maybe i'm slow, but the 1 series lenses sure look smaller to me. much smaller.

you are correct. where it's most noticeable, is when comparing the nikon 35mm f1.4 G to the 32mm f1.2. both employ nikon's newest SWM and Nano coating technologies.

nikon 35mm f1.4G

filter size: 67mm

approx size: 83.1mm x 89.4mm

weight: 601g


nikon 32mm f1.2

ilter size: 52mm

approx size: 65.5mm x 47.0mm

weight: 235g

while in general it's correct that there are no magical size/weight advantages to the optical designs, except for those caveats already given, there is often a difference in the size and weight of the lens chassis due to ergonomics and/or performance considerations. it would be equally false to omit this. however the longer the focal length, the smaller the differences in the chassis which hold the optics.

fortunately for those more concerned about FOV than DOF, the N1 has other advantages which allow for a smaller focal length in the first place.
