Fotodiox Lens Mount Adapter - Compatible with Canon FD & FL 35mm SLR Lenses to Canon EOS M (EF-M) Mount Mirrorless Cameras

This is the second EF/EF-S to EOS M adapter that I've purchased.The first was a similar product but different brand. It was a complete failure.Both adapters cost the same amount, $39 at time of purchase.The Fotodiox arrived the next day. The other brand took nearly 3 weeks to arrive (I think that was a sign).The Fotodiox packaging is nice, it could be given as a gift.The adapter comes with lens and body caps, some competitor adapters do not have caps.No instructions were included, but the assembly of lens to adapter and adapter to body is pretty straight forward.If a person can't figure that out, they likely won't be able to operate the camera.This Fotodiox adapter is 100x better than the other brand I have, NO comparison at all.I shot 50-60 images the first day, not one error using the Fotodiox product.The other brand I could get 8 to 10 photos, then would get an "Err 60" error message - not good.I've tried 3 different lenses with the Fotodiox adapter and all work as they should.The electronic functions work flawlessly with the Fotodiox adapter. Honestly, AF seems faster with the EF lenses than with the native M mount lenses, this may not be reality, but all lenses tested did work very well.The only issue I have encountered is not with the adapter, but with a lens and Canon M50 combination. While using a Sigma 105mm 1:2.8 Macro HSM lens, the lens itself somewhat gets in the way of M50 red lamp AF assist beam. Not a deal breaker as the Sigma lens and Canon still work very well together. This combination really can produce great images.The Fotodiox EF and M mounting flanges are matte finish metal, the casting and machining look good and result in a solid connection of lens to adapter, adapter to body. There is very minimal rotational movement at the lens to adapter, and adapter to body, not enough to cause camera errors, as with the other brand adapter I have.The Fotodiox has approximately 0.5mm of rotational movement = very good. My other adapter has ±2.5mm of rotational movement, resulting in continual camera error messages.The body housing looks like metal, but is some sort of plastic, or polymer.It is well made and I don't foresee any issues as the important mating surfaces are metal.Possibly the only negative is the tripod adapter. I have not had an issue, but understand how others claim it is a bit loose, or sloppy when fully tightened. I believe this minor issue can be corrected with the addition of a simple thick paper shim, or very thin metal shim.When the tripod-mount knurled nut is FULLY tightened, there is a little "wiggle".If using large lenses, this minor issue may increase. So, be prepared to either permanently bond the tripod mount to the adapter body, or experiment with a shim to tighten things up.I give it a 5 star overall, even though I only offer 4 stars for Material and Durability.The body housing could have been a metal shell, and the tripod mount issue could be resolved. Neither are deal-breakers. This is a very good adapter.I wish I would have purchased this adapter to begin with.

When I purchased this item, it had just appeared on Amazon, and there were no customer reviews. But I have been buying Fotodiox products for years, and their quality is consistently excellent. I had been looking at the  Canon EOS M Mount Adapter  and a couple of other brands, but when I saw the  Fotodiox Pro Lens Mount Adapter  at less than half the cost of the Canon, it was a no-brainer--go with Fotodiox. With this affordable adapter, my new EOS M camera should become the most versatile tool in my kit!Then before the shipment arrived, two customer reviews were posted here, reporting that the device does not communicate complete information between lens and camera and is unusable with IS and manual focus lenses.My bad. I should have checked the specs. I immediately ordered the Canon adapter, planning to return the Fotodiox. But when the Fotodiox arrived, I thought, wait a minute--I haven't even given it a try. What's it gonna hurt?Well, gosh, the Fotodiox DOES work with my IS lenses-- Canon EF 28-135mm f/3.5-5.6 IS USM  and  Sigma 17-50mm f/2.8 EX DC OS HSM . I tested both lenses with IS switched on and off (don't have any non-autofocus lenses, but I've tested manual focus on these lenses, and it works). It also works with my  Canon EF-S 60mm f/2.8 Macro USM .So, autofocus is spot-on, and image stabilization definitely works with this adapter. (Not only is this noticeable in clearer pictures, but I also can hear the stabilizers working.) Aperture and shutter speed info are displayed on the camera's LCD, and if I get an exposure wrong, there are the usual flashing red warnings--which CAN be overridden if I choose. Exactly as if the lens were directly attached to the camera. I don't see how the Canon brand adapter could work any better.There is a lot of chatter in photography forums about how slow EOS M autofocus is, esepcially with EF lenses attached. I was concerned about that because I LOVE my EF 28-135. And it's true; the autofocus is slower than the 22mm pancake--but not as clunky as I was expecting. AF with the Sigma, on the other hand, seems to be about the same as the 22mm pancake.The Fotodiox adapter is made of very well-machined metal, and the finish is excellent. No wobbling, rattling or play anywhere. Lenses seat smoothly in the adapter and click solidly into place. With the adapter + lens assembly attached to my camera, it feels like one seamless piece of equipment.My adapter did not include front/rear caps, but an EF-M cap and a EF or EF-S lens cap should work with it just fine. They're just lying there in the bag, anyway.I give it a five-star endorsement, no questions!

For its price, it's amazing how good this product is.I use it all the time to mount my Nifty-fifty lens on my Canon M50 mark 2, and it works like a charm for both video and photos.

The unit feels good in the hand, all of the contacts were well aligned and appear to be of good quality materials. The ground finish on the mating surface was uniform and clean. The feel when I was mounting it to the body was clean and tight in all the right ways. I placed a brand new lens and a much older EFs lens that has seen plenty of use and they both locked into place and there was no sign of off axis movement. Overall I'd recommend this adapter. In addition to the function the markers were well applied and seem like they'll wear very well.

There are two things strange about this adapter. First the 1/4 inch screw tripod screw fitting in the base is off center. Looks in the photo like it's in the center. Second the bayonet ring fixing (tiny) screws were loose. Other users have had the same problem with Lens shake as a result. You need a jewelers screwdriver to tighten three tiny screws, then its OK.The detent (click) that indexes the blue clamping ring is very weak and makes it extremely easy to shift the blue ring from the "install" mode to the "aperture" position, or back, and you don't notice. Considering this claims to be PRO product the design/QC should be better.

The silvery ring is used to manually adjust the aperture, and it doses the job. However, due to the design of Nikon lenses only 10 degrees rotation of the ring will change the aperture all the way from minimum to maximum or visa versa, making it fairly difficult to guess what f number has been selected WHEN THERE IS NO MARKINGS ON THE RING. I appreciate that the ring cannot be graduated for every lens that may be used on the adapter, but even a crude Min/Max points or, even better, 5 or 6 clicks would have made the adapter much easier to use.Having said that, I still think it is a good product and with a minor modification will be perfectly usable.

I use this for my Canon M50 and being a Nikon guy for many years, was happy to know that I could use my Nikon lenses. Be advised, there are no electronic contacts so you do not get autofocus or aperture control from the camera. You need the aperture ring to turn (which the 1.8D has). Works perfectly especially with focus peaking.

If you have a Canon EOS M and also a Canon EOS DSLR. then this is almost an essential piece of kit. It is very well made, right up to the standard of Canon's own version, which costs over twice as much. I've used it to mount each of my Canon EFS lenses. In particular I used it to mount a 55-250 zoom and used it to video the Swans at Martin Mere, I mounted the combination on a hide clamp, using the tripod bush that's included and found it very easy to use. Indeed it was easier than using the EOS 550D,

Doesn’t work..not auto focussing nor will it let me manually focus with any lens, put the kit lens back on and all works fine so it’s not my camera
