when you change lens do you...

hold down the hold down "lens release button" just to initially release lens (as i do) or do you hold it down thru the entire unscrewing process of attached lens?

Never really thought about it that much but I hold it down till the lens is off. Not sure why, just habit I guess.

Till lens is off.....

Both, I suppose. Never really thought about it before, though.

Just initially.
There is no need to hold it pressed all the time till the lens is off.

I usually just hold it down just to initially release the lense and twist the lens off about half way; I then grab the other lens so that its ready to be put on as soon as the first one comes off.

i never gave it much thought either but i was in a somewhat hard situation (i had to be a contortionist) to change lens early this am and i realized i had let the button go as soon i had started to spin lens free and just wondered what others do and since i never looked at whatever the heck part the button releases i have no idea if it would cause any wear on part or any issues.

obviously if users have done what i did and have had no ill effects i have nothing to worry about.

and thanx for the prompt responses

Till lens is off...it just helps me maintain a secure grip while the camera is pointed down to avoid dust during a lens change.

Only to unlock I think.

chevysales,
Just to unlock the lens, I found this out a long time ago with my 10D when trying to get it off this lens

hrm....for me..hold down button all the way through

If holding it pressed all the way was required, I’m sure that Canon would say so in their instruction manuals…

You are probably correct but the question was what do we do..........

I agree, but questions about What we do are often tightly connected to questions of Why we do that – and hence my comment.

Just slightly expanding the subject, that's all..

Both I suppose, I never pay any attention to it so I suppose that when using both hands it may be held down while I twist the lens all the way. I am more frequently switching one handed though, so the hand around the lens barrel is also pushing the button with a finger tip, so I release as soon as the barrel starts turning, as my finger turns with it!

I've never thought about it before and really couldn't care less which way I do it, It's just a locking mechanism release so it doesn't have any effect once the barrel starts moving.
