A new source sent me the following info:
1) Sony is working on a feasibility study right now for a full frame Zeiss Tilt Shift Lens for A-mount. This may be an autofocus lens!
2) Also up for debate are two aps-c mirror A-mount telephoto lenses: 350mm f5.6 AF SAM and a 500mm f8 AF SAM lens.
3) From what i’ve heard the 400 f2.8 will not happen, but the 400 f4 has been sent to design.
Don’t know yet of the info is correct. Also in that case I hope trusted sources can confirm or deny this. Thanks!
P.S: In these days I am working on the new A-mount roadmap. Sources can send me info anonymously through he contact form you see on the right border of the website. Thanks!
