Sony FE 20mm f/1.8 G Full-Frame Large-Aperture Ultra-Wide Angle G Lens

This new addition to Sony’s Prime G Lenses is an ultra-wide 20mm that gives to edge-to-edge sharpness with a fast f/1.8 maximum aperture. The XD (Extreme Dynamic) Linear focus motors allow for smooth and quick focusing. It optical design employs two AA (Advanced Aspherical) elements and three ED (Extra-low Dispersion) glass elements that combine to accurately reproduce point light sources with high contrast. As a result you get crisp, clear images with minimal sagittal flaring of challenging subjects such as night scenes and starry skies. The lens’ lightweight design makes it ideal for videographers and vloggers, and perfectly suits a wide variety of scenarios like landscape, street, starry-nights, and environmental portraits. A special Nano Anti-reflective coating on lens elements suppresses reflections, flare and ghosting, while the fluorine coating on the front lens element repels water, oil, and other contaminants for sharp, clear images.

30mm Equivalent on APS-C Bodies

This lens weighs just 0.82 pounds and measures in at only 2.89 x 3.33 inches. It’s small size and lightweight design enhance mobility when used with compact E-mount Full-frame or APS-C camera bodies and is ideal for use on gimbals or accessory grips.

Beautiful, Natural-Looking Bokeh

The lens’ maximum f/1.8 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 areas out of the focal plane appear blurred. As expected from a G Lens, the Sony FE 20mm f/1.8 G lens delivers a smooth, natural-looking bokeh. A large f/1.8 aperture combined together with a 9-blade circular aperture mechanism and precise control over spherical aberration characteristics help achieve an amazing defocused background quality.

Advanced Optical Performance

At the heart, the Sony 20mm Prime G Lens uses two AA (Advanced Aspherical) elements and three ED (Extra-low Dispersion) glass elements. The Advanced Aspherical) elements help achieve high corner-to-corner resolution even with the narrow depth-of-field produced at the lens’s maximum f/1.8 aperture. On the other hand, the three ED (Extra-low Dispersion) glass elements virtually remove axial chromatic aberration and chromatic aberration to achieve significantly reduced flare and ghosting. This gives you high resolution images with maximum bokeh featuring precisely rendered edges with no fringing or unnatural coloration.

XD Linear Motors for Fast, Precise, Quiet Focusing

The FE 20mm f/1.8 G lens incorporates a precision internal focus mechanism consisting of two XD (extreme dynamic) Linear Motors that help deliver high-speed, smooth autofocusing. With new control algorithms, it is possible to smoothly drive the lens’s focus group achieving silent, low-vibration and continuous autofocus in both still and video modes.

Instant Auto/Manual Focus Selection

An AF/MF switch on the side of the lens lets you quickly switch between auto and manual focus modes for a faster and easier operation. Linear Response MF (manual focus) ensures that the focus ring responds directly and linearly to subtle control when focusing manually.

Aperture Ring with Switchable Click Stops

In addition to providing the fast, hands-on response required for still and videos, the Sony FE 20mm f/1.8 G lens’s aperture ring includes an on/off switch for its click stops. You can switch it on for tactile feedback when shooting stills or switch it off for silent control when shooting movies. The combination of quiet XD Linear Motors and the quiet operation available when the click stops are switched off is great for smooth, seamless aperture control when shooting movies or capturing events where noise must be minimized.

Sony FE 20mm f/1.8 G Full-frame Large-aperture Ultra-wide Angle G Lens

Sony FE 20mm f/1.8 G Full-Frame Large-Aperture Ultra-Wide Angle G Lens SKU: SEL20F18G

Rated 5 out of 5 by from fantastic for a G-series lens. I bought this lens about a month and and am so happy I did. It's sharp and has excellent color.

Rated 3 out of 5 by from great, but.... HI, i bought the lens for my camera. The only problem with this is that the inside of the lens shakes back and forth, so is this a manufacturing problem, or is this just a feature in the lens?

Rated 5 out of 5 by from Clearly an Amazing Lens - Street, Astro, Landscape This is a special little lens. I'm sure "little" will be in every review, but it is so strikingly compact, even sitting next to it's FE 24 F/1.4 GM sibling. It's just small! But, it really delivers, with focus speeds, sharp images edge to edge, incredible corners, especially for stars, and just a unique rendering quality. I really like this lens a lot.

Rated 5 out of 5 by from Wide, light and fast! This is the widest prime lens released so far by Sony. At f1.8 it can almost shoot in the dark. Autofocus is immediate. Close focusing is near-macro. It weighs less than a pound, so hand holding at slow shutter speeds is not a problem. Add to those features a very affordable price and you’ve got a Sony full frame prime lens worth owning!

Rated 5 out of 5 by from A really great lens Sony has been building its inventory of lenses for E-Mount cameras. We can now say that Sony has arrived with this lens. So... if you purchase an E-Mount, you should have what you need to shoot great photos.

Rated 5 out of 5 by from Very wide with minimal distortion! I’ve had the Sony 20/1.8 for a few weeks and like it so much I sold my 24/1.4gm because the 20mm is wider, lighter and just as accurate with even faster AF. Highly recommended.
Date published: 2020-03-24
Rated 5 out of 5 by from Sony crushed it! This lens is pretty much a G master. It’s not just super sharp with low distortion, it portrays the essence of the subject so well. It really brings the scene to life.
Date published: 2020-03-13
Rated 5 out of 5 by from Another WINNER! I've been shooting the 24mm F1.4 GM for few months and extremely impressed with the results this lens produces. however, I would prefer wider prime native lens, hence, the new 20mm F1.8 G. I bought this newly released 20mm F1.8 with the hopes that it will be my go to everyday lens; I have a feeling that it will be. This is by no means a full review but I wanted to see how it performs in close up situations so I snapped couple shots in my backyard; it certainly holds up to the hype. I'll be taking it out in the next couple of days to do some landscapes testing at Joshua Tree National Park (day & Astro tests). I have to say that Sony did it again, they delivered a "Tiny-but-Mighty" master piece with small size, light weight, silent autofocus, aperture ring, and super sharp just to mention few great features. Yes, it is expensive but worth every penny for me as I can travel much lighter going forward. Technical values for both shots taken with A7R-IV in RAW straight out of camera. The only thing I did is square crop them both then export from LR as small JPGs : The Rose: F/1.8 1/500 ISO 125 The Watch: F/5.6 1/100 ISO 125
