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.
But who am I to tell a mount blacksmith about play? :lol:
thxbb12, I know what you mean with the ND filter. In the Canon G10-11-12 it's inbuilt which I found very clever and useful. I'm not complaining about the Fuji method to readout with lower amplification or higher scanning speed (don't know what's technically going on), but in reality it doesn't freeze as much as a mechanical 1/8000 does.
The 56/1.2 APD did come with a ND filter for that reason. The electronically shutter was not so fast when they put the package together.

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;

No, we're not talking about any rotational movement. How did you check the clearance or play? Camera mounted on solid tripod head or lens and body in hands? Holding both in hands I don't feel any play. Putting the body (or the long lens) on a solid tripod head I can move the lens up and down a little bit.
Sure. At Rolex prices or Chinese "genuine Rolex" copies?
