Sigma Mount Converter MC-11 For Use With Canon SGV Lenses for Sony E

This works really well, I use my Sigma 150-600 contemporary lens with an EF mount on my Sony A7IV. Since it's not a Sony lens, the frame rate is limited. The autofocus seems to work pretty well, not quite as good as my Sony lenses - but I really don't have any complaints. It's been good enough to photograph rodeos and air shows. I am not a professional photographer but a reasonably okay amateur. Perfect for what I needed.

I am happy with this product. Works great for me and I save a lot for new lenses for my A7SIII Sony camera

Works great with the Sigma ART 35mm f1.4. Not blazing fast but it will use the PDAF of the 'II' series Sony A7 cameras like my A7II. The quick firmware updating was relatively painless and supersedes the lens firmware so you don't have to worry about getting the Sigma lens dock(s). As with any adapted autofocus lens, the accuracy and speed is not perfect. I found it struggled in very low light unless I could find contrasting areas and some have said AF-C works a bit more reliably than AF-S, which is contrary to how I usually use my AF lenses. Build and finish are good, above par for your usual lens adapter. The box is your expected black and white Sigma affair like with their lenses. Overall, probably a must-have if you're adapting several Sigma lenses to the Sony bodies but makes less financial sense if you're only using one (like I am).

I originally bought a cheaper version of this adaptor on Amazon and it turned out to be bad, either poor focus or unable to change aperture, I returned it and went for the more expensive, this adaptor from Sigma. It has not issues at all with Canon EF lenses or Tamron lenses for Canon, I have several Tamron lenses, 70-200 G2 2.8, 35 m 1.8, 15-30 2.8, and many Canon lenses, they all perform perfect, autofocus works great for my needs (no fast photography) and I am able to change the aperture.

On the a6300, having used the Metabones and Commlite adapters, this thing is far, far better. While it only officially supports Sigma EF mount lenses, I have found that a number of Canon lenses work as well (however, you will only have AF-S and AF-C modes). For example, the Canon 50mm 1.4 USM, which doesn't work at all on the Metabones or Commlite, works on the MC-11 quite well. You can even get a degree of focus tracking by setting your shot priority to AF and choosing AF-C (Wide seems to work best). No, it's not what you'd get from a Sony native lens, but it's quite usable. My Canon 70-300mm IS USM takes comparable images, and performs almost as well in AF as the Sony G 70-300mm. Certainly there are reasons to buy the Sony, but for most, this would an effective bridge. On supported lenses like the Sigma 150-600mm Contemporary, I have to say it's almost like using a native lens. I say almost because under normal shooting conditions I wouldn't be able to tell the difference; some native lenses perform far worse, some better. I have tested the adapter with these non-Sigma lenses (assuming AF-S or AF-C mode) - Canon 24mm IS USM - Works Canon 40mm STM - Works Canon 50mm 1.4 USM - Works Canon 18-135 IS USM - Does Not Work Properly Canon 70-300mm IS USM - Works Canon 75-300mm IS USM - Does Not Work Properly Sigma 150-600mm Cont - Feels like a native lens. Quick update - I shot a lot of pics at the Indy 500 this weekend using the a6300 and the Sigma 150-600mm Cont. The combination performed quite well, but you really have to know your AF modes to get the best performance. The only negative I can think of is that it doesn't support EF-S lenses, which is a shame and the only reason I have to hang onto my Commlite adapter. PS - If this review helped, or if you're just bored and enjoy clicking things - could I trouble you for a "Yes" vote below?

I made the switch from Canon to Sony. I didn’t want to spend thousands of dollars on new lens so I got this adapter. At first I was super skeptical, but once I started shooting with my old lenses, I was super happy with the quality of my photos and overall how it was able to function with my new camera. It is cheap compared to similar products, but it does the job. Overall worth the expense!

Just as described ! Great purchase .

