VILTROXEF-EOS M2 Speed Booster 0.71x Canon EF Lens to EF-M Mount Speedbooster for Canon m50 ii m6 ii m200 m50 m6 m5

Adapter seems to be very well made. Feels solid. It is a pretty simple step up size adapter which also allows the cameras electronics to communicate with the non native lens. Seems to do the job well. Wish i’d purchased this a couple of years ago.

Works great, no problems!

I had an old Canon EOS 80D that broke. And still had 3 EF lenses for it just sitting around, 35-75, 70-300, and 18mm. Since I replaced the 80D with the M50, those three lenses were unusable until now. This Valtrox Lens Mount Adapter EF-EOS M2 fit my Canon M50 perfect and gave those old EF lenses new life. It’s amazing that this adapter with those old EF lenses makes the picture and video quality so much better! I was getting a communications error on the camera at first, but a simple cleaning of the gold contacts on the old lenses solved that issue. I can’t speak for the other Canon cameras this adapter will fit, but if you have a Canon M50 and some EF lenses, it’s definitely worth the investment!

I got a new camera and didn't want to chage my lenses. This mount works perfectly. Its easy to install and deinstall from tripod. All autofocus properties work well, and it was a great value.

The combination of this speed booster and my Canon 50mm f1.8 lens is pretty solid! Love the quality of my photos and I can’t wait to use it more.The only con I found about this product is that it drains my battery even if my camera is off. I also read that in multiple other sources but I can confirm that it does happen. As a temporary fix, I remove the battery when my camera is idle.

The media could not be loaded. 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.

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

i found my dream lens the canon ef mount 24-70 2.8 l lens and immediately bought this adapter fyi the tripod mount will not work with the mark 1 small rig m50 camera cage

I like this mount adapter its very good working with mirrorless camera 📷 and its not expensive

Cuestiones técnicas no me atrevo a opinar, no soy fotógrafa, sin embargo, embonó a la perfección con la cámara Canon EOS Mark II, y el lente 50mm, el material es bueno y al sacar unas fotos se ven muy muy bonitas, llegó antes, todo perfecto.

Well made.. works fine...no problems or issues...cheaper than the camera brand...highly recommended

ürün gayet iyi. ihtiyacımı şimdilik karşılıyor. ben genelde full frame yakın bir görüntü elde etmek için kullanıyorum. tatmin edici düzeyde. tavsiye ederim.

Good adaptor - works fine.
