Rumours about Canon mirrorless...
#51
Quote:A 500 mm Tele doesn't react on a difference of 0.06 mm (that's what ± 0.03 means  Wink ) With a (heavy) wide-angle, it's another thing. Mind you, you did not measure the play between mount and lens. This adds as well as the play between adapter and lens. So very soon you come to Â± 0.3 mm if it comes worst to worst.

 

Sure you can buy, measure and send back to some extent. If you have enough nerves to spend on this selection...
 There is absolutely no movement with the 500 and the tele/ camera body. I hate any sort of lens play!

 

  I have a Pentax K to M42 adapter, (chrome brass non Pentax) it had quite a bit of movement between the camera bayonet and the adapter, (pentacon bokeh monster)  I isolated the cause and rectified it by hammering the adapter by flattening the mount so the "lugs" were closer to the flange, the play disappeared!

 

   As for buying testing and return/keep..........is there any other method?

 

  As a matter of interest , how many adapters do you own JoJu?
