Sony FE 20mm F1.8 G Full-frame Large-aperture Ultra-wide Angle G Lens

This ultra-wide 20mm prime G Lens offers outstanding corner-to-corner sharpness with a fast F1.8 max. aperture, making it ideal for a wide variety of scenarios like landscape, street, starry-nights and environmental portraits. Furthermore, the XD (Extreme Dynamic) Linear focus motorstrack focus flawlessly. The features and lightweight design make this lens ideal for videographers and vloggers as well.

Features

bokeh

AA ED

Advanced Optical Performance

A state-of-the-art optical design with two AA (advanced aspherical) elements and three ED (Extra-low Dispersion) glass elements accurately reproduces point light sources with high contrast and an absolute minimum of sagittal flare for crisp, clear images of challenging subjects such as night scenes and starry skies.The Nano AR coating suppresses reflections, flare and ghosting, while the fluorine coating on the front lens element repels water, oil, and other contaminantsfor sharp,clear images.

Beautiful, natural - looking bokeh

The deep, beautiful bokeh available with a max. F1.8 aperture is enhanced by a 9-blade circular aperture mechanism and precise control of spherical aberration characteristics that influence the defocused background quality. The FE 20mm F1.8 G lens delivers the type of smooth, natural-looking bokeh that discerning users have come to expect from a G Lens.

Two A A ( Advanced Aspherical) lens element

The 20mm F1.8G lens employs two precision AA (Advanced Aspherical) elements to maximize resolution and effectively compensates for field curvature and astigmatism that can be problematic in wide-angle lenses, achieving high corner-to-corner resolution even with the narrow depth-of-field produced at the lens’s maximum F1.8 aperture.

nano coating

Three ED glass elements

Three ED (Extra-low Dispersion) glass elements significantly reducing flare and ghostingby taking axial chromatic aberration and chromatic aberration(due to differences in magnification)out of the picture. Resolution and bokeh is maximized while leaving precisely rendered edges with no fringing or unnatural colorationright out to the image edges.

F1. 8 max aperture

The F1.8max aperture maintains exposure and depth of field, allowing you to isolate your subject from the foreground and background with amazing light gathering capabilities when shooting wide open. When changing your aperture to defocus the background, the areasout of the focal plane appear blurred. This ‘bokeh’ effect of the blurred background is enhanced with circular aperture blades used in this lens.

XD Linear Motors for fast, precise, quiet focusing

The FE 20mm F1.8 G lens incorporates a precision internal focus mechanismconsisting of two XD (extreme dynamic) Linear Motors that easily keep up with the high-speed capabilities of today’s most advanced camera bodies, taking advantage of their full autofocus speed, precision, and tracking potential to capture the most dynamic subjects. New control algorithms make it possible to drive the lens’s focus group smoothly and without delays for responsive, silent, low-vibration and continuous autofocusin both still and video modes.

Nano AR coating suppresses reflections, flare and ghosting

Flare and ghosting are often hard to avoid when shooting landscapes or outdoor scenes in strong sunlight with a wide-angle lens. Sony’s original Nano AR Coating technology effectively suppresses internal reflections so that high-contrast, clear images can be captured even in difficult light.

Compact, lightweight design

This lens weighs just 0.82lb. (373g) and measures in at only 2.89” x 3.33“ (73.5 x 84.7 mm). It’s small size and light weight enhance mobility when used with compact E-mount Full-frame or APS-C bodies and make up a well-balanced system that is ideal for use on gimbals or accessory grips.

30mm equivalent on APS-C bodies

The FE 20mm F1.8 G lens is highly recommended for APS-C as well as full-frame users.Itbalances well on smaller APS-C format bodies, providing a very useful wide-angle focal length of 30mm (full-frame format equivalent). 30mm is great for taking snapshots around town, shooting scenery while hiking or mountain climbing, and much more.

Aperture ring with switchable click stops

In addition to providing the fast, hands-on response required for still and moviemaking applications, the FE 20mm F1.8 G lens’saperture ring includes a switch that turns its click stops on or off: ON for tactile feedback when shooting stills, or OFF for silent control when shooting movies. The combination of quiet XD Linear Motors and the quiet operation available when the click stops are off is not only great for smooth, seamless aperture control when shooting movies, but also for shooting theater, concerts, and events where noise must be minimized.

Features

Customizable multi-function focus hold button

The focus hold button not only performs its primary function to lock focus when recomposing but can be customized via the camera body menu settings to a number of other functions depending on your needs. In addition to Focus Hold, these custom functions include: Eye AF, AF On, Aperture Preview, Shot Result Preview or Bright Monitoring.

