Occasional bird snapper
This morning I have been playing around with auto iso for the first time ever on my 7D. I was using AV mode f5.6 and evaluative metering ( + 1/3 ev). The shutter speeds I am getting are between 1/640 and 1/800 which is ideal for hand-holding my 300/2.8 + 1.4 tc with I.S. on. How does this work? is the shutter speed relative to the focal length of the lens you are using?
First results are encouraging and it could be useful in variable light situations I guess. I am a bit concerned about the intermediate ISO being used as they can apparently result in more noise than the next full ISO up according to what I have read. Having said that I have noticed lately that a lot of top shooters seem to readily use intermediate ISO - how much of a problem is this on the 7D in your experience?
