    First sentence proofread as well as a Chianese instruction manual. No hate tho, love the articles.

    • I am covering a Chinese product, I am trying to be authentic 🙂

    These are actually re-branded Fuzhou Focusafe (7.5mm) and Shenzhen Golden Vision (25mm) lenses; don’t know who makes the other 2 lenses but the 35mm looks like a cheap CCTV C-mount lens and the 50mm is probably the same as SLR Magic’s, only with a Leica mount. I’ve tried Focusafe’s 25mm and 50mm f1.8 lenses and they were Ok for the price, and presumably Golden Vision’s 25mm (it’s usually branded “DISCOVERY”) is somewhat better, so at least the 7.5mm and the 25mm should be good value for the money, but they are a pain to use for stills shooting because of their de-clicked aperture rings with not well calibrated f stop numbers.

  • Tbh, there are a bunch of brands like this, using the same design even. You can find ’em on AliExpress, eBay and Taobao/Tmall.

    Of course the more known China brands are SLR Magic and Zhongyi (ZY Optics/Mitakon). Maybe even Laowa, Yongnuo, Meike and Neewer. But there’s more unknown ones like Kerlee, Zonlai, Kaxinda, Wesley, Hengyija and Kamlan. The latter seems related to the CEN (/LEKO) company. They also have the exact same HD.MC lenses seen in the line-up from this article. They’re actually APS-C covering C-mount lenses. These are the cheapest on AliExpress, where they sell at the Rocks Photographic Equipment store, name-/brandless, with a green ring (you can search on AE for ‘green circle lens’).

    Tripod manufacturer Sirui has shown off a 35 and 85mm f/1.2 at a P&E 2016 tradeshow… yet, there has been no mention since.

    Concerning f/1.1 lenses. Actually Sakar was going to launch Kodak labelled lenses… a 8mm f/3.0 fisheye, 25mm f/0.95 and 50mm f/1.1, but these as well don’t seem to have found the light of day. One guy (Joshua Son, Street Smart Photos, dulynoted (DPReview)) seems to have found them in China, though.

    In any event… these are not new lenses. Everything on the Chinese market seems intertwined to one another somehow. Usually companies don’t bother to pay exclusive rights for the manufacturer design. So… the factories making these are free to make ’em for anyone who wants them. I guess that happens a lot and here as well. That’s why there’s no cohesion in this line-up.

    Think of these more in the direction of Fujian C-mount lenses. Sorta toy lenses/vintage vibey. Not the greatest, not the sharpest edge to edge, horrible chromatic abberation, weird flares, etc… but for the little too pay it might have a quirky character that can be useful to you at some times.

    I think Kerlee looks a little bit more promising, already, they look like they’re going for that Zeiss styling. Personally, I think the most promising might be the Kamlan 55mm f/1.2. Wouldn’t mind giving one of those a go.

    • The 50mm f/1.1 for M mount (rangefinder coupled) is new – maybe not the design, but the coupling. I have not seen any other Chinese lenses that are rangefinder coupled before (except Iberit).

        …nor have I seen any other 24×36 50mm f/1.1 Chinese lens with 7 elements in 6 groups:

        – SLR Magic: 6 elements in 5 groups
        – SainSonic Kamlan: APS-C only, 5 elements in 5 groups
        – Kodak-branded Sakar: m4/3, 2013 prototype, much smaller.