This works as described. I have a Sony A6500 and I have previously purchased a Fotodiox adapter, and that only worked on one of my lenses. After I returned that one I was deciding between the Sigma MC11 and Metabones. At $150 cheaper I decided to give Sigma a try first. The Sigma MC11 work for all my Canon branded lenses, including: EF85/1.8 EF35/1.4 EF70-200/4 EF24-70/2.8 and they all focuses very fast in both AF-S and AF-C modes. However, it doesn't work with my old Tamron 17-35/2.8-4 and nor does it work well with my old NEX5N, which did focus with Canon lens but very very slowly. Update 2017 Aug 17: Recently I have been using the adapter on my EF85/1.8 for some indoor sports on very dim venue. Probably one of the toughest condition for AF systems. (typical setting is f/2, 1/500, ISO8000) and the focusing speed and accuracy was excellent. I have not had a new Canon body for 10 yrs (had a 1Dmk3 before) and I now appreciate the advancement in AF technology in the past 10 yrs.

Para ser sincero, adquirí este adaptador por la recomendación de alguien más. Si bien no funciona el modo de enfoque automático en video, puedo usar mis objetivos canon como esperaba (principalmente en foto) he usado otros adaptadores completamente manuales por qué no ofrecen ninguna otra prestación, este adaptador permite volver a usar tus objetivos de otras marcas en tu cámara Sony, no con todas las prestaciones como tal, como el steady shot. Para mí ha resultado el mejor adaptador, no tengo problema en usar el enfoque manual para video por qué la cámara tiene la opción de focus peaking y ayuda bastante, para lo que quería y era volver a usar mis objetivos canon para la foto es excelente. Para mí es mejor usar mis viejos objetivos al lente de kit, que no es malo pero es una vieja costumbre, cualquier objetivo que hayas adquirido sin formar parte de un kit es mejor.

Encaja perfectamente en el cuerpo de la camara y con los objetivos, no tiene holguras rara y se queda firme y bien sujeto. La comunicacion del cuerpo camara es excelente pues noe dado ningun fallo de comunicacion hasta ahora. No pierde velocidad en el enfoque, ni da falsos enfoques. Muy buen producto para utilizar los objetivos de la antigua montura canon a los sistemas nuevos sin espejo. No aporta peso extra que se note a la camara, ni la abulta en exceso.

I love it when I can get something that is is both extremely useful and very well made. This is the case with the MC-11 from Sigma. Changing camera systems has always been financially prohibitive for me until now. I've invested heavily in Canon, with a 5D4 and multiple L class lenses. The camera and lenses are fantastic (albeit pricey) but the reality is that I'm not as young as I was and having to lug close 4KG of gear everywhere was becoming a bind. And so I switched to Sony mirrorless, and because of this great little gadget I can use all my EF mount lenses on my new E mount body, I can confirm the EF 16-35 L F/4 IS, the EF 20-75 L F/4 IS, the EF 70-200 L F4 IS and the EF 100-400 L F4 ii IS all work fine. This may sound counter-intuitive. Why put huge, heavy, "old-fashioned" Canon DSLR EF lenses on a new Sony E-mount mirrorless body? Well, 1) because you can, 2) the Canon DSLR L class lenses, despite being older and being phased out for the new Canon mirrorless RF equivalents, are optically truly exceptional and being able to use them occasionally or even just until I can get hold of similar Sony lenses, is fantastic, 3) the sunk cost in the Canon lenses is not small, and the second re-sale value has dropped hugely recently - selling them therefore is less attractive, and the thought of shoving them in a cupboard never to be used again is a shame. I've only had the MC-11 short time and done some basic testing, but so far so good. The only "feature" I've noticed so far is that the a7Cii IBIS seems to be deactivated when using the MC-11 with the above lenses, but as each of them has their own lens image stabilisation this is isn't an issue, but it maybe something to check if your EF lenses don't have IS. The fact that this thing exists and works (despite the disclaimer from Sigma about it being compatible only with Sigma EF mount lenses) is a miracle - allowing me to continue using my older lenses and saving a fortune by immediately avoiding by replacing them with the Sony equivalents. It's pricey (there's no glass in it, just fresh air between two mounts), but it's worth it.

他の方のレビューも確認しながら、半信半疑で購入しましたがタイトル通り使用したレンズでは全く問題なく、AFもCANONのカメラと遜色ないです。 レンズはEF24-105F4 IS L、100F2.8 IS Lです。 かなり昔のEF50F1.4は残念ながら、認識したり、認識しなかったりで(認識しないほうが9割)でちょっと残念です。 費用たい価格は十分です。
