I have to agree with Roy, you should try birding with that lens again on your tripod. Several of the pics are a little soft but it is probably asking for too much for SR to fully compensate at 500mm. I would love to see some tripod shots to compare.

The birds are wonderful , great colours.

I find on my Sigma 70-300mm that the 'sweet spot' is between 190-220mm for the sharpest shots.
I have read that most lens do have a 'sweet spot'

Pusher...We did not get that way with out posting or sharing our photos and letting others comment and give suggestions in how to make them better. You need to post them every chance you get...I usually get blasted for posting too many but that is how I learn...from doing and listening to the comments and critiques! Just have to remember to not get upset when what you thought was a hummdinger of a photo to you turns out to be a flat pancake to others! LOL Even there , there is an opportunity to learn!

for HH you did pretty good but i think you really need a tripod. were these shot wide open?? what are the specs on the lens.
I have a tripod but it is one I bought to use with my DX6490 Kodak and is not really that great a tripod for this heavy a lens. I plan on doing some more of these but must wait till the weekend to get that late afternoon light as I work a second shift and Sundays are the only days I get off...if then... The Samyang 100-500 has a 72mm lens opening and is a 1:5.6-7.1 aperture.

Thanks for the comments...This one may have that sweet spot but it will take me a little while to find it as the learning curve on the camera and playing with all the Ebay lenses is taking so much of my free time! I will see where it is this week end maybe.

thnaks for the exif. this lens appears to have a lot of potential. for a cheaper model it seems to do very good wide open. the reason i mentioned tripod is that all of these except #1 seem to have some movement in them. also i'm sure this lens will preform much better at f8-11. i don't know what you paid for it but i think it is well worth it.
