a7r Loose in the lens mount
« on: January 25, 2014, 01:33:01 AM »
Am i the only one to notice this? There is a micro-wiggle in the lens at the mount area (bayonet). I noticed this even on my NEX-6 with stock lenses.

Any thoughts?  Thank you.

I have heard of this in a number of cameras, not all Sony's. If it is, as you say a micro-wiggle then I think it is probably just the built in manufacturing tolerance and is considered normal by Sony. If it occurs with one lens only then it may be wear in the lens, or possibly due to the lens being at one end of the tolerance scale and the camera mount at the other. In any case I don't think micro wiggle is anything to worry about, but that is your call.

Take it to your retailer and have them look at it and your lenses and give their opinion.

Thanks AScot,

All my lenses and gear are brand spanking new. This happens with all my lenses - even the NEX lenses have the same result, not only on the a7r but on my NEX-6 as well. 

Remarkably, the LAEA4 adapter has no wiggle at its lens mount, only the a7r and my NEX-6.
