The product works good with my Canon mirrorless camera with Sigma Ef 18-250mm lens with all functions. But the cost of the product is only Rs.7500 in canon showroom. This product is in great demand and not in stock so they are selling at an extreme price. If you can wait just place an order with canon and get it at a lower price

It's nice to be able to use my other canon lenses on my Canon m200

This adapter did the job! I can now use all my Canon, Tamron and Sigma lenses on my new Canon m50.

Canon EOS M Mount adapter is a must have for all Canon EOS M users if they have other Canon EF and EF-S lenses. The construction is solid and heavy. I used several Canon EF-S and EF lenses and they work fine with the adapter. Highly recommended.

It may fit some of the Sigma lenses, however without the automatic focus.It focused easily and perfectly with Canon lenses

I have to hand it to canon. The M3 is fantastic. I used to be impressed with the T3i and the SL1, but the image quality of the m3 is the best canon camera I have owned. The body is compact, and has an excellent and intuitive layout. The Fold out screen is great for high or low shots including (shudders) Selfies. The best part of the camera, is that with a few inexpensive adapters, I can use nearly any lens ever made. It has revived my relationship with my old manual focus lenses. I have even started perusing thrift shops and have struck gold, finding 2.8 and faster lenses for less than the price of a good burger. Heres what I like and don't like about the camera.Pros:- small size,- good button layout for quick access to most used items - exposure compensation, manual focus zooming,- solid build construction- Wireless image transfer to Iphone ( no wifi network required, but wifi on phone needs to be on)- rapid shutter response times 3 times faster than SL1.- ability to adapt manual focus lenses without extra glass ( FD mount, Nikon mount, pentax mount, screw mount)- Amazing image quality- Focus Peaking when manual focusing is spot on.- Half the size of the SL1- Large screen is easy to see and does reasonably in the sun.Cons- slow focusing with USM and Standard Focus motor lenses (all older technology) I was really disappointed, but not surprised. The hybrid focus system used with the M3 is better geared toward STM system lenses. You will notice a difference compared to just about any of canon's other SLRs and it may be due to the adaptor.- slow start times - 2x as long as the SL1- adapters needed for everything - you need them for every kind of lens you mount to them. the canon eos to M adapter is 200$, the Photodiox one is excellent for 40$- sometimes it's too small. the menu button gets pressed a lot if I am using a large lens.- Heavy. - is half the size of the SL1 and weighs just as much even though it has less going on inside. but is made out of better material.- Screen does well in the sun but can be difficult to see if there is glare.Overall this camera is 4 out of 5 stars. It is everything I wanted from canon except speed.Image included to show the incredible detail and color. It was shot with a 55-250 IS lens with no post processing.

I make collage art and build models and dioramas. These three things taught me along the way that I needed to learn to take better photographs, and so I started early with a Canon Powershot and then moved on a few APSC sensor Canon cameras I love and have in my collection along with a plethora of Canon prime lenses. This is all fine, but I've wanted to have a more portable camera and so, given the fact that I already have all the glass I would ever need (well, you can never have too much glass!), I decided to research the CANON EOS M over on YOUTUBE (big mistake). All the YOUTUBE reviews on this camera make it seem like it was DOA. And that is NOT TRUE. I've owned this camera now for a couple of weeks and I love it. Simply love it. With the lens adaptors I can try out and experiment with all my lenses, and it is so much fun. For the price, this camera is not only a great bargain but it is simply the right choice if you are already a Canon user. I loved the quality of the pictures (I haven't had any problems with the infamous focus--remember I use mine 99% of the time on a tripod shooting art on a table top) and the quality of the videos. I love it so much in fact I bought a second one. I don't particularly care how late Canon got to the mirrorless camera party (to use a common expression being thrown around the different communities), the bottom line is that the camera performs well for my needs and sometimes that is the right approach to take. WHAT DO YOU WANT THE CAMERA TO DO FOR YOU? How are you going to use it. It's a basic question, and with me once I did my research and found found the answer, the Canon EOS M rose to the occasion. My advice to prospective buyers is to do the research on the ground. Go and check out the camera at a store and get a feel for it. (Mine, BTW, came with the firmware up grade of 2.0.2.)

I bought this product because my 580EX2 started to act up.Not having the funds to afford another 580EX2 or the 600EX-RT at this time, I did my research and decided to buy the Sigma EF-610 DG SUPER.I read the reviews about how cheap the flash feels.I beg to differ, it looks and feel fine to me. We have so grown to accept Canon products as a standard (with good reason), so if it does not look or feel like Canon it is no good. The plastic battery cover was another problem to other reviewers, for me I am no less confident of the durability of this cover than I am of the battery cover on my EOS Canon 7D.I do not buy a speedlight to drop it on the ground from 8 feet up so whether or not it can stand up to the shock of being dropped on concrete from 8 feet up was not a concern I had before purchasing it. My major concern was if this product would trigger my other canon speedlights if I used it as a master. Well it does trigger all of them, the 420ex, the 550ex and the 580ex2.The menu on the back is a no brainer, one does not even have to consult the manual.It has all the power I need. It compares favourably with the 580EX2 and is far more powerful than the 430EX2.The exposures are spot on, equal to my 580EX2. If I am to fault the Sigma, the flash gun head cannot be tilted up and down in increments like the Canon. It has an angle where it clicks in place when adjusted upwards and will fall back down if it is not set at that particular angle. One has to consider cost when buying a product. For the price it is an excellent product. I would still buy it even if it cost a bit more (by the way I am a Canon Purist). but there are times when an immediate need has to be fulfilled. I am happy with my purchase. I cannot yet comment on its durability yet. More anon.
