Sigma MC-21 Sigma EF Lenses to L-Mount Reviews

Great, with one mistery

By Young
Rated 4 out of 5
Date: 2022-08-26

Everything is fine, works well with canon ef lens(not sigma), though af speed is much slower. The mistery is that if I use f1.2 lens(50 f1.2, 85 f1.2), indicator shows f1.3 instead of f1.2 ...

Works with Canon glass too, no AF at all though

Adapter fits L glass nicely, very secure to the S5 as well. However, the auto focus does not work AT ALL. If you shoot manual focus you're good to go.

Fits perfectly

I used many converters in the past. But this one is best one I have ever used. Very well build quality. No rotating gaps.

Works with all my EF glass

The converter works great. I've used Canon L series glass (16-35 f2.8 version 1, 24-105 f4.0 version 1), Tamron glass (24-70 f2.8 version 1, 70-200 f2.8 version 1) and the Sigma 18-35 f1.8. The only hiccup is that the Sigma lens will automatically crop to apsc mode.

DIDN'T WORK AT ALL

My digital Leica CL is too early , 2017, to work with it. Did all upgrades to lens, and Leica to NO AVAIL! ANY SUGGESTIONS WILL BE APPRECIATED!. I KNOW I CAN RETURN IT, BUT I WANT IT TO WOR! LENS sIGMA 150-600, CANON MT, LEICA 5348337...

Best adapter so far...

I have tried many other brands and this works quite well with the EOS EF lenses that I have on the Leica SL2. There is some hunting with a few lenses and there was one lens that didn't register properly but overall pretty good. Works great with Sigma EF lenses as advertised and Sigma does not guarantee that it works with Canon EF but I have had good luck so far. Manual Zeiss ZE lenses work perfectly.

IT WORKS REALLY WELL!!!!

The adapter allowed me to use my collection of Canon EF lenses L on my LEICA SL2-s. I am truly happy as although I will de using mainly my LEICA M and L lenses, I will be able to fill the gaps with the EFs. THANK YOU SIGMA !!!!!

Using this adapter with a Panasonic S1R I just brought. I'm coming from a Canon camera and using Tamron lenses. It works great with the tamron 24-70 lens. The auto focus is fast and works great. The other tamron lenses don't work as well and I must use it in manual mode which is not a problem. I have a Tokina 100mm macro and it won't work at all with that lens. Also have a canon nifty fifty which works just fine. I will use this adapter until I upgrade to panasonic lens but for now it's great for what I need for now.

Can the lenses of the Canon L line be adapted? Like the 24-105mm II and the 85mm 1.4?
Asked by: Isaac
I contacted Sigma directly because I own a number of Canon "L" lenses and a Leica CL. Below is the response from Sigma: Thank you for contacting Sigma USA. Our MC-21 is designed for Sigma Art, Sport, and Contemporary lenses only. Unfortunately the MC-21 will not work with any of the current Leica cameras, but will with future models.
