NIKON NIKKOR Z 20mm f/1.8 S Ultra Wide Angle Fast Prime Lens for Nikon Z Mirrorless Cameras

Me parece un excelente lente, con gran luminosidad, muy buena construcción, de autoenfoque rápido y silencioso.

I did a lot of lens research after moving into the Z system (Z6ii) as I love to shoot the Milky Way. It was between this and the 14-24 2.8. Besides the cost difference, I loved the additional light that the 1.8 could bring. This lens also got great reviews everywhere, and after using it, I can see why. Even wide open at 1.8, I’m very happy with coma, ca, corners, etc. I was worried about focus by wire, and while I don’t love it, I’ve found the adjustment to be easier than expected. Results are light years beyond my crop sensor days. I would easily recommend this lens for anyone with similar interests.

I just bought both lenses to try for astrophotography and milky way photos. The Nikon z 20mm lens is very sharp and great for the stars. It is much lighter and smaller than the Sigma lens and can also be used for daytime landscapes. The pictures from the Sigma 14-24mm were comparable in sharpness for stars and low light. Benefit of Nikon Z lens 20mm is that it much smaller and lighter 1.2lb than the Sigma lens 2.5lb. Also, it takes a 77mm filter which is easier to find. The Sigma needs a huge filter if you can find one. Also, the Nikon Z lens fits in a camera bag easily. The Sigma doesnt. The Sigma lens is a huge lens and doesnt really fit in a camera bag and weighs as much as the Nikon Z6 ii camera itself. The benefit of the Sigma lens is that at 14mm it captures 25% more milky way and sky than the Nikon 20mm lens. You would have a hard time carrying the Sigma 14-24mm lens during the day without your arm getting tired. Also, the Sigma lens only fits on an FTZ adapter and the adapter is hard to put on the Z6 camera while its on a tripod. You have to take the camera off the tripod to put the adapter on and the Sigma lens on, which is a pain and can force you to re-polar align again if you use a star tracker. However, most pictures of milky way with the Z 20mm lens cut off part of the milky way. They seem to capture mainly the galactic core and not much else. The Sigma captures much more of the milky way and sky. So its a trade off between the 2 lenses. I am trying to decide which lens to keep and which lens to return. Tough choice.

Initially I was put off by the length of this lens, but it is giving me beautiful results. I threw it on my Z7 during lockdown, and the first image I took won a National comp, so very impressed with what it can produce. It is very sharp edge to edge, and at 1.8 has pleasing bokeh. This is the first 20mm prime I’ve owned, and I have to admit I can now understand what all the fuss it about. Highly recommended.

Good: Sufficient sharp; low weight; goes smooth on Z7 compared to other Nikon lenses made in China; auto focus (pin point) on stars works very good; seems to meet typical MTF spec; only very corners soft at 1.8 - 5.6; top half was not as sharp as bottom half (no problem , if you set AF Fine Tune=OFF and use single point on your subject you will be fine or stay > =F5.6 for landscapes ), 77mm filters, in case you need it; close focus is excellent from 2-3 inches to inf, which is very important for wide angle lenses; good color representation.

I read a lot of reviews before purchasing this lens. I have used it primarily for Milky Way photography. With the 1.8 it allows shorter timed shots which keeps the stars very sharp. The 20mm is just about perfect for capturing the Milky Way and foreground subjects.

My new go to wide angle. It performs beautifully for both landscapes and nightscapes. Learning how to photograph the Milky Way and this lens makes it simple.

Muy ligero y luminoso

Coupled to the Nikon Z7, the speed and sharpness are everything I expected.

Dentro de la serie Z, es de las mejores opciones para foto de arquitectura. Gran apertura y buen distancia focal. Para video, casi no tiene focus breathing, lo cual es muy bueno también
