>>2655520I guess you are most likely right about this.
I just looked up the Fixed lens on the RX1. And it turns out it's completely different from other E-mount lenses.
This thing has glass elements built-in far deeper than the red ring, which is normally the boundary for interchangeable lenses in E-mount.
This 35mm f/2, looks so small on the surface, but it's actually much larger than the 35mm f/2.8.
