Rumours about Canon mirrorless...

                  "Depending on your count: If you ask for mirrorless Nikon adapters: not more than you. The TC17 has some play and most lenses as well, be it Nikon or Sigma. Everything else would surprise me. They have to turn in the bayonet. This is not possible without some play. For Fuji, there's also the converter for the 100-400 and the metabones to Nikon adapter."

 

   I find this strange, I have been checking fpr play and  slack here in my lenses and tele-converters and extension tubes, apart from a little " Rotational play" which is normal for any lens and is due to the lens locking pin elongating the lens locating hole, I found nothing, and being heavy lenses this would be a worse case scenario,  I hope this is not the play you are talking about?

   Just to be clear, as you say, there has to be some "clearance" between each bayonet, however well manufactured this can be  very minimal (a few microns), to the point that there is "no perceptible movement" experienced.

  A ball race has a clearance for example, but it shouldn't have any play. (within it's designed usage)

    I've just checked the Tammy 150-600 mm and the Nikon 500mm with or without the tele-converter+ the Sigma macro, nothing other than a tiny rotation.

 

 

 We have to limit the description of play as a general looseness/ slack; angular/lateral/verticle/horizontal slack, normally there should be none. 

 

 So just to be clear;

<p style="color:rgb(40,40,40);font-family:helvetica, arial, sans-serif;">                                           I hope we are not talking about rotational play here!
