Which is better, Nikon fm2 or contax g 1? ?

FM2 and G 1 are not comparable. One is SLR structure, and the other is paraxial structure. There are great differences between framing and shooting methods. The design and structure of SLR lens and paraxial lens are completely different, and the charm of photos is also completely different. Automatic non-automatic is not the difference between paraxial and SLR, but the way of framing. WYSIWYG SLR framing, sideline needs more thinking and calculation. In pursuit of film production, you choose SLR, and in pursuit of photography enjoyment and technical improvement, you choose sideline. Leica has a history of 100 years, and the number of lenses adds up to dozens, which is not a fraction of Nikon lenses. But can Nikon shake Leica's position? Obviously not. Therefore, it is of great significance to talk about lens support for cameras with different structures.
