The Nikon 18.5mm is a 50mm f4.9 FF equivalent camera. The others you list are 40mm FF equivalent... A small but noticeable difference.


Reasons to get a V1 that I can see: When it was released, the other cameras did not yet exist? It is a Nikon, so a "natural" choice for a Nikon shooter? The Fuji with its odd CFA pattern makes for most RAW converters not getting the best results? The MFT cameras have a 4:3 aspect ratio, the Nikon 1 3:2? The AF implementation of the Nikon 1 series is really very good?

 

A 40mm is arguably a more versatile FOV than 50mm as a walk-around lens.

However, if 50mm equiv is really required then there is the Oly 25mm f1.8. It provides better FOV control (f3.6 FF equiv) while the total package size remains in the same ballpark.

 

Fuji CFA pattern is not an issue anymore, even with LR.

If the photos (very nice ones) shown are an indication, AF is definitely not a limiting factor. Even something like a Pany GF2 would be sufficient.
