By some considered as the best of 35mm lenses made for Pentax mount (ZK), discontinued in 2010 resulting in rather high prices (especially in comparison to the same lens with Nikon or Canon mount.
I got the 35mm f/2 after having worked with a Carl Zeiss Milvus 50mm f/2 macro with a Nikon D3 for various projects.
The Carl Zeiss Milvus 2/50 (makro-planar design) weighs in at 730 grams, the Zeiss 35mm f/2 (distagon design) is ‘only’ 570 grams.
Significantly heavier than my Pentax 77mm 1.8 limited (270 grams) with general more solid feel to it. The focusing ring of the 35mm Zeiss is a lot tighter and the throw a lot longer as compared to the 77mm 1.8 Pentax.
Some compare the ZK mount family of lenses with older lenses produced by Zeiss for Hasselblad cameras.
