using a cable release (or timer) as well? I know you don't get mlu with the 300d, but you might be able to increase sharpness a little like that.

Also, did you do (much) post-processing on the shots?

I am a little a confused by what you are saying, nor do I really get why it matters. Do you mean that when shooting I should increase the exposure compensation to make up for it? Would that 'fix' the lack of light?
And I did use tripod, sometimes clicking my self and some shots I used timer. Definately need to be steady. I did nt do much post processing but I did sharpen them some, same amounts I do all my shots at, 90% before resize and 90-110 after resizing. It was quite a bright day and I suspect that helped them to be sharper, some taken in more shady spots were not as sharp.

If I get a chance, I'll do some additional tests and report back.

i'm impressed by the quality. And even if you didnt choose it, the backlighting conditions are actually visually appealing, adding 'glow' to the translucents parts of the animal, rimlighting its feathers, etc.
