Did you notice that the Zeiss 24mm is a Sonnar instead of a Distagon/Biogon?

I reckon that everything faster than f/2 is a Sonnar.

SLRgear already has the review for 16-50mm lens

I've read the SLRgear review, and it looks like a nice lens: WR, sharp, good speed, and low to moderate distortion.
It's the lack of such a lens in Pentax land that has kept me away from the K-mount.

The new 35/1.4 ZE/ZF.2 is a Distagon.

FWIW, the MTFs are also available on the Sony JP homepage.

The Zeiss MTFs are not cross-comparable due to the different frequencies.

All the lens elements are much smaller than the diameter of the lenses. Sony didn't try to miniaturize that much. Looks like a standard diameter for all the lenses.

The lens cross section SEL50F1.8 looks very different to the SAL50F1.8. The MTFs wide open are better too. Can anyone explain what type of lens design is used?
