I was wondering what people think about Nikon opening up the Z mount to third party lens manufacturers? Do you think it would help Nikon's bottom line if they sold more camera bodies while allowing the 3rd party lens manufacturers pick up the slack, especially with stiff competition and fewer camera sales than before? I feel like companies like Sigma, Tamron, Tokina and Samyang can fill lens gaps in the Z line-up quickly, while allowing Nikon to focus on the pro and prosumer core lenses for the system. For example Samyang has a full line-up of compact 2.8, 1.8 and 1.4 prime AF lenses for the Sony E mount, which I'm sure could be optimized to work on Z cameras. Tamron has lenses like the 17-28mm and 28-75mm 2.8 lenses also for the E mount that can give quickly give the Z 2.8 zoom options. I'm sure sooner or later these companies will backwards engineer the mount, but it'd be nice if there was some corporate support for an open mount policy. The Z mount is the widest and potentially the most flexible mount of any mirrorless system. What do you think Nikon should do?
