In addition to a new DX camera, Nikon is rumored to announce a new 24mm f/1.8 lens in 2015 – most likely in the January-February timeframe for the CES or CP+ shows. With a performance close to the f/1.4 versions and for a fraction of the price, the f/1.8 lenses have been a huge success for Nikon and it is not a surprise if they decided to expand their current f/1.8 line (20mm, 28mm, 35mm, 50mm, 85mm).
Nikon currently has four 24mm lenses: Nikkor AF-S 24mm f/1.4G ED, Nikkor AF 24mm f/2.8D, Nikkor AIS 24mm f/2.8 and Nikkor PC-E 24mm f/3.5D ED.
Sigma is also preparing to announce a new 24mm f/1.4 lens soon (they already have a 24mm f/1.8 lens).
