Fotodiox Lens Mount Adapter with Aperture Control, for Nikon G-type, DX-type to Canon EOS M Mirrorless Cameras

I bought this as I have a Nikon DSLR and wanted to use my Sigma 24-70 f2.8 on my Canon M5. I knew it would only work in manual focussing and my sigma allows me to change the aperture on the lens so all ok. Connected it to my camera, attached the lens and fired the shutter and nothing happened. A quick google search and in the cameras custom menu you have to set the camera to allow shutter to be fired without a lens attached. Did that and all works perfectly as it should.

The silvery ring is used to manually adjust the aperture, and it doses the job. However, due to the design of Nikon lenses only 10 degrees rotation of the ring will change the aperture all the way from minimum to maximum or visa versa, making it fairly difficult to guess what f number has been selected WHEN THERE IS NO MARKINGS ON THE RING. I appreciate that the ring cannot be graduated for every lens that may be used on the adapter, but even a crude Min/Max points or, even better, 5 or 6 clicks would have made the adapter much easier to use.Having said that, I still think it is a good product and with a minor modification will be perfectly usable.

I use this for my Canon M50 and being a Nikon guy for many years, was happy to know that I could use my Nikon lenses. Be advised, there are no electronic contacts so you do not get autofocus or aperture control from the camera. You need the aperture ring to turn (which the 1.8D has). Works perfectly especially with focus peaking.

If you have a Canon EOS M and also a Canon EOS DSLR. then this is almost an essential piece of kit. It is very well made, right up to the standard of Canon's own version, which costs over twice as much. I've used it to mount each of my Canon EFS lenses. In particular I used it to mount a 55-250 zoom and used it to video the Swans at Martin Mere, I mounted the combination on a hide clamp, using the tripod bush that's included and found it very easy to use. Indeed it was easier than using the EOS 550D,

I have tried a couple of M42 adapters but this was the best others had problems with infinity lock and way too much play between camera body and adapterThis has none of that but lens is slightly off center (not as much as others) but if a hex key was supplied with it for adjusting it would be perfect
