Ultra-Wide Portable Prime
Presenting an ultra-wide field of view, the Sony FE 20mm f/1.8 G is a sleek and wide-eyed prime lens characterized by its portability, advanced optical design, and intuitive handling. It's an ideal companion for a range of subjects, from architecture and interiors to landscape to vlogging, and the sleek size makes it a go-to wide-angle option for everyday and travel shooting.
G Lens Series
  • Two AA (Advanced Aspherical) elements help to greatly reduce distortion and spherical aberrations in order to accurately render scenes with a high degree of sharpness.
  • Three extra-low dispersion elements reduce color fringing and chromatic aberrations for improved clarity and color accuracy.
  • Nano AR Coating has been applied to minimize surface reflections, flare, and ghosting for increased contrast and color rendering in strong lighting conditions.
  • Bright f/1.8 maximum aperture suits working in difficult lighting conditions and helps to maintain a relatively compact form factor.
  • Rounded nine-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
Autofocus and Handling
  • Dual XD Linear Motor system, along with an internal focusing design, provides quick, quiet, and precise autofocus performance that suits both photo and video applications.
  • Linear Response manual focus control offers more natural handling and an AF/MF switch is located on the lens barrel for tactile control over this setting.
  • Customizable focus hold buttons are present on the lens barrel for intuitive tactile control and rapid access to select settings.
  • Physical aperture ring can be de-clicked for smooth, silent aperture switching to benefit video applications.
  • Despite being an ultra-wide prime, the sleek design still accepts front 67mm threaded filters for easier creative control.
Compact, Portable Design
  • Weighing just 12.3 oz, this sleek lens is an ideal choice for vlogging and walk-around shooting applications, and makes a great companion to APS-C-format cameras and working with gimbals or accessory grips.
  • Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.
  • Fluorine-coated front element resists dust, moisture, and fingerprints and is easy to clean.

Sony FE 20mm f/1.8 G Reviews

Excellent lens!

I bought this lens last year after acquiring the my A7C. The 20mm f1.8 is outstanding particular for indoor limited light use. I personally dislike using flashes under any circumstances as it proves difficult to adjust (for me) even in post. This lens gives me the freedom to use it for limited light situations and still achieve great results.

Great Lens for Astrophotography, Video, and Blogging

By Paulo

I bought this lens mainly because I needed a Fast Wide Angle Lens (Faster than f/2.8) with minimal distortion and chromatic aberration. First, the optics of this lens are comparable to the Sony FE 24mm f/1.4 GM. Second, the angle of view seems to be appropriate for most Wide Angle needs but it is particularly well-suited for those who want a blogging lens - since this one gives you a few extra degrees of view where you can comfortably fit your face. Third, the Autofocus is fast and accurate, except under very special circumstances (like low light). Forth, I love this lens for those situations when I need minimal weight (i.e. when I'm hiking in high altitudes and every extra pound feels like a ton). For this reason, it is also a great lens to be used on a Gimbal or other kind of support devices used by video creators and bloggers. Fifth, I really appreciate its capability to get very close thanks to its minimum focusing distance. Finally, the Bokeh is not as 'creamy' as the Sony FE 24mm f/1.4 GM but it is absolutely satisfying nevertheless. One minor disappointment about this lens relates to having a very noticeable 'lens breathing' effect. So if you are into pulling focus on videos - you will need to deal with this minor limitation. This is one of my favorite Sony Lenses, I own and use almost all of the GM series, except for the Super Telephoto ones. I will soon travel to Bolivia's Uyuni Salt Flats where I will be able to test this lens for Low-Light and Astrophotography.

This lens work perfectly on the a7Rv. AF is very fast and accurate. Tracking and subject recognition work very well, even in low light (e.g. dive bar concerts). Focus is nailed even at the edges and corners. Distortion, aberrations, and flare are controlled so well as to make them irrelevant.

Heavy vignetting

Very heavy vignetting with cold color cast in the vignettes. Vignetting does not completely go away after lens correction in lightroom. Distortion is not good either. In the past, I have been using a Sigma 20mm f/1.4 for Nikon F. In comparison, I was very disappointed in this sony G.

Used for Astrophotography

Solid construction, and the fast aperture makes for a great astro lens. I've shot some fun stuff with it so far. It's built solid with smooth aperture and focusing rings, and the balance is there. I like the focal length- I have a 14 that feels overwhelming, but a 35 isn't wide enough. The 20mm rides the fence nicely. Be warned: when the lens isn't on the camera, there is an internal element that shifts slightly. When attached to the camera, it does not do that, but if you're holding the lens in your hand, you may feel the imbalance. So far so good!

Many prime lens users appreciate the simplicity, performance and lighter weight of a prime lens as compared to a bulkier, stabilized/zoom lens. That's my guess.

Could it be mounted in a not full frame as the Alpha 6600. And what focal length would result?
Asked by: Marcelo
I am using it with the a6600 and it’s a fantastic combination. It balances quite nicely and feels great in the hand. The autofocus is lightning fast and love the manual aperture ring.

Would this lens be overkill for a Sony a6000? Looking for a solid ultra wide angle lens for the a6000 but I can't determine whether this has features that I won't be able to take advantage of on my camera.
Asked by: Marc
This lens is quite basic with manual aperture selection. There is no lens stabilization. The effective focal length will be 30mm on the APS-C sensor of the a6000. I have used this lens on both an A7 and A7R4 so I can't comment on actual results on the a6000. That said, I have been very happy with the FE 20mm f/1.8 G, it is lightweight and delivers great results in low light.
