Play and Rattle in 70-200 Mount


Recommended Posts

Unfortunately I dropped by A7RII with 70-200 F4 attached (on the first day I had the lens).  Good news is that everything has worked perfectly.  However the lens mounts to the body with a little bit of play, which is sort of annoying.  I am wondering if I replaced the metal mount ring on the lens (attached by four tiny phillips screws) by switching the plate from a lesser lens, if this would solve the issue?  Since the lens was new to me, I don't know if play was present before the drop.  In addition when I gently shake the lens there is a subtle rattle present, I believe part of the autofocus or stabilization mechanism?  Again I don't know if that was present before drop or not, I literally had the lens for an hour before it fell out of my golf cart!  It produces beautiful images, focus is fast and accurate, and stabilization appears to work fine too...

A7Sii with same lens. Mine has a wee bit of rotational play when mounted. I dropped my lens alone onto its lens hood about 30" to concrete sidewalk. Chipped a bit of plastic off beneath the black rubber ring but that's about it. Mounting ring / flange not distorted since it wasn't mounted to body at the time.

Thanks...yes I just have a bit of rotational play.  Any thoughts on the rattle?

Probably some small piece broke inside the lens.

 

I had my lens snap in half (and been fixed since) and noticed that there are lots of plastic parts that can break inside.  

 

There is a plastic clip that holds the front and rear parts of the lens together by the focus ring.  Since there are bit of open space inside where the two connects, what you're hearing is most likely s chipped part moving within from the drop.

 

If it doesn't affect the performance of the lens use, ignore the sound......
