    I think the Thypoch Simera 75mm f/1.4 ASPH will find an audience among photographers who like a more tactile shooting experience again, like Leica M-mount camera owners, and who are looking for images with character rather than pin sharpness.

    The Thypoch Simera 75mm f/1.4 is a lens that rewards those of us who love working with fast telephoto primes. It offers a modern take on the classic portrait lens – sharp but soulful, precise but expressive.

    Of all the 75mm M-mount lenses I’ve shot — the Kipon 75mm f2.4, the Voigtlander 75mm f1.5 — the Thypoch Simera f1.4 is the best built and the most capable wide open. That’s my take after several weeks on the M11.

    If you're a portrait or model photographer or say weddings or anything where you need a bit of arty swirly bokeh, a fast lens for say low light photography, this lens is fantastic.

    I think it's just a really, really, really good lens, a lens that is definitely to go in my bag, especially for weddings and portrait kind of stuff when I'm especially using the M system to be a little bit more discreet.

    [F]or my money this is the best portrait lens that you can buy right now for the Leica M-mount, and it's really giving Voigtländer some heat.
