Opteka (T2) T-Mount Adapter Compatible with Nikon Z Mount Mirrorless Cameras: Z 9, Z 7II, Z 7, Z 6II, Z 6, Z 5, Z fc, Z 50, Z 30…

This adaptor is designed to adapt "t-mount" threaded lenses to Canon FD/FL film camera bodies. For many years the Canon Bayonnet mount 35 mm film cameras which took the FL/FD style lenses, were the industry standard. These original series camera bodies were designed to fit the entire line of Canon SLR lenses, providing the same excellent performance on the cheapest (TX) models as the most expensive 35 mm film Models (F1, F1n, AE-1, A-1, FTb, etc). This adaptpter allows Telephotos and telescopes to be used with these older style Film camera bodies. In the 1970s the interchangeable standard was developed which led to the t-mount lenses, most noteably for astronomical use, and for telephoto use in large focal length lenses, and the T-mount system would allow these lenses to be used on many different camera brands. Currently the most popular lenses using t-mount are mirror (Catadioptric) lenses. This system continues to this day, and the adapter under review is specifically for using these lenses/telescopes with the Canon camera bodies of that 'vintage' time frame. This well made adapter (t-mount) is cleanly machined, polished, and well constructed, fits the camera body well, (unlike some others I have had in the past), and is strong enough to support the weight stress of a long or heavy lens. The adapter is so well made, it glides on and off the lenses quickly and smoothly, seats firmly at both interfaces, and is a strong stable mount. I have several T-mounts which allow the use of my lenses on different eras of Canon Cameras, both Film and Digital SLR bodies. Highly recommended. Perfect for the use specified.

Item absolutely does NOT fit any L mount cameras, APS-C or Full Frame. I ordered the L mount variant of this adapter and it is much too small to fit into the L mount on either my Leica TL2 or Lumix S5. Lack in product quality assurance and accuracy would lead me to advise against this product and company in general. The product just straight up just isn't what it says it is...

This does not fit the Panasonic L mount. Panasonic S1, S1H, S1R and so on should NOT be in this product's description.

This seems nicely constructed, no cheap plastic parts. The tightening ring has a good solid snug feel to it as well. However...when I attach it to my old 1974 Canon F1 body it just won't snug up completely so there's a bit of play in the connection. I wish the tightening ring would turn more OR there was some sort of set screw. (No instructions that might explain how to adjust the tightening ring travel.) As it is now it's not going to work for my camera. UPDATE! There's a small screw on the outer largest ring. I loosened that up and now the outer ring has more rotation and seats rock solid on the camera body. I'm quite happy now.

The adapter threads nicely onto t mount of telescope and allows attachment on other end of adapter to RF mount of Canon R series cameras.
