Features

  • Compatible with most Sony E-mount cameras

    For use with your existing device.

  • Wide-angle lens for broad composition

    Delivers stunning perspectives and allows you to include more of the scene in the frame.

  • 20mm focal length

    Because the focal length measures just 20mm, this lens is considered ultra wide angle.

  • f/1.8 maximum aperture

    For optimal light gathering capacity, resulting in clear, highly-detailed images.

  • 0.22x magnification ratio

    Ensures your images come out just the way you want.

  • AF/MF switch on lens barrel

    Conveniently enables fast selection between autofocus or manual focus without having to access any menus.

  • Customizable focus hold button

    Locks focus when recomposing and can be assigned to other functions, such as eye AF, AF on, aperture preview, shot result preview, and bright monitoring.

  • Two eXtreme Dynamic linear motors

    Directly drives the lens's focus mechanism without intervening gears for precise, quiet operation that is ideal for movies as well as stills.

  • Internal focusing

    Only the middle groups of the optical system move to achieve focus, so the overall length of the lens does not change when focusing.

  • Fluorine front-element coating

    The front lens element features a fluorine coating that repels water, oil, and other contaminants, while making it easier to wipe off any contaminants or fingerprints that do become attached to the lens surface.

  • Dust- and moisture-resistant construction

    Enjoy extra protection and reliable operation in challenging environments. Shoot with confidence in light rain or windy conditions.

  • 0.59' minimum focusing distance

  • Accommodates 67mm filters

    amazing lens, lightweight small design

    One of the best lightweight lenses for the Sony Emount system. It's tack sharp and pairs well with my other prime lenses that I take to shoots. Im surprised it's not a GM series lens with the build quality and picture quality it produces on my A1.

    Better than Tamron 17-28mm

    I’m sure everyone who considers a wide angle from Sony is considering this lens or the tamron 17-28mm. I can tell you with 100% confidence this lens is the better option! Still wide enough for real estate and vlogging and the wide aperture helps with low light! Very sharp lens!

    Not sure if it is value for money.

    The lense has quite some features compared to my existing samyang f1.4 lense. But the pictures were comparatively better with the $250 samyang one. I missed the 14 days return window so cant do anything now but one thing that I wont regret is the size and weight. It's smaller and ligter than the cheaper lense. I am learning so I might be doing something wrong but that doesn't make my snaps by samyang any better.

    Great walk-around lens for hikes

    This was my main and only lens for a recent hiking trip to Sedona and the Grand Canyon. It's super fast so I knew that I could get the shot in any lighting situation and then zoom (crop) in post. I wanted a single no-fuss lens to handle the wide gorgeous stuff, the normal people posing in front of cool things stuff, and even some close-up and almost macro stuff. This lens delivered.

    The Best Vlogging Lens for Sony

    The 20mm f1.8 lens stays on my A7C 90% of the time for video. Whether I am vlogging or making travel videos, this lens is light, compact, a great focal length, and a 1.8 for evening content. I love this lens and it keeps my travel setup ultralight.
