Re: RX1Rii users: does the ZX1 look like an upgrade?

I know they're not identical lenses, but they're both Zeiss-branded full-frame 35mm f/2 lenses. Why should a lens be developed to suit a particular sensor? None of the Sony RX or Alpha lenses were developed for one, specific sensor.

This one is different. Fixed lenses are designed differently than interchangeable. This one is optimized for the sensor.

In what way? What is there about this particular sensor that the lens needs to be optimised for? What does it do that the RX1RII lens does not?

Well, according to the original marketing materials the 35mm/F2 lens was designed specifically for the RX1. Even if you took it of the camera body, you wouldn’t be able to use it on a regular FE camera.

With fixed lenses the mount can be optimized: The lens can be mounted with greater precision and much closer to the sensor – even with no gap – allowing for quite different lens designs as to how the lens guides the light to the sensor.

There’s nothing new to this and it’s definitely not a ZX1-only feature. Fixed lens legacy cameras such as the Sony R1 and Lecia Digilux 2 had the same kind of optimization, too, as do the Leica Q series.
