after 2years of use…. i still one best lens i’ve ever had, only beaten by the nikkor 32mm f1.2
the lens is made of light materials and is therefore a light lens. The build quality of the lens is very good. The Nikon 1 system is known for it’s incredible fast and accurate focus, and the 18.5mm f/1.8 was no exception. I’m impressed with the output of this lens, wide open and stopped down. The 1.8 aperture lets you isolate the subject from the background better than the kit zoom. Set your aperture to f/1.8, then bring the flower petals into crystal-clear focus while the surroundings fade into a soft, beautifully blurred texture
This lens is a was not designed for macro work, just 0.12x magnification. at full aperture, this standard lens delivers high sharpness, even in comparison with standard lenses on SLR cameras. Almost all lenses show some form of color-fringing when shooting back-lit subjects, especially when used wide-open. The 18.5mm 1-Nikkor is no exception. Flare was generally well controlled and only noticeable when the sun was in the frame.
i would say with nikon1 and 18.5mm are able beat most old highend film cameras. the grain’y look of nikon 1 sensor makes best “digital film-look camera”
The 1 Nikkor 18.5mm f/1.8 is a nice prime lens that delivers very high sharpness. The 18.5mm f/1.8 1-Nikkor lens is a welcome addition to my Nikon 1 kit. It’s small, light, and very sharp. Nikon has done a great job delivering a lens that can be used in low-light conditions with the 1-series cameras.for this price point –> unbeatable!
