    The best Sony APS-C Lens First of all, do not listen to people or reviews who say this lens isn’t sharp. They’re wrong. All you have to do is look at sample images on Flickr. If your concern with this lens is sharpness don’t worry about it. Not only is this lens sharp the micro contrast is surprisingly good for a cheap Sony lens. The 28mm full frame equivalent is my favorite focal length. This lens is 20mm which on an APS-C camera is 30mm. That extra 2 mm of telephoto is absolutely wonderful. The difference is minor but it’s still so so versatile. The perfect in between lens. For everyday use this lens doesn’t leave my A6000. I only take it off when I want to do portraits. My primary application of this lens is street photography. IMO it is the best 28mm’ish lens for the Sony APS-C system for street photography.

    You get what you payed for It is exactly as advertised: small, light, efficient with AF… Not the sharpest lens on the market but for its value it holds up as expected. I’m very satisfied with it as it is a very versatile focal length and I do use the Clear Image Zoom on my a6500. I have been using the 20mm for travel and dance photography/videography. I upgraded to this lens from the Sony 16mm f2.8 and am much more confident now with the image quality (less distortion, chromatic aberration, blurry edges…), would recommend the 20mm for those of you deciding between the two!

    Form factor is AWESOME I bought this lens for travel photography…because it is so small and light. The sharpness is very good and the speed (f/2.8) is an improvement over the kit zoom lens. The focal length (30mm equivalent) is perfect for a travel lens.

    The best lens for 6xxx series of Sony cameras. I had the Minolta’s FF 20/2.8 and Sony 16/2.8 and this little pancake runs circles around both – in every respect. It produces very sharp and contrasty images

    The auto-focus is quite and instant. The effective 30mm focal length is perfect for general plinking.

    It can even be used on the full frame cameras, and with APS formatting turned off it produces compelling panoramic images.

    Mounted on a6xxx camera makes the system almost pocketable.

    extremely portable – perfect fit for all sony – e-mount cameras, FULL FRame and aps. i use it on A7RII with aps-c mode turned off. This way i get approximately 22-24mm equivalent field of view , after cropping the dark corners or using “Clear image zoom” set to 1.2. i can get an equivalent of 1:2 landscape panorama using full frame 20mm view.(cropping top and bottom). Versatility of clear image zoom on a7rII is incredible if i set it to max = 2.0 ration i get a standard / wide 40mm view with this lens with NO noticeable loss of sharpness, excellent for 16×20 print!!
    super light weight for backpacking and travel. Hood NOT needed, virtually no flare or ghosts without hood. OEM hood makes no difference,, thus can be avoided to maximize portability.
