Minimum Focus Distance


The Nikkor 20mm f1.8G ED is an ultra wide prime lens 20mm is a very short focal length with an angle of view of 94 degrees on a FX-body.

On a DX-body the lens is like a 30mm with a 70 degree angle of view.

I like to use this lens 50/50 with my FX and DX camera that I use on a day to day basis, For my choice of photography I’m always gonna use FX and DX camera mainly because of usability of my lenses, and also to have a second camera body.

Advantages of this 20mm lens, in my opinion.

This ultra-wide 20mm lens is good to capture:

landscapes and architecture.

wedding – parties.

Close focusing to 0.66 feet

group shots.



Minimum Focus Distance: 0.66 ft. (0.2m) almost macro.

This is one of my favorite lens to use you can do so many thing with this lens, I never go out on a photoshoot without taking this lens with my, this lens is very sharp and the colors are good also, this lens can also focus very close to your subject, almost macro the shooting possibilities are nearly endless with this lens.

lens distortion

Next two pictures were captured in RAW and then converted to JPEG with out any photo editing so the are straight out of the camera, but the brick wall is not so straight, this lens almost don’t have any distortion

Bokeh test

This lens create great bokeh effect but your subject need be very close to you because of the ultra-wide angle, but that is okay because of the Minimum Focus Distance: 0.66 ft. (20cm) you can focus very close to your subject.

Nikon 20mm on FX vs DX camera

My Nikon camera is FX – full frame and I can also use DX crop on it, here I’m using the Nikon 20mm on FX and DX crop just to give you an idea of the difference.

Nikon D810 in FX mode = 20mm


Nikon D810 in DX mode = 30mm


 Downtown photography

This lens is much more versatile than 50mm lenses that I have for downtown photography, but for cityscape photography I like the 50mm and the 85mm lens more.

Nikon D810 – 20mm f/4.5 / ISO 220 – 1/100s


Nikon D810 – 20mm f/4.5 / ISO 64 – 1/1600s


Landscape photography

In my opinion i think this lens is to wide on FX body for landscape photography unless you are gonna crop the photo to 16×9 or 21×9 than it can look good

Sometimes this lens back focus, but that have something to do with ultra-wide view that you get with this lens. With this ultra-wide view there is a lot more to focus on for the camera.
