1D autofocus

I have discovered on my 1D that if I use only the shutter button to focus and take the exposure the autofocus is very much faster. I have been using the back button for about a month and just switched back on Saturday to the shutter button only and it worked far better.

Old news or just pure strange?

i dont know if the focus should be faster, but ive always found that my personal reponce time is better with the shutter button, and have never used the * button for focusing.

I always focus with the back button and dont see any change in speed.

Me too.

ever since I started using (*) button to autofocus I've been having wrist problems...carpal tunnel like symptoms

In a strange turn of events - my wife left me since I started using the (*) button for focusing.....

Intresting i think i will give that a go

I do both ways. I don't really notice a difference. I'd say the biggest difference for me, is the once in a blue moon hitting the shutter all the way down. Pre-mature shutteritis.

Both ways are valueable, depending on the situation. I like having the option of being able to use both ways.

Same here...

I use CF4-1 maybe it will slow up a bit when using CF4-3

Probably becuase you have to fully press the back button in relation to the shutter button which is far more sensitive to a mid way execution to focus

There wont be any AF speed difference. Just the command delay
