Frequently asked questions

A speed booster, like the VILTROX EF-EOS M2, is an adapter that allows you to use Canon EF lenses on EF-M mount cameras, such as the Canon M50 II or M6 II, among others. Besides enabling the lens mount compatibility, it also effectively reduces the focal length multiplier by 0.71x, which means you get a wider field of view and more light, enhancing low-light performance and potentially improving image quality.

While the VILTROX EF-EOS M2 is designed to adapt Canon EF lenses to EF-M mount cameras, there might be compatibility issues with certain lenses, especially third-party ones. However, most Canon EF lenses, including primes, zooms, and professional L-series lenses, should work well with this adapter, providing full electronic communication for autofocus and aperture control.

The VILTROX EF-EOS M2 adapter is designed to maintain electronic communication between the Canon EF lens and the EF-M mount camera, supporting autofocus functionality. While in most cases, autofocus speed and performance are preserved, there might be slight variations depending on the lens and camera model used. Some users may experience a minimal lag in autofocus speed, but it generally remains functional for most photography and videography purposes.

The VILTROX EF-EOS M2 includes optics that can affect the image projected onto your camera's sensor. Due to the 0.71x magnification reduction, the adapter can actually increase the amount of light entering the lens by about one stop, potentially enhancing image quality in low-light conditions. However, the impact on sharpness and distortion will vary by lens. Most users find the image quality excellent, with minimal to no noticeable degradation.

So I got myself a Canon M50. Very similar to the Canon 77D I already owned features-wise, but significantly smaller and lighter. I was a little bummed that I needed to get all new glass because of the EF-M mount, but then it turns out that there’s adapters that let you use your EF and EF-S lenses on the EF-M mount, albeit with the same 1.6x crop factor as my 77D, both being crop-sensor cameras. I'd been watching M50 review videos on YouTube and in one of them someone mentioned the Viltrox EF-EOS M2 Lens Adapter. Honestly, it sounded too good to be true at first. So you’re telling me I get an adapter that will make my EF lenses look almost their actual focal length (about 1.1x instead of 1.6x) AND also gain a full f-stop for about 150 USD? Yeah, right… I kept watching reviews on the Viltrox adapter until curiosity finally got the best of me. I ended up buying one from Amazon, hoping for the best. First thing I did, I had to try my beloved nifty-fifty (EF 50mm f/1.8 STM lens). Using the Viltrox adapter it now looks like a 56-57 mm lens (50 * 1.6 * .071) which is not bad at all. But wait, when using the lens and adjusting the aperture on the camera, it didn’t stop at f/1.8 but rather all the way down to f/1.2! My lens, brand new, goes for 125 USD on Canon’s website. The 50mm f/1.2 also on Canon’s website goes for 1,349 USD. I’m getting the aperture of a 1,300 dollar lens for less than 300 dollars (lens + Viltrox adapter). Sure, it’s not quite the same but I’m very much a beginner/enthusiast, so it's more than enough for me right now. That’s an excellent price point for such an awesome aperture on a prime lens. That’s only talking about the one lens, though. Got any EF lenses sitting around? Pop them into this glorious thing right here and get almost full-frame images out of them with extra aperture. Couldn’t be happier with my purchase. Get this adapter NOW! ... show more

    • If you own an M50 this product will open up you lens choices drastically.
This product, and all their products have changed the way I use my cameras. I can now use all my EF mount lenses with my Canon M50. The build quality is as good as Canon, or any other high end lens I've used. Fit was perfect and all electronics worked flawlessly (auto focus and stabilization). This now expands the lenses made for the M50 from 6 to all the EF lenses (which is many). The one thing to take note, before purchasing, is that only EF lenses work on this adapter and not EF-S mount lenses. I don't understand why they can't make a speed booster to allow the use of myEF and EF-S lenses though. The non speed booster version of this product (the one with no optics in it) that they make, allow me to use both types, why can't they make a speed booster that accepts all my EF and EF-S lenses like their cheaper adapter? Besides that one issue, I still recommend this product. It will open up your lens choices for your Canon M50 and is made of nothing but the best quality material. ... show more

    • First one would not work with my M50 but seller worked with me and sent replacement that works great
Update: Got my replacement from the seller and it works great! He was very easy to work with. I will buy from him again! Bought it to use with my Canon M50 and Canon 100mm F2.8L and Canon 24-105 F4 lenses. The adaptor worked one time. I didn't need to use it again until now and it will not work. It will not recognize an aperture and stays in manual focus (even though my camera and lens are in auto focus.) When I fully push down the shutter release button it says error: camera and lens connection is not working. I have cleaned the lens and camera connections, attached it as stated in the directions to no avail. Since it's been over 3 months, I cannot return it to Amazon but the seller is going to allow me to send it back for an exchange so I’ll repost an update once I receive it back and test it out. Service and communication from the seller as been great. ... show more

    • Simply amazing!
What an amazing little gadget. Before I bought it, I watch a bunch of YouTube videos and read a bunch or articles on it. Needless to say, I was eager for its arrival. I attached it to my Canon mirrorless and then attached my Canon f/4 24-105mm lens to it.. The reading on my screen: F/2.8. Awesome. Next, I tried it on my 70-300mm 4-5.6 zoom and tried it at the long end. My screen displayed F/4. Again, awesome! So.. I was able to take a photo a stop lower ISO. It may not sound like a lot but... My main reason for this purchase was for use indoors in the auditorium at my kids' school. They never have it very bright up on stage and the amount of light keeps your camera at either a high ISO or a shutter slow shutter speed. When taking photos of your kids, so much more detail can be kept at 3200 vs 6400 ISO. Just awesome. I wanted a full frame camera but not the size or cost... For $156 (At time of purchase) it was WELL worth it. Quality.. Build quality is great. I also use a regular Comlite adapter and I'd say they're about the same build. Photo quality.. Seems fine. I'm happy... I'm also just a Dad who takes pictures of his kids. If you want a professional opinion, I'm not the right guy to provide it. Am I happy with the purchase: YES ... show more
