Product Description

EF-EOS M2

This 0.71x Lens Mount Adapter from Viltrox allows a full-frame Canon EF-mount lens to be mounted onto a Canon EF-M-mount camera. While doing so, the adapter's optics help to maximize the connected lens's apparent angle of view while providing a one-stop increase for the camera over the lens's aperture range.

If a lens intended for 35mm film or similarly-sized full-frame camera sensors is connected to a Canon EF-M-mount camera, this adapter condenses the light from a lens designed for 35mm film or "full frame" camera sensors and projects it onto a Canon EF-M-mount camera's APS-C sensor. This allows the APS-C sensor to utilize more of the light gathered by a connected lens, which effectively reduces the crop factor while making available to the sensor an additional one stop of light for each of the lens's f/stop settings.

  • VILTROX EF-EOS M2 mount adapter is designed to allow Canon EF-mount series lenses to be used on interchangeable-lens digital cameras that compatible with EF-M lens.
  • Can increase the lens 1 f-stop, increasing the amount of light into the virtual background, can better highlight the theme;
  • Focal length is multiplied by 0.71 based on the original (equivalent focal length =focal length x 0.71), which helps enlarge 1 level aperture.
  • By adapter mounting it can achieve functions of EXIF signal transmission, AF(autofocus) and adjustable aperture, etc.
  • Firmware upgrade is via the USB port.
  • With auto focusing function;
  • Signal transmission using PIN gold needle, greatly enhance its transmission performance;
  • Ring at the bottom with 1/4 screws, which can easy installed on the tripod or other fixed bracket;

5.0 out of 5 stars Great if you have a lot of EF Glass
By DaVo on April 25, 2019
One thing that hasn't been clear to me and I don't blame this on the manufacture Viltrox but on the many reviews out there. I didn't notice until I began to use the speed booster that it will only work with EF Lenses, not EF-S lenses. Yes, this should have been a given with the idea being that this will take a mirrorless crop sensor camera and turn it into a full frame camera.

Now on the subject of Full frame. I'm using this with a Canon M50. Which has a crop factor of 1.6. This booster gives a plus 0.71. Meaning that this crops 1.136. For example EF 50mm 1.8 with the adapter is an 80mm with the booster it is a 56.8mm and also drops the F down to 1.2.

The images and video were all shot using the Canon 50m 1.8 STM. the first image is with the speed booster with aperture at1.2. The second is with the booster at 1.8. The third is with the Canon EF-m to EF adapter with the aperture set at 1.8. The video is with the speed booster.

I have used this both for images and video. With video, I haven't really noticed any issues other than the motor makes does make more noise than usual and the autofocus seems slightly slower when changing the autofocus from one subject to the other. The 50mm is dead silent when used without the booster, so I'm guessing that this is the motor in the booster. When tracking I've noticed no issue beyond the focus motor sound.

Who should buy this and who shouldn't? If you already have a collection of EF Full Frame lenses, slap this thing on and Bob's your uncle. If you are just starting out and on a budget, the EF-M to EF adapter may be a better option because you can use both EF and EF-S lenses. EF-S lenses tend to be cheaper and THEY WILL NOT WORK WITH THIS SPEED BOOSTER.

5.0 out of 5 stars Absolutely awesome + 1 f-stop!!!
By David Palafox on August 14, 2019
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!
