If you have an M mount camera, this adapter lets you use the hundreds of Canon lens models made since the late 1980's, many very reasonably priced. The Canon adapter maintains the quick focus of the camera, and was selling at a steep discount on Amazon.

Initially I wanted the official canon adapter, however these were out of stock with no date for restocking so I bought this instead. Although I can’t compare this generic item to the branded Canon adapter, I have to say that so far I have been really impressed with what it does. All my EF lenses (Canon 100-400l mk2, Canon 100 macro, Sigma 150-600, Sigma 150 macro) work perfectly with all functions operating as I would expect. At at least half the price of the Canon adapter, I have no hesitation in recommending this item.

This lens is one of (if not THE) best lens Canon makes, period. It is the premier "sports lens" in the industry, and it has that title for several reasons:1.) BUILD QUALITY: It's built like a tank.2.) WEATHER SEALING: couple with a 1 series body, as soon as it starts raining, everyone else will be scrambling to keep their cameras dry.3.) SUPERIOR OPTICS: color and contrast from this lens are excellent.4.) IS: I bought this lens because of the IS.My former 70-200 lens was the Sigma 70-200 f/2.8 HSM. I'm not going to sit here and lie saying the Canon completely blows the Sigma away- it simply doesn't. The Sigma is a fine lens. It is also built like a tank, the HSM is almost (when I say almost, I mean by milliseconds- ie barely noticeable)as fast, and the colors and contrast are superb- almost indistinguishable from an L lens. There are a lot of "almosts" in this paragraph, I know. The Sigma is "almost" perfect, the Canon IS PERFECT. If you are willing to pay the substantial price difference for perfection, more power to you.The main reason I purchased this lens was not because it was white, not because it has a red ring, and not because it's a Canon. I bought it for the IS. I am a sports shooter and I found myself limited in the shutter speed I was able to use with the Sigma. I am a big proponent of the 1/focal length (x 1.6 on my 30D) rule. At 200mm, I would need a shutter speed of at least 1/320 to prevent camera shake. When using flash, I would have to use HSS for the flash to work at that shuttter speed. HSS significantly cuts down on flash output. I would rather use my cameras maximum x-sync speed (1/250) most of the time. This is where IS comes in handy for me. With the Sigma at 200mm/ 1/250 I would get blurry shots, with the Canon using the IS I'm safe. I can even go several stops slower than 1/250 if I desire. The IS is fantastic and is definitely worth the extra $$$.

This lens adapter fits my new canon eos M50 to my Tamron and irix and sigma lenses that I got before this camera. They all fit ef-s mount for the rebel t6 camera

So you finally decided on getting the EOS M (it's flaws considered). I assume you are a canon user, have a couple of good (canon EF/EF-S mount) lens lying around and would like to be able to use those on you EOS M. Just like me, you love your canon dslr but sometimes wish you can travel light but still be able to enjoy the canon ecosystem that you have grown to love. If you are what I assume you are, get this lens adapter.I took a gamble and bought a "like-new" used from a seller at Amazon and was very happy with a purchase. For anything more than $150 I probably would think twice. But I am not taking a start out because of the price. This adapter handles every canon mount lens I threw at it. The build quality is nice. The design (the way it attaches to the eos m; the included, detachable tripod mount) is well thought of... just perfect.

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

Da d Canon Adapter weiterhin nicht lieferbar sind, habe ich mir für diese Adapter entschlossen. Anfangs funktionierte er mit allen meinen Objektiven, aber als ich heute d Sigma 150-600 Contemporary anschließen wollte, kam es zu diesen Problemen:1. Blendeneinstellung steht immer auf F00 egal ob ich im M, TV oder AV-Modus bin.2. Im AF-Menü Punkt 1 - AF-Betrieb d Canon R6, ist nur M eingestellt u das kann ich nicht ändern.Diese Probleme treten z.B. nicht mit dem Canon EF 100-400, den Canon EF 100 Makro bzw. anderen Canon-Objektiven auf u d Sigma funktioniert sowohl an de Canon 80D als auch an d M50 problemlos.Jetzt werd ich noch d Viltrox versuchen und auf d Canon warten u d Commlite, sollte es keine Lösung geben zurückschicken ...Leider muss ich dafür einen Stern abziehen u einen f d fehlende weather-sealing, was ich zwar wusste, aber eigentlich sollte das bei so einem Adapter für eine teure Kamera quasi Standard sein ... u wie gesagt, gäbe es d Canon-Adapter für ca. 30 Euro mehr, hätte ich ja eh diesen gekauft ...Wer aber kein weather-sealing benötigt u auch nicht mit d Sigma 150-600 arbeitet, für den passt d Adapter sicher (sehr) gut ...Nachtrag: es dürfte wirklich am Adapter liegen, dass d Sigma 150-600 nicht erkannt wird ... habe jetzt zwischen Adapter u Eobjektiv noch einen Kenko 1,4-fach Konverter dazwischen geschaltet u damit funktioniert alles ... diese Lösung ist aber leider nicht zielführend ... werde d Commlite daher retournieren u auf d Canon Originaladapter umsteigen.Wichtiger Nachtrag: ich habe nunmehr d Canon-Adapter (mit Steuerungsring) bestellt u dieser funktioniert einwandfrei mit d Sigma 150-600 ... er sitzt auch strammer.Zuerst kontaktierte mich der Hersteller v Commlite u in d Folge d Lieferfirma VC Mall in Shenzhen, China, u zwar Bella ... wir hatten einen regen u auch sehr raschen e-mail Austausch u problemlos refundierte mir d Fa VC Mall den Kaufpreis via amazon ... für diese schnelle Abwicklung und umgehende Problemlösung zumindestens was d Kaufpreis betrifft, gebühren VC Mall nicht nur 5 sondern 6 Sterne!Trotzdem, Vorsicht wenn jemand d Commlite Adapter mit d Sigma 150-600 contemp verwendet will, ich kann nur sagen, dass er bei mir nicht funktionierte (Stand 9.4.2021)

New to 50mm lens game. I have been using a sigma 10-20mm since I started shooting photos around 3 months ago.

Shout out to canon for making afordable quality.
