Thanks, JT!
Andy,
@acnomad, is right. I bought a sony a7ii when the price was going down and a cash back on top. Just before the a7iii was about to appear.
Had there been a Nikon mirrorless at that time - at a comparable price, I would have most likely have gone for Nikon.
With a dumb m42 adaptor, this is great way to revive the lenses from that area. Plentiful available.
The build of the Tair is really good. Really enjoyable to use and with pleasing results.
Rather big and heavy though for a 135mm lens.
We have a dedicated thread for this lens on the forum:

Seems there is a way to use it on Nikon F-mount cameras as well: Klaus does.
