    <strong>Supports USB-free Firmware Upgrade </strong></p>
    <p>Firmware of the lens can be upgraded through camera instead of using USB port, which not only meets the requirements of firmware upgrade and appearance design, but also avoids the incompatibility problems caused by different computer operating systems.(Note: this function needs to be supported by camera)</p>
    <p><strong>F1.8 Bright Aperture</strong></p>
    <p>Maximum aperture F1.8,bokeh effect is easily achieved ,which brings you more fun during photographing.</p>
    <p><strong>New Mechanical Structure, New Coating Technology</strong></p>
    <p>YN50mm F1.8 II has all the product advantages of the last generation. By improving the mechanical structure and coating technology, its focus accuracy, auto-focus speed and light transmittance are increased. Furthermore, it can control backlight ghost and glare.</p>
    <p><!--more--></p>
    <p><strong>Durable Metal Mount</strong></p>
    <p>YN50mm F1.8 II adopts chrome-plated and high-accuracy metal mount. It’s wearable, corrosion-resistant, and highly consistent with the body of the camera.</p>
    <p><strong>0.35m Closest Focusing Distance</strong></p>
    <p>Compared with the first generation, the closet focusing distance of YN50mm F1.8 II is shortened to 0.35m.You can get closer to the object for photography and enlarge the object.</p>
    <p><strong>Focus Modes: Auto Focus (AF) and Manual Focus (MF)</strong></p>
    <p>YN50mm F1.8 II supports auto focus and manual focus. The focus mode can be selected according to practical requirement.</p>
    <p><strong>Focus Distance Indicator is convenient for you to estimate the distance and the depth of field.</strong></p>
    <p>YN50mm F1.8 II has 7pcs of aperture blades, which helps to take picture of circular defocused spots or helps to stop down and take picture of 14-star effect.</p>

    EF 50 1.8 STM clone?

    There is no info about the AF motor used, but I don't think it will be STM-like, since they would use the silend focussing to market the lens.
    From what I can tell it is a Mark II with more aperture-blades and a shorter min. focussing distance, as well as different markings on the outside.

    I wonder how super the bokeh is.

    Seeing as it's identical to the older Yongnuo 50mm lens except for new coatings and new electronics and a very important red ring I imagine the "bokeh effect" to be pretty much identical to the previous one.

    The older Yongnuo lens is clearly better than the Canon 50mm 1.8 II (I own both). The seven bladed aperture makes a huge difference.

    See: https://petapixel.com/2014/12/27/comparing-optics-40-yongnuo-50mm-f1-8-125-canon-50mm-f1-8-ii/

    I haven't compared it to the Canon STM because I haven't tried that one, but I'd imagine the Canon STM is the better lens all round.

    I thought i heard somwhere that Yn was just remaking canon lenses whose patent had expired?

    Doesn't make any sense because the optical layout of the Yongnuo lenses is unrelated to the Canon ones.

    Their 60mm macro is full-frame, unlike the EF-S 60mm macro!

    You are talking about the only exception.
    All their lenses are canon clones.

    No, they are not.

    They are imitations, for sure, but not clones, because the optical formula inside each lens is very different to the Canon original (and, at least in the case of the 50mm, superior!)

    Please, dont make me google all formulas for you.

    Thanks for the links: The 2nd iteration of Yongnuos lens is very promising in terms of IQ (corner sharpness/resolution), noise of AF motor and (at least for me) a distance scale.
    Maybe a good "bridge solution" to the EF 1.4 50mm IS ... if it will ever materialize or a solution of another lens manufacturer.
