A new Leica SL firmware update and the official release of the Leica Summilux-SL 50mm f/1.4 ASPH lens are rumored for early 2017 (the shipping date listed online is January 15th, 2017). Some low-res sample photos with the new 50mm SL lens can be found here and here.

The new Leica Summilux-SL 50mm f/1.4 ASPH lens is currently available for pre-order at:

    Good news about new Leica SL firmware update. Maybe even some details?

    • Maybe later, this is all I got for now.

      • David V. Kutaliya

        Thank you very much.

        • Adam

          Should be a AF update.. As the 50SL is pretty crippled as the SL currently is.

          • David V. Kutaliya

            Adam, you mean faster autofocus?

          • Adam

            Yes, that’s what I’ve been told by Leica. BUT they may add other things to the update 😉

            The AF is a bit slow right now, and sometimes completely misses it’s mark. Sort of like what you’d expect from a lens hunting in the dark. But this happens in broad daylight. I guess it’s just that the SL algorithms haven’t been setup for shallow DOF lenses.

            AF is on average for this lens. Nothing like the Q or 24-90SL.

            Though a lot can be done with firmware, so I’m hopeful. Simply look at Fuji and what they’ve done with the 35/1.4 XF.. It’s completely usable in a fast paced wedding scenario now. Whereas on launch, and without firmware updates… terrible.

          • David V. Kutaliya

            So, we must be patient and wait 🙂

          • Adam

            Yes.. Also the lens isn’t out yet anyway. So you’ll have to wait either way 😉

          • David V. Kutaliya

            Thank you:))

  • Hans

    Damn. Giant lens for a big camera.

    • Neopulse

      I agree. Mirrorless perks I suppose.

      • Hans

        What’s the point of mirrorless when the lenses are so enormous? Am I missing something here? All of the SL lenses are 2x or 3x bigger than anyone would want.

        • Karim Ghantous

          The SL is not a general purpose camera, unlike the M. You don’t take the SL with you on vacation. 😉

          Mirrorless does allow you a huge choice of adapted lenses, as well as modern native lenses. SLRs can’t use M lenses. Even the Olympus half-frame cameras can’t.

          You also get more accurate focus with mirrorless, thanks to live magnification. Etc. etc.

        • Neopulse

          But I have to admit, the optical quality they output is pretty much second to none. Although that is to be expected from Leica.

          • sperdynamite

            Well it’s 2nd to Zeiss Otus lenses and will definitely be 2nd to X1D and Fuji GFX output. But it will cost you the same or more to put a kit together.

  • stevo

    I bet this will be stunning!!

  • CHD

    I still can’t wrap my head around what a monstrosity that 50mm lens is…..seriously, an 82mm filter size???? I’m sure the quality will be top notch….but seriously how much better is it going to be then say mounting a 50mm Lux??? Obviously you lose AF but still….this new lens is HUGE.

      • Adam

        You can check out my blog, I’ve shot with it.. But not sure if it’s polite to post links here. So you might want to just do a search on google.

        • Ric Ricard

          I believe it is fine to post relevant links.

    • sperdynamite

      As someone who owns the 50 Art for Nikon, I have to agree with you. I only use that lens on jobs or special projects. It’s enormous, and makes the relatively small D750 or F100 as big as some medium format cameras were I to want to travel with it (I don’t). Sony is doing the same thing with their 1.4 line up. Personally I think it’s a big mistake. No mirrorless camera is ready for prime time vs a Canikon so don’t saddle people with these gigantic optics that eliminate one of the biggest advantages of mirrorless. A line up of F2 and 1.8 primes would be welcome IMO.

    • chrisgull

      I suspect that one reason is to reduce internal vignetting wide-open.

      • CHD

        Yes but why?? Vignetting is literally the easiest thing to correct in post that I can think of….not to mention a tonne of people add vignetting deliberately anyway. I would much rather have a smaller lens and some vignetting.

        • chrisgull

          It’s not about fall-off. Internal vignetting leads to cropping of the defocused CoC – “cat-eyed bokeh”. This seems to be a problem with all f/1.4 lenses, to a varying degree.

      • chrisgull

        Then again, in the photo above the front element doesn’t look that big.

  • John-F

    While the Leica Camera website still does not have a PDF file for this new lens, I noticed that a new version of the Leica SL brochure (catalog) was added (see and that page 27 of that brochure includes MTF charts for the new Summilux-SL 50mm ASPH,

    IMHO, when the Zeiss Otus Apo-Planar 55mm f1.4 was first introduced, it was an extraordinary lens, and showed great courage and leadership from Zeiss. But then, the engineers at Leica had a good hard look at it and said … we can do better … 😉

    Have a look at the MTF charts below. And remember that, unlike the Otus, the Summilux-SL has autofocus and a dedicated camera and sensor (and possibly, a new higher megapixel version coming soon):

  • its soooo big. :-/

    it has to be a no compromise lens

  • Brennan McKissick

    I don’t get it.

    • Les

      If it’s anything like the S lenses, then you need to shoot it in difficult conditions to “get it.”

      I expect that it will hold contrast even in the worse back-lighting (sun in the frame, subject in shadow), and it will have amazing detail everywhere in the frame, even wide-open. It will also display no colour fringing, ever, at any aperture, no matter how harsh the lighting ratio.

      I concede that Leica’s recent lenses are very expensive, but they deliver. The micro contrast is amazing, and this opens-up a lot of photo opportunities that were previously impossible.

      • Adam

        Actually, it’s strongly digitally corrected. If you don’t mind that, you’ll like the lens. But it’s nowhere near Otus quality IMHO. Rendering wise, I’m on the fence.. In some images I see rendering I love, in other images I’m not a huge fan and question if I’d be better off with the 50Lux-ASPH-M
