Of course, the weight would be higher. It is only 115 grams now. A Canon Ef 35mm f2 weighs twice that much, a more modern Canon EF 35mm f2 IS USM even 3 times as much.

 

So of course, the lens is light. Not the cause of the system, but the cause of the lens itself. 

 

You can't compare with a 42.5mm lens though, as the aperture of a 42.5mm f1.2 lens is 35.4mm, from a 15mm f1 lens only 15mm ... Again, regardless the technical look at things, it should be a nice little street photography lens.

 

Don't know. But the Voigtlander 17.5mm f0.95 looks quite larger. I guess an AF version would be larger.
