The Nikon J5 is the newest in Nikon's 1 series mirrorless camera line and is the first in the series to offer 20MP resolution. (Note: the first Nikon 1 cameras had 10MP, while the most recent, the V3, had 18MP resolution). Compared to APS-C sensors with about 23.5 x 15.6 mm and Micro-Four-Third cameras with 17 x 13 mm, the J5 has a smaller sensor at 13.2 x 8.8 mm, Nikon’s CX format. The crop factor is nearly 1:2.7 which means that the “effective” (defined as the 35mm format equivalent) focal length of the kit lens (1 Nikkor 10-30mm f/3.5-5.6 VR) is about 27-81 mm. The camera has a very slim and compact design, which allows for easy transport and usage, similar to a compact camera.
