well when you know what your doing you try to keep your ISO as low as possible.
sure most consumers and soccer moms will not keep such a close eye on the ISO setting.
in my small home studio i always shoot at ISO 100.
i have plenty of light so why should i go higher.
when doing nature and wildlife i try too keep the ISO as low as possible.
i never use auto ISO.
only time when i use auto ISO is is when i do city traveling.
then light changes often so fast, inside outside, shadows of buildings etc. that auto ISO is a help.
I have to disagree with this to an extent. I don't use auto ISO incidentally, as I find it too unpredictable, and I like control over all the settings. But I have gradually learned that shooting at higher ISOs is often better for some subjects. I shoot a lot of birds, and it's much better to get a slightly overexposed shot with no motion blur, that can be darkened in postprocessing, than either have a dark image that you have to brighten, or one where you've used too long an exposure (which with birds and long lenses is anything under 1/250 in my experience). I used to try and keep the ISO as low as possible, but exposing to the right is often better (and this involves higher ISO because there's often nothing you can do about aperture or exposure time in this situation).
Incidentally, I rarely shoot at base ISO. Even in good light, my bird shots require 800, and given the low light I usually contend with, 3200 is probably commonest.
And as a general point (returning to the original theme of the thread), I feel like there are three broad camps of people who complain on this forum. People who have the 7D and want a newer version; people who like mirrorless and want a robust option from Canon; and people who would moan whatever - who dislike Canon, who have unrealistic expectations, and don't understand the reality of business or technology - and the compromises they entail.
I got a 5DIII, so I'm still happy with them. I understand the 7D crowd's impatience, but as for the rest... nobody is forcing you to choose Canon. If you like other companies' offerings, and aren't tied to a bunch of lenses, go with them. Not every company has to do everything all the time.
Innocent that I am, I think I didn't expect a Canon forum to be so full of relentlessly anti-Canon sentiment.