Instant auto/manual focus selection

Instantly and quickly switch between auto and manual focus via an AF/MF switch on the side of the lens. This makes operation faster and easier as you let the camera and lens focus for you or decide to take control and manually focus on the precise point you choose.

Natural, linear manual focus response

Linear Response MF (manual focus) ensures that the focus ring responds directly and linearly to subtle control when focusing manually. Focus ring rotation translates directly to a corresponding change in focus, so control is feels immediate and precise in both still and movie modes.

Dust and moisture resistant1 for robust reliability

The dust and moisture resistance1 design make this lens appropriate for heavy-duty outdoor use, especially when combined with a camera that employs weather resistant measures.

    5.0 out of 5 stars 10/10 Perfect AF, small, lightweight, sharp at 1.8, smooth bokeh, no CA, nice to have aperture dial.
    Reviewed in the United States on July 14, 2020
    If you're looking for a fast wide angle prime for Sony FE and are on a budget, look no more.
    I'm very happy with this lens.

    It's small and lightweight. It feels solidly built.
    Optics are as perfect as they can be in this year of 2020.
    Zero chromatic aberration on my a7iii using Capture One Pro 12.
    Shooting stars I can see a TINY bit of CA, but not enough to bother me one iota.
    Auto focus is fast and accurate, basically perfect for both still and video on my a7iii.
    Focus transitions are smooth and little focus breathing.
    I used to use, and still do somewhat, modified Nikkor primes on canon cameras and got used to having an aperture dial. It's really nice to have. I've accidentally bumped it from 1.8 to 2 or 2.5 in my lens pouch, and that's messed up a shot or two, but it's a quick fix if you're paying attention and you can always put it on A and control via camera. When it's on A it's locked in place and isn't going anywhere. For me I like it.

    The hype for this lens is real. Sony knocked it out of the park imo.
    I was looking to get a wide angle prime but didn't want to dish out the money for the 24 1.4 GM.
    I'm very pleased with my 20mm. 10/10 Thanks Sony.

    5.0 out of 5 stars Sharp, fast, great focusing.
    Reviewed in the United States on September 30, 2020
    I was hesitant on the price of this lens.
    For much less I could get a slightly slower lens from other manufacturers but I chose to bite the bullet and go for the best quality.
    I am very happy with this decision. The fast lens f 1.8 lens is a great fit for me because I shoot so many pictures in the dark and low light environments. The picture quality is superb wide open and definitely sharp enough for the pictures that I take.

    FOCUSING: This new method of focus driving is far superior to anything else that I have tried.
    Nothing that I have beats it in speed, accuracy and volume.
    That's right, volume. This lens is nearly silent which is a huge plus for hybrid photo/video shooters.

    With that there are negatives:
    This lens is physically larger than my other wide angle lenses (28mm f 2.,8) but that is due to the amount of high quality fast glass in this lens. It is totally worth the weight to me, but if you are hiking around with it and don't need the maximum aperture of f 1.8 I'd go with a lightweight compact lens.
    I've had my concerns with the lens being damaged while it is powered off. You can feel the assemblies moving around under their own weight inside the lens. I am slightly worried about a large impact causing damage to the lens. I have not heard any other people reporting this as an issue, so I assume I am just worrying for no reason.

    Conclusion: I'd buy this lens again if I had to. This is by far my favorite wide angle lens that I have tried yet.
    I'd go for it over the 24mm GM if you're deciding between the two, the differences are almost meaningless when not compared back to back.

    5.0 out of 5 stars My new favorite lens
    Reviewed in the United States on March 14, 2020
    Obviously you can't use a wide-angle lens for everything, but this lens is super versatile and fun. I am amazed at how close you can get to an object and still get the lens to focus. Focus is fast and precise, vignetting is not bad as far as I am concerned, in fact, it seems awesome even at 1.8. Image clarity is very good. The aperture ring works great with a switch to turn on and off the detent. No stabilization on this lens, but with camera stabilization, do you really need it?
    A few days later, adding to this. I really like the different perspectives you get from this lens. It amazes me how close I have to get to what I am shooting to get it proportion. Because I have been shooting some large outdoor sculptures lately, it has become more of an up-close and personal type of lens. It should be great for real estate, abstract stuff, scenery and landscapes as you can get so much of what you are shooting in lens, while still being reasonably close.
    As a side note, I just checked and the lens correction file is already loaded in Lightroom for this lens. It was not showing in Photoshop yet, I am guessing they will add it in an update very soon though.
