Sigma MC-11 Autofocus Tested On The Sony a7S III

[@HarvVideoAudioStuff]

Enjoy guys! :)

[@CraigSinclair]

Some useful insight Harv. Did you happen to notice any noise from the MC-11 as it was focusing in video mode?

[@bardofhighrenown]

I'm looking at picking up one of these adapters for my Sigma SA lenses. I absolutely love my lenses, but as you pointed out the mount is probably at the end of it's life with the discontinuation of the Sigma SD Quattro (H). My SD1 is still my main camera, and probably will be for years to come, but it has limitations and the idea that I can pick up a used A7iii or an a6600 and get a massive improvement in autofocus, tracking, image stabilization and high iso performance without needing to buy a whole second set of lenses saves me thousands of dollars and means I can bring both systems out with me without needing to pack two sets of lenses. Even if the stills performance isn't stellar, it would be very difficult for it to be worse the SD1's autofocus which can't hit the broad side of a barn.

[@nicedward7544]

Lmao the AF performance will be miles ahead of the sd1. I still use the EF version on a7Riii and it works like native Sony glass. Only sigma lenses work in both video and stills though. I shoot sports in stills mode with a 200 EF prime from 1990. It focuses faster than it did on a Canon 5div.

Hi Harv! I love your content, brother. Much Appreciated. :)

[@AbdurahmanMabrook]

This video is the reason why I subscribed.

[@richard-sim]

Very informative video - thanks! I've recently upgraded to a Sony full-frame from APS-C, and had been trying to find out without much luck if the MC-11 would let me use Canon lenses as they seem to be available much cheaper used than Sony's. The lack of video AF for non-Sigma lenses is disappointing, but exactly what I wanted know - their documentation is infuriatingly vague on compatability, which must be deliberate.

[@frankfeng2701]

Another benefit of buying EF mount glass for Sony camera is to mount all kinds of adapters, such as ND, focal reducer, CPL.

[@idahofallsmagazine3691]

Nice piece. It's almost jarring to see a youtube video like this without all the nauseating jump cuts.

[@GeraldBertramPhotography]

Great video! Almost like it was tailored made for folks like me that have Sony and Panasonic gear. I use EF glass on a Metabones with my GH5S. Great to know if I buy Sigma EF glass that it will also work well on my Sony gear with my MC-11.

[@darylkotze548]

Great video! Thanks for the heads up!

[@seanwhitevideo]

Thank you so much for testing this, Harv! Really helpful info; I'd hazard a guess that the MC-11/Sigma glass combo would also enable good autofocus on the FX6? That might be a good way of getting optical stabilisation using the Sigma 24-70 2.8!

[@HarvVideoAudioStuff]

Hmm yes I’d say so although I can’t say for sure

[@oasean]

In one of my phone calls to Sigma's office in New York during perhaps 2019, a Sigma agent told me openly that Sony had shared its autofocus algorithms with Sigma. But yeah, Sigma apparently is a "thorn in the side" of Canon [04:53].

[@PensacolaEnergy]

Older Sigma 105mm 2.8 DG Macro hsm lens and a7siii ... will mc-11 work? My older metabones ver 2 won't?

[@thomasl4533]

Hello, very nice video and very interesting. I had the chance to test some of my sigma lenses and only the art 18-35 has af working. The 17-50 and the 70-200 (older lenses) af is not enable. Aps c crop mode only works in hd. For apsc lenses if you want to use the full range in uhd you have to go to clear image zoom 1x3 And you loose af. The continuous af produce a little noise with the 18-35, be aware of that if you record audio close to the lens. Thanks again for the tip, i love your channel 👍

[@giacomom2370]

4:30 simple. Focus by wire when trying manual focus is terrible. Particularly in Sigma's DG DN when it's MF is not linear.

[@Whaever_1981]

Thx for the great vid! The only reason why you should consider E mount Sigma Art Lenses is that they are weather sealed. The MC11 adapter is not. Question, how noisy are the AF motors on these lenses? I have the E mount 28 1.4 and 40 1.4 and the 28 is quite noisy :(

[@HarvVideoAudioStuff]

Many thanks, hmm they are noisy to be honest so won’t be great for when you have on camera audio. As far as I can see the only reason to get the newer Sony lenses is that they’re quiet 😂

[@Whaever_1981]

@@HarvVideoAudioStuffCool, thx! :D

[@gkochanowsky]

Harv, thanks for covering the very neglected MC-11. I've been using mine for many years on my a6300, a6500 and a6400 with very good auto-focus results. And recently with my a7S3, also with very good auto-focus results. I also have a very similar opinion of Sigma glass, especially the Art series. I've been very happy with those lenses. However, I noticed in your video what has come to annoy me with this setup. Many of those EF Art lenses are very noisy in autofocus mode when obtaining audio from a camera mounted microphone. Something that I have not experienced with the native Sony glass that I own. As a result I'll be buying the newer Sigma E mount Art series glass in the future for use under those circumstances. That said I'm in no hurry to get rid of my EF glass, because in this new age of mirrorless mounts, the EF lenses can be mounted onto any of these bodies and can always be used in manual mode or with an external focus motor. Thanks again Harv for the video.

