I bought this with the sole purpose of adapting my sigma art 18-35 lens to my canon c70. It is built very well, it doesn't wiggle on the camera or lens and so far, operates as intended.

Better than the competition

Better than the competition and it just keeps getting better. Are used it with the canon R6 and it works flawlessly. The control dial on the adapter works without a hitch and I love that I was able to add this feature onto my old EF lenses to be able to change the aperture or whatever you want to send it to. Great little device would highly recommend

Decent Adapter

I got this due to the shortage of the Canon version. It works well and has the extra ring the more expensive Canon version has too. Now that I have the Canon version I can see that the quality of the Canon one is higher, but so is the price. This is a good option for the price.

Awesome

This adapter is probably not the best choice. It fits loosely and doesn't seem to communicate consistently with the auto focus.

It works!

I have always been skeptical with these converters but this one let me put my EF lens' on my RF R6 and they looked amazing. So don't be afraid to buy an RF camera because the new RF glass seems expensive. This works great. All lens functions like autofocus,etc work with this flawlessly.

loose attachment to my Canon R6

I purchased this adapter because the Canon one was out of stock and it does not fit tightly on my new R6. I shoot with a 70-200 mostly so wondered if it was because it was such a heavy lens. I was able to find the Canon Adapter and purchased it to see if that was the case and it fits perfectly! No wiggling at all. While I didn't have any issues with my photos while using this adapter, the wiggling bothered me and it never felt super secure. Canon for the win once again!

Any advantage of this vs. Canon's $100 Mount Adapter EF-EOS R?
Asked by: Chris
I have owned the Canon since the R came out. I have had the Viltrox about a week (Got impatient waiting for my second back-ordered Canon with control ring.). I'm giving it a thorough test and will submit a full review shortly. Here are some preliminary impressions. The Viltrox is nicely packaged but does not come with a pouch. The Viltrox seems to be as well-made as the Canon, although the control ring is a bit stiffer. It is all metal including both mounting rings. It worked just fine on my 16-35 f2.8 L II and 24-70 f4 L, including the control ring. However, the Viltrox does not work on my Tampon 150-600 (original); produces an error message and requires the battery to be removed and reinstalled (Tamron has had some issues adapting to the RF mount.). I have not yet mounted it on my Tampon 28-300. I don't have any Sigma full frame lenses, although their 18-300 and 10-20 APS-C lenses work fine on my M5 using the Canon adapter. However two, when coupled to my Canon 100-400 II L plus 1.4x tele-extender II there is an issue: the control ring does not seem to function, although I can change shutter speed and aperture and it seems to autofocus fine. My Canon's control ring does function properly in this configuration. Adapters can be tricky; I have had compatibility issues with other after market adapters. So, I think it's worth a try, but be sure to try it with ALL the lenses you plan to use. Who knows when the Canon adapter will be available. Hope this helps anyone considering this adapter. Greg.
