can set up all your lenses, you're stuck calibrating only one lens I
guess - which may or may not be such a good idea, depending upon what it does to your other lenses.


Is it realistic to send Canon my 40D and 3 or 4 different
lenses, ask them to test all of them and then what? There's bound to be
competing interests amongst the 4 lenses - the 50 1.4 needs a +0.3, the
17-40 wants a -0.2...


Lucky for me that I enjoy MF. AF takes half the fun out of shooting so I really don't mind, but it is a little disappointing...

One more (dramatic) question, if you guys don't mind playing along...


Here's the stakes - if someone can focus better manually and get a crisper shot, you are instantly beheaded.


If you had to nail focus - it was a matter of life or death -
and you were shooting hand held, no Live View, plenty of light - would you feel totally
confident using your cam's AF?


Would you AF in low light as well? (same stakes apply!)


Thanks for your input everyone - I really appreciate it.
