New to Nikon. Just received "new" D850 body as well a "new" Nikon 70-200mm 2,8E. There is a "small" noticeable rotation play after the lens is locked to the body. Purchaed from a well known retail seller who says "no worries" as long as the camera/lens works They "Nikons are like that" . A call to a authorized Nikon repair location "could be a problem but would have to measure the "amount of play". A call to Nikon resulted in there there should be "no" play.
I've owner several other brand an never felt "slippage". The system seems to work fine but I worry the "play" will get worse.
Any one experience the same movement in the body and lens as I'm describing? I have no other Nikon lens but I have tried the Nikon 105mm 1.4e. withe same outcome.
There is a pin on the lens and a slot on the body ..if slot too wide or pin too small it will move
I don't have the 70-200mm F2.8E, but the G VRII I have does have a very, very, small bit of play (not enough to mess with CPU contacts) and its 9 years old or so. I can slightly, ever so much, move all my lenses when mounted. Lenses like the 24-70mm F2.8G have almost none, for example. That has been the case with all the lenses and Nikon camera bodies I've had over the past 11 years (D80, D300, D700, D800, D750). Perhaps the "E" lenses have more play, since they no longer have the aperture lever to hold them in place as well as the "G" and earlier models.
In theory, rotation would affect aperture stop down on a mechanically controlled aperture (non "E" lens) though I think we are talking about a totally immaterial degree.
Also consider that no rotational play whatsoever, might be so tight as to not actually allow the locking mechanism to fully engage. This would be like a simple door latch where the door doesn't close far enough to allow the latch striker to extend securely into the striker plate. Push on that door and it would pop open whereas a bit of play would allow the striker to fully and securely seat.
It hasn't ever affected focus, or anything else, it's just something I notice when I put the lenses on the cameras.
