| p.3 #8 · Sony Full Frame attack: (SR5) Three E-mount FF to come within 5 months! |
Anyway, the combo FF-NEX + Sonnar FE 35/2.8 has only 54.5 mm from the focal plane to the lens front, while the combo M camera + Biogon ZM 35/2.8 is 58.7mm.
Yep. It seems f2.8 designs will be ok for 35mm. It'll be interesting to see how large the rumored 55/1.8 is.
Since it's so small, it's entirely possible that the f2.8 Sonnar has a more symmetric design. Old symmetric lenses are rarely if ever faster than 2.8. The faster leica wides all have a more retrofocal design and are bigger. The throat size is only a limitation for fast and retrofocal designs(requiring large rear elements), i.e. it might not be possible to design a fullframe 50 1.2 for the E-mount. Symmetric wide lenses have a high incident angle not due to the small throat size, but by definition. Whether Sony can make small wide lenses has everything to do with whether...Show more →
Yeah, I'm assuming that Sony hasn't made any giant steps towards improving the sensor coping with high incident angles, and a 35/2.8 Sonnar doesn't change my view on that, because, as I mentioned, it is probably in the same design vein as the 24/1.8 and RX1 Sonnar.
I'm not too sure about that, the E24Z is a 7/8(group/elements) design while the FE35 is a 5/7
