Top lens info: Sigma 50mm ART lens matches the best Zeiss Otus.

Sigma is one of the third-party lens companies making lenses for the Micro Four Thirds system. And I guess you already know about their most recent “ART” lens series. Well, let’s hope they will make some new ART lens for MFT lens too because their recently released 50mm f/1.4 ART lens for DSLR mounts shows a quite impressing quality! SLRgear tested the lens (read here) and the Sigma manages to almost match the $4,000 Zeiss Otus performance:

While the Zeiss does show better performance in the corners at ƒ/1.4 on a full-frame camera, the other optical performance characteristics are pretty evenly matched.

The Sigma sells for DSLR system only ($949 at BH). But I hope Sigma will make a more compact designed version for the MFT system!

  1. Can you stop this kind of buzzfeed eroneous title policy? Does this website really need this kind of dumb trick to generate click?

        1. I’m guessing you’re complaining about this being a DSLR lens but in this case these news are still relevant. why ? because there’s a high probability this particular lens might be released natively for m4/3, being part of the ART line of lenses, of which m4/3 already features 3. And even if they don’t ever release it for this system, it’s still the best adaptable 50mm lens available (in terms of value), Just imagine this lens with a speedbooster O_O!

          1. Who says Sigma won’t ever just change the mount and release any of their DSLR lenses for mirrorless ? Similar companies like Rokinon already do this, besides the fact that Sigma already has release 3 ART lenses for micro 4/3, who’s stopping them from milking their own designs ? why limit themselves to just one market ? there’s no technical reason not to. And as I said, even if they don’t, you can still adapt this lens, better yet, you can use a speedbooster and improve it even further.

  2. Even when they considered to compare micro contrast, this is mostly again a test about sharpness again. Good for the ones who need really need it. But i wished they included pictures real life shots like portraits/people photography so we can see how it renders. Nevertheless, sounds like an interesting lens.

    1. Well, it’s yet to be tested. That’s a reviewer’s job. A Manufacturer can pick a background to show better bokeh – that’s THEIR job 🙂

      Still, I think it’s an incredible lens. MFT has been fortunate. We have fast lenses sharp across the frame from wide open. Full Frame has in that sense been somewhat neglected. I am pleased with results I get when I shoot at F1.2-1.4 on my FD 55mm F1.2 on the 5D, but even my wife notices that the 25mm F1.4 is far sharper.

      The Zeiss Otus is out of reach for most. SLRGear’s review is pretty good, even looking at micro contrast. The sigma’s measured sharpness in the corner is lower, but perceived sharpness is higher (they have a sample pic to explain). It’s really something. Nikon updated their 50’s in the last few years, but Canon is lagging behind, so this is welcome.

    2. Sharpness is a big deal for FF cameras at this focal-length because pretty much all of the fast 50mm lenses by Canon/Nikon/Sony/Zeiss are horribly soft with loads of CA at full aperture.

      These are two rare lenses that are both fast and sharp at full aperture.

  3. Sigma has already made 3 Art lenses for MFT. The Sigma 60mm f/2.8 is at this time the sharpest MFT lens, as sharp or sharper than 75mm.

  4. Yes Sigma did created some lenses with m4/3 but unfortunately it’s not fast enough . F2.8 might sufficient in APSC / FF formats but not in m4/3 .
    A F2.0 lenses are desperately needed if Sigma really want to excel in m4/3 arena .

  5. m43 have 2 good lenses with 50mm 135eqv. … pana is bit faster….but zuiko is smaller and very good performer

    1. Unless you missed something, there are THREE M4/3 lenses that are 50mm equivalents… the Pana/Leica 25mm f1.4, the Olympus 25mm f1.8 and last, but certainly NOT least, since it was released FIRST, is the Voigtländer Nokton 25mm f0.95.

  6. The high end lens vendors kind of disappoint recently. Either Sigma matches their quality at far lower price points or the high end vendors really do not deliver, as Zeiss shows with some of its products made for Sony. Schneider-Kreuznach completely fails to release their long awaited m4/3 line up.

    Leica and Voigtlaender seem to be an exception as their m4/3 lenses are of high quality and not too expensive in comparison to Otus.
