If you dont have to do extensive cropping (more than 50%) you are not underexposed, and you know your way around noise reduction, iso1600 is very good, and even 3200 is good. this is one that is about iso 3200 http://farm7.staticflickr.com/6199/6138887805_9933de181f_b.jpg
Amazing bird images posted here....clearly a great mix of talent and gear!!
Can any 7D users comment on the IQ at ISO 10 - 200? Would it be better or are higher settings better on the 7D? Asking because I'm thinking 7D or 1D3 at the moment....my upgrade from a 40D.

The ISO 100 through ISO 400 images are superb, and even ISO 800 is very clean. I try to shoot at the lowest ISO setting that will give a well-exposed image, because the less amplification applied the higher the signal-to-noise ratio and the cleaner the image, but except in strong shadow areas I can barely notice any difference in image quality between ISO 50 & 100, or between 200 & 400.
In informal testing I actually found ISO 160 to be the best, and 320 to be marginally better than either 200 or 400, so those are the two setting I use unless something else is absolutely needed.
with every camera, the lower the ISO the better. I can tell the difference between iso 200 and 100 on 7D at 100% before noise reduction. that much said, it is very usuable to 1600, and even at 3200, but have to be more careful with selective noise reduction.
there was a very good article from a birder, comparing the detail produced by the 7D and 1d3, and found even though 7d has slightly more noise per pixel at a given iso, it produces more detail. some say 7D has the second best autofocus in canon lineup (behind 1d4). many say a properly funcitoning 1d3 or even a 1d2 i better.
Now why didn't I think of that?
