Just picked up a Canon 70-200 F4L and when mounting the lens, it goes about half way, then I get quite a bit of resistance, then it continues on and clicks into the mount.

Is this normal on the L lenses? I have read about some of these issues in the past, and it ranges from, "there's no problems" to "its normal , don't worry about it"

The camera having the issue is a Canon 550D or T2i... I have other L lenses that are quite easy to mount, so I know its not the camera.

There are no burrs, or bends in the collar of the 70-200, but there is a little plug that seems to be sticking out... not sure if that's supposed to move or not(like a plunger), but it does not move.

any info would be appreciated!

I think its normal. My 70-200 F4/L does the same on my T3i/600 D body.

Maybe its associated with the lens lenght/weight?

As long as its secured, properly mounted and everything is working you shouldnt worry :cool:

It sounds like you cannot find any other examples of this being a problem either. To be honest, your description sounds precisely how any Canon lens would be mounted: starts easy, then a little resistance until it "clicks" into place. I do not think that there is any problem here at all.

This is utterly odd ... just got a 17-40 F4/L today and mounting the lens feels exactly as OP states. Not the same feel with EF-S lens nor vintage lenses :confused:

Both of these lenses are weather sealed, right? That means they both have a rubber gasket near the mounting area, right? Rubber on metal would create more friction than metal on metal. It's just the weather sealed mount, guys, no worries.

The 17-40 F4/L has weather sealing. The 70-200 F4/L doesnt.

Oh, gotcha. Thought he was talking about the 70-200 f4 IS.
