It can\'t physically be like that because of how extremely close to the sensor the RX1 35mm lens sits. This new lens may be loosely based on the RX1 lens but it is certainly modified greatly due to the rear element proximity to the sensor. There may also be a question as to whether the HUGE RX1 rear element would even go through the front of the mount!
Well, not necessarily again The importance isn\'t how close the glass is to the sensor, but at what angle the rays are allowed to land, with good image quality. If Zeiss can design the f/2.8 lens with a rear element which isn\'t as close (which was presumably needed to cancel some aberrations which won\'t be there on an f/2.8 lens), but lets the rays fall at the same angle, well, Bob\'s your uncle, eh?
Let\'s see. I think the 35/2.8 could hold some promise, image quality wise, but obviously the special look at f/2 will be gone forever, never to return.
Oh, I\'m sure the 35 2.8 will be a good lens - possibly great- but the design, strictly speaking, of the RX1 35 is different just from what we already know. The RX1 35 lens consists of 8 elements in 7 groups with 3 of those elements being aspherical (one of which being what Sony Zeiss call \"Advanced Aspherical\" whatever that means). The new FE 35 2.8 consists of 7 elements in 5 groups. We don\'t know about asphericals yet. Both are designated Sonnars. That\'s not to say Zeiss did not use the same or similar design principles but it\'s not going to be the same exact design just scaled down.
It\'s the rear element that is \"advanced aspherical.\" It is really complex:
