Our take on the Nikon 18.5mm f/1.8 1 Nikkor Lens

by Woody Sherman

One of the things every experienced photographer knows: Unless you have full control of the lighting situation, you'll want more light way more often than you'll want less of it. A lens that delivers plenty of photons to your image sensor is a good thing to have. This very bright, 50mm-equivalent "normal" focal length lens is designed to get you great results and creamy defocused backgrounds in situations where using a flash will disrupt the flow of events. The first time you see the mood and atmosphere that comes from shooting in natural, subdued light with a lens like this, you'll know you want to use it more.

great lens

Written By yawnmower1, new york city on Saturday, June 21, 2014
Crutchfield Customer Review (What's this?)
A really great lens from Nikon for its Series 1 line of cameras. The kit lenses are quite good (10-30mm and 30-110mm) and probably all that one would need. But this lens is a great addition. Equivalent to a 50mm lens in std 35mm cameras, it makes a great portrait lens with its beautiful bokeh effect. Great value even at full price, but fantastic value on sale. Nikon made a real winner with this line of lenses and cameras.
Fits J1, J2, J3 About the size of the kit lens 10-30mm Beautiful clarity and bokeh effect lightweight

Great lens

Purchased this lens for my Nikon J1, and it really put the kit lens to shame. Pictures turned out very crisp with the perfect background blur.
