If you dont have to do extensive cropping (more than 50%) you are not underexposed, and you know your way around noise reduction, iso 1600 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?
