I don't get why they release so many large lenses

And why is the Distagon 35/1.4 FE ZA so much larger than the Distagon 35/1.4 ZM ?

The Distagon 35mm f1.4 is a typical Sony/Zeiss lens, with AF and more "modern" approach, the Sony Zeiss lenses usually have little in common with the traditional or other Zeiss lenses. The ZM is a more classic design, and MF.
