    This is nut! I thought the FE 28mm would be the smallest AF lens on any a7xxx series. Well, I was wrong.
    I bought this Canon EF 40mm f2.8 STM in July 2012 when it was just released and have not used since I sold my 50D almost 3yrs ago. It wouldn't worth much to resale, a good lens, compact and small so that is the only Canon lens that I've been keeping...until now.


    Sample @ f2.8 and it works great.

    No! I didn't buy the MC-11 for the sole purpose of using it for the Canon 40mm STM.
    It's for this...and maybe more to come in the future.
    Sony OEM lenses have been going big, heavy and why the heck not?

    Maybe because Sony is 28mm, Canon is 40mm?

    I'm pretty sure that the 35F28Z makes for a smaller combo than either of those.

    Maybe it is the Canon flange distance killing the size advantage; it adds 44-18=26mm to the length of a native lens.

    Sadly I could not get it to put the 40mm lens on a Sony body for comparison.

    I have not used mine since last autumn, so here are some mushrooms wide open on the A7

    My bad. I never had the FE 35mm f2.8 ZA so I didn't realized how small and it's the smallest AF lens mounted on the a7xxx.
    @ ArendV, those pictures are nice. I'm still amazed in all these years how Canon could produce such a small quality pancake lens and inexpensive.

    Contrary, the latest FE 50mm f1.8 is not bad overall in price/quality wise except for being slow/noisy.
    I'm sure most users wouldn't mind paying $50 more if Sony used a high speed focus motor on that lens.

    I would be nice to have a native FF pancake lens from Sony but I doubted that.

    SamSS, I'm curious about your impressions on the MC-11. It would seem that it might open up a lot of good AF lenses for Sony E-mount for both FF and APS-C. How does the focusing work on your Canon 40mm with it? I saw a used Canon 24/2.8 EF-S at a very good price recently and my curiosity got piqued.

    (P.S. - And yes, I know about the Metabones and others, but the operation of the MC-11 with specified Sigma lenses with most all focusing modes is very intriguing, especially for the long telephotos and IS.)

    I think the Canon 24/2.8 EF-S STM (aps-c) should work great with MC-11 on APS-C cameras that you have.

    I only have FF cameras. The EF 40mm STM (APS-C) works great with MC-11 on a7m2 & a7R2.
    I don't have any other Canon lens to test with if that is what you're requesting.

    MC-11 with EF 40mm STM on a7m2 & a7Rm2. Focus pretty quick and I have no complain.
    AF-S, AF-C are the only focus modes that are functional. The rest are greyed out.
    Wide, Center and Flexible Spot worked and the rest are greyed out.

    Here is a suggestion, if you already have a certain Canon lens or one that would like buy. GG research and you may find someone else may have the exact combination which could tells its performance.
    I'm sorry couldn't be much help. ATM, my interest is purely with Sigma lenses for the MC-11

    Another example @ 2.8 with flash & a7m2

    I still have not used mine for a long time (should change now with mushrooms showing up) so again two old shots, the second one is reversed using a Meike MK-C-UP adapter resulting in 1,5x magnification and in this case with another 40mm extension 2,5x (for those interested, here is more information, suggest your stay there to have a look at the incredible macro and micro work produced by John Hallmén who also uses a NEX-7).

    Not AF but could be interesting for a size vice comparison.

    Ah the reputable Nikkor 45mm f/2.8 AI-P. I am sometimes still tempted to buy one, although I do not really need it and it is usually overpriced.
    It probably performs similar to the Canon being sharp wide open and having smooth transitions in out-of-focus area's (Bokeh).
    In terms of dimensions they are quite comparable, the Nikon a bit more compact (but the Nikon adapter a bit longer vs the Canon one - 2.5mm to be precise):
    Canon 40mm: 68 x 22 mm & 130g
    Nikon 45mm: 62 x 17mm & 120g

    Would be interesting to know how the Nikon performs reversed.