[@CARLOMERAZAUDIOVISUALES]

Hi do you get good outofocus on video on the a6400?

[@gkochanowsky]

@@CARLOMERAZAUDIOVISUALES IT works best with the newer Sigma lenses.

[@CARLOMERAZAUDIOVISUALES]

@@gkochanowsky thanks

[@Th3yForgotM3]

Question I had. A problem until I attached the lens after cutting the camera on is that normal when using the adapter that’s the only time it happens

[@_dobleene]

Hola, podrías hacer esta prueba, pero en la A7IV, para ver que tal funciona

[@MikeMena]

I hope you didn't already answer this below! But have you tried any Tamron EF glass with video? It's clear most lens work with photography, that's cool, but I have Sigma and Tamron EF and crossing my fingers :(

[@HarvVideoAudioStuff]

Unfortunately I haven’t yet tried it with Tamron lenses but hope to at some point, my gut says it work work for eye af in video ☹️

[@RafickBottse]

hey Harv, so if i get it right i won't be able to use my canon 70-200 2.8 iii and canon 100mm 2.8 glass with the sigma mc-11 on a7siii in autofocus mode? :(

[@HarvVideoAudioStuff]

Hi, sadly not for continuous AF in video 😒 but should work for stills (albeit not as well as sigma lenses or of course native e mount glass)

[@taurus7228]

Thank you. I wish to buy it. I am actually from the Nikon ecosystem and just bought a sony camera. Do sigma lenses comparatively cost less compared to native sonys? Thank you very much

[@jibmediaconcepts8827]

Thanks for this video

[@kwameryan]

Hi Harv! I know this is an older video, but I am just coming to the point where I'm about to give up on Canon for a reasonably priced hybrid with great dynamic range for video, so I'm gonna get an FX3, but keep my EOS R's for photos and multicam streaming. As you say investing in Sigma EF glass makes total sense for cost and flexibility. Super happy to have a bridge that makes me feel less crazy about the multisystem path I'm about to take! How's it been for you then?

[@HarvVideoAudioStuff]

It’s been pretty flawless to be honest, I now have 4 sigma EF primes and they work as well as my E mount glass. I think I’m going to switch all my lenses to sigma! The only thing to consider is that they’re not focus by wire so you may hear the focus motor from time to time if you have a mic attached to your rig 👍🏻

[@kwameryan]

@@HarvVideoAudioStuff Thanks!

[@wcsdiaries]

@@HarvVideoAudioStuff would the signa ef 24-70 f2.8 work well too on a7siii with this mount? Or only primes?

[@GaelSoucheleau]

Thanks for the test! I'll go for the MC-11 then... Cheaper than buying again all my primes art lenses in E-Mount. The only lens that I'm not sure about is my Sigma Sport Zoom 70-200mm. Have you ever tried this one ? Thanks again. Greetings from France.

[@tederrey]

It works great

[@nightdonutstudio]

They works great even with my a7III. The question is when will it works with canon lens or never.

[@HarvVideoAudioStuff]

Likely never as sigma want people to use their lenses, sadly there’s no incentive for them to have other lenses working with the mc11 😕

[@ThePeopleWeMeet]

Hey there - Do you know if continuous autofocus works with a sigma 18-35 + MC-11 on the A7siii?

[@HarvVideoAudioStuff]

I’ve not tried this combo but it should work 👍🏻

[@ericv4701]

I have sigma 18-35 + MC-11 on A7sIII, it works well on both photo and video, not perfect but it works well for my standard. AF-C , eye AF is decent on both photo and video , again - for my standard.

[@oakiedokee]

So just to be clear the Sigma lenses you were testing were EF mount?

[@HarvVideoAudioStuff]

Yes indeed

I miss your old videos when you were in that closet-looking place. Looks like you went for ambiance with the new look but it seemed a little more cheery before you came out of the closet.

Hi Harv, Do you know or heard if this applies to the FX6 and sigma MC-11

If anyone ask why don't you buy Sony glass then they have not ever looked at the price of Sony glass. I believe Sony is looses out on a lot sales to Sigma and Tamron because of there pricing.

[@HarvVideoAudioStuff]

Couldn’t agreed more, the GM lenses in particular...crazy 🤑

[@AVdigitalPRODUCTIONZ]

Cool...

[@cristiantoma1500]

It clearly says on the adapter that it was made only for Sigma glass. Because in that configuration is no longer an EF protocol lens, becomes Sony native. With Canon glass, it has to stick to EF communication, which is indeed less than ideal.

[@HarvVideoAudioStuff]

I know this, I said it clearly in this video…and yet I still get people asking the question
