Such a great lens!!! Amazing amount of light and great for night shots with long exposure times and great aperture control.

Very fast, relatively sharp lens with minimal defraction, used specifically for aurora and astro for a season and pretty happy with it. Very comparable to the sony 20mm 1.8, but takes up about twice the space in your camera bag. Over all a pretty good lens for the money.

Just received the lens so no time for full evaluation. I have had the HSM 20mm for Canon and have used on Sont A7r4 with Metabones adapter. I have enjoyed the HSM lens for use in low light but used sparingly due to weight and fear of damaging front element during casual use. I bought the DG,DN lens because I figured I would get to use it more often but did not consider the improvement in photo IQ or video performance. I saw a couple of reviews comparing Sony 1.8 stating the Sony was a little sharper and I was not expecting a large increase in the IQ over old HSM. I think I was wrong. So far with only about 100 test images, this lens appears to be a definite improvement over the HSM. New Lens also much better for video since no adapter needed. Very fast, accurate ...

Very fast, accurate focusing improves IQ as well. Very impressed. Very happy so far. Plan to use new lens a lot especially in low light. Kudos to B&H for super-fast delivery!!
Other than vignetting, this lens is a monumental step forward in 20mm lens technology! I also wish the lens hood were a little tiny bit smaller in diameter so it wouldn't be such a tight squeeze in my custom fit case previously configured to hold six A7R Mark IVa cameras and one A1, all with prime lenses mounted and with grips ready to grab and start shooting, all in a smaller case than a typical big backpack, small enough to fit into an ordinary fold up wagon and leave room for a basket of flowers and other props, plus lights!
Outstanding optical quality and a range of invaluable features –The ultimate astrophotography lens from the 20mm F1.4
Compact and solid lens lives up with Sigma reputations.
This lens is incredible. Look beautiful ?? image quality wow... Very sharp, I like color sigma. 20mm perfect for me and with my a7IV and APSC crop, it's almost 35mm
There haven't been a lot of reviews yet of the newer DG DN 20mm f1.4 Art lens for L mount. Yes it is expensive, but matches Lumix full frame cameras perfectly. I am a regular B&H customer, but this lens was sourced here i n Canada.The 20mm with the ridge for an astrophotography dew heater is so good as to be a value proposition. It's sharp wide open, but I chose a test sample image taken @ f2.If for architecture, such wide lenses must be held dead level to prevent vertical lines converging. The 24mm lens in the series is an option, with all the same features less the heater ridge.
This lens is well built, sharp, affordable, and so very versatile! You can use this for landscape, Astral, real estate, wedding groups, indoor family lifestyle, and so much more. It's great in low light, so perfect for situations like a wedding where you may not be permitted to bring lighting, it can focus anywhere from 4 inches from a subject, or it can capture an entire room. Focusing is fast, faster for sure than sony 1.8 primes. You really can't go wrong with this. I can see this lens being on my camera pretty often!
