Nikon 70-200/2.8S screening test

October 3, 2020 JimK 1 Comment

I received the Nikon 70-200mm f/2.8 S lens for Zx cameras yesterday. First impressions: About the same size as the 70-200mm f/2.8E, but noticeably lighter.

I’ve done a lot of testing of the focus bracketing (Fujifilm’s name for it), and focus-shift shooting (Nikon’s) on the GFX 50S, the GFX 100, the Z7 and the D850.

April 2, 2020 JimK 1 Comment

A reader asked me to test the new Nikon 20 mm f/1.8 against the 14-30 mm f/4 Nikkor S zoom when it’s set to 20 mm. Here’s my distant foliage test on the two. Here’s the scene, with both lenses wide open on a Nikon Z7:   Corner falloff is similar. Here’s the test protocol:… [Read More]

Sony 20/1.8 G, 20/1.8 Nikkor S sun stars

March 31, 2020 JimK 3 Comments

This is one of a series of posts comparing the Sony 20 mm f/1.8 G lens to the 20 mm f/1.8 Nikkor S. One of the things that photographer like to do with short lenses is make sun stars. It’s not hard. You stop your lens down as far as it will go, aim it… [Read More]
