I purchased this to use a set of older Nikon AF Nikkor lenses with my Sony A7R II. The physical connection fits well, and for all-manual focus the adapter is fine. However, I cannot get autofocus to work. The Sony does not recognize that anything is attached, after multiple tries and with multiple different lenses.Attempting to upgrade the firmware was no help. According to the pictures on Viltrox's guide, there should be multiple files showing up in the adapter. These include the firmware itself, as well as a text file to track version numbers. None of these show up in my adapters' files. When I open the adapter drive, it is completely blank. Trying to add the firmware file shows that the firmware is copied, but then it forcibly reloads the folder and it is blank again. At this point the adapter is a $176 "dumb adapter" that I will likely be returning.

With low expectations, I bought it to see if it would work using my full frame Sigma 150-600mm on a Micro Four Thirds camera to photograph migratory birds in my back yard. I'm no wildlife photographer by any stretch, but for me, the results were impressive. My words when trying it for the first time were "wow, cool!"After some experimenting, tripod shooting obviously worked best, but handheld, I found turning off the camera's sensor shift image stabilization and using only the lens IS produced the sharpest results.The auto-focus speed was "adequate," but certainly light years better than manual focusing. However, if AF performance is a requirement, perhaps you might be disappointed.Right now, the adapter gets daily use on a tripod with a super sharp Sigma 50mm f/1.4 and an EM-1 for broadcast-quality Zoom calls. At f/2, my backgrounds are perfectly out-of-focus, and sharper than any Micro Four Thirds lens I have - surprisingly, minus the annoying "hunting" I get with them, which forced me to only use MF.Highly recommended, as long as you're aware of its speed limitations.

This adapter allows my old Canon EF-mount lenses to be used on M50. It’s built with optics to increase light input by one F stop and reduce the focal length by x0.71. Not sure how that works but when I was changing my f-stop, I was shocked that my 1.4 is now 1.2, just magic. I can still use autofocus and auto iris but won't work on any of my Samyang lenses.It's well constructed and with a little bit of searching the firmware updates can be found, they are easy to update. The reason why it was hard to find is that it the text was in Chinese and I had a problem figuring out which driver was the correct one for my update. It's quite quick and simple to do and only needs to be done once.After setting the adapter up it works really well and I'm very pleased with it.If you are thinking of a speed booster adapter then I would recommend you consider this, great value for money. Don’t get upset when you first use it, check to see if you have the latest firmware. This will fix all the focus and shutoff issues.
