Owners of 70-200mm L IS II - lens body movement when connected to camera body?

<p>Hi folks,</p>

<p>I have a 1Ds MKIII and am a proud owner of a brand new EF70-200L ISII lens. I purchased it from an authorized big box retailer so I am not worried that it is grey market. </p>

<p>I noticed the lens body, when connected to the 1Ds camera body, has a little/very slight movement at the reticule. I believe the technical word of the lens part in question is the "rubber ring" contact of the lens body. See attached picture of the area in question.</p>

<p>When I say slight movement, I mean maybe 0.5mm of play (when try to move the lens body by hand) while it is fully connected/locked into the 1Ds body. <br>

<br />Just for comparison, my 24-70mm L lens body also has slight movement when fully connected/locked into the 1Ds body but its movement is maybe 0.25mm of play. </p>

<p>So my question is: do you also experience this type of connectivity movement with your lens-to-camera body? Or is this abnormal. I have a feeling it's very normal, it's just that it is a little more noticeable with my 70-200mm versus my 24-70mm.</p>

<p>Should I send it back to the retailer or send it in to Canon using the warranty? </p>

<p>If you are talking about <em>rotational</em> movement, similar to when you would mount or un-mount the lens, I believe a slight amount of play is fairly normal. Seems to me I've had it on SLRs back from my Minolta Days through my Canon 7D, and it can vary quite a bit between lenses.</p>

<p>I don't think they can design the locking mechanism with that close a tolerance to preclude all motion, at least not without making it more cumbersome or complex.</p>

<p>If you mean rotational play all my EOS bodies and lenses show it. Both my 70-200 lenses (F2.8 non IS and F4 IS show about 0.5mm of rotational play) and my shorter lenses show a bit less. It has no impact on IQ as far as I can tell. I think it is just cost based engineering. You clearly can make a system with no play (my Leica lenses and bodies have no play at all and even my Canon FD system has almost zero play) but it will cost more.<br>

I think it is just trying to keep prices down - with manual focus lenses the engineering was much more robust as the lens was always being manipulated by clumsy humans. AF lenses are clearly designed to be less solid. I have several L series lenses with a significant level of plastic parts which would never happen in the old FD days. High tolerance engineering is expensive (see Leica for more details) and most people don't care that much as lenses become obsolete more quickly as technology advances.</p>

<p>I have the same lens and use it with a 5DII. I've noticed the same type of movement. Its very,very subtle and I don't feel it all the time. I even notice it with some of my other smaller lenses. So I've always assumed this is normal.<br />Its a fantastic lens. Have fun with it. Its probably as sharp as, if not sharper than my 100 2.8L macro.</p>

<p>Two of my L lenses show perhaps less than 0.5mm movement. Another (my 24-105mm) doesn't. I wouldn't worry about it.</p>

<p>I have this movement on my 5Dmk2 with a 24-105, on my 5Dmk1 with a 17-40, and on a 30D with a 17-55. Several other L lenses have some rotational movement as well. I was concerned at first but never found a real issue with it. Go, and enjoy!</p>

<p>Thanks everyone! Also, yes, I meant "rotational movement". </p>

<p>My 70-200 F4L IS and my 400 F5.6L have rotational movement with my T3i, 6D and 70D. My 24-105 F4L has no movement on any of the 3 bodies. My non-L lenses have no movement, even the 50mm 1.8.</p>
