Sharp, fast, great focusing.
Style: ‘w/ 20mm G’
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.

Compact and Sharp!!
Style: ‘w/ 20mm G’
I struggled for several days trying to decide between the Sony 24mm f1.4 GM and the Sony 20mm f1.8. Sharpness is very important and size/weight is a major consideration. I kept reading reviews about how sharp the 20mm f1.8 is. I finally pulled the trigger on it and WOW...it exceeded my expectations!!! Great sharpness and clarity at f1.8, f2 and f4 (those are all I tested). On my 61 mp full frame sensor, I can easily crop to 24 or 28mm equivalent with excellent results. Very happy with my purchase!

10/10 Perfect AF, small, lightweight, sharp at 1.8, smooth bokeh, no CA, nice to have aperture dial.
Style: ‘w/ 20mm G’
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.

A GM Lens at a G Price (Really!)
Style: ‘w/ 20mm G’
Really, there is nothing I can add to all the professional reviews out there on YouTube -- this lens is simply outstanding and I am so happy that I bought it. I'm using it on a crop sensor camera, which gives a 30mm FF equivalent and it is so good that I try to use it for everything from wildflower close-ups to landscapes. In addition to the outstanding optical performance, the aperture ring, AF/MF switch, and focus hold button add to the convenience and make it a pleasure to use.

My new favorite lens
Style: ‘w/ 20mm G’
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.

The perfect vlogging lens without distortions

Went through a lot of lenses to find this one!
Style: ‘w/ 20mm G’
I have experimented with a lot of 18-20mm lenses on my Sony a7riii. I've had the Zeiss Batis 18mm f/2.8, Samyang 18mm f/2.8, Sigma 20mm, and Tamron 20mm. Up to that point the sharpest lens was one of the cheapest, the Tamron 20mm lens, but it had a lot of distortion. Once I discovered The Sony 20mm, my search was over. One of the sharpest lenses I've used with very little distortion. Plus, it was great for video work. It's only drawback was some focus breathing, but I'm more of a stills photographer than a video guy. Plus, it is f/1.8 and not a huge lens. This compliments my Sony 50mm G lens quite well. On short trips when I'm packing extremely light, I will take this 20mm lens, along with the 50 g lens, and the Sigma 90mm lens (great traveling kit). I prefer primes. But I do use the Tamron 28-75 G2 and 70-180 lenses for event work. And my Samyang 135mm and Sigma 85mm f/1.4 for portraits and more indoor work. But you can't go wrong with The Sony 20mm f/1.8. Well worth it!

Price/Performance/Weight
Style: ‘w/ 20mm G’
With my iPhone, I can take many good pictures already without carrying a camera and lenses. And I'm an amateur photographer. This is why my first criterion is pricing. I do not want to spend more than $700 for the lens. The pricing for the lens is on the borderline for me. The picture quality and the ultra-wide angle view convinced me to pay more. The lens weighs 13.2 ounces (<1 pound), which is acceptable. This is important, especially when it comes to international travel. And I do not want to carry a heavy lens on my neck. This is a great lens. Compared to the pictures taken with my iPhone versus with this ultra-wide angle lens, I'm happy with it. The pictures attached are raw pictures without edits. It does not work well at night, but I'm OK with it—money well spent.
