Thanks for pointing that out. I didn't think about those MF cameras.
That said, the latest Sinar branded lens I've seen is a Symmar S from the 80's
I'm in NYC and have never seen an M or Hy-6, not here or anywhere else in the US. I've seen plenty of AFi's. I've been in stores and seen people buy AFi's. Many times. The only Sinar branded lenses I've ever seen in person are LF type board mounted ones. Going back to the 90's (80's? I'm getting old) almost without exception they have been Rodenstock.
I'm not complaining about the ArTec or it's available lenses or accessories. When it was announced I enquired about buying one. I would have liked one with the lenses available. I have 2 of those lenses for my Alpa now, they're great. But it's not wise to want something you can't get, and that seems to be the case with a lot of Sinar stuff in the US and Canada now and for the last couple years. Sinar was the dominant player here for a long time but I have not personally met a photographer who uses their backs or cameras newer than the p series.
