# The Carl Zeiss 35mm f/2 Distagon, Pentax Mount (ZK) in 2026

*May 18, 2025 — Kasper Bergholt*

Some consider the Carl Zeiss 35mm f/2 Distagon the best 35mm lens made for Pentax mount (ZK).

It was discontinued in 2010 resulting in high prices for deadstock and lenses in mint condition especially in comparison to the same lens with Nikon or Canon mount, and they are rarely seen for sale on sites like MPB.

I got the lens after working with a Carl Zeiss Milvus 50mm f/2 makro-planar lens with a[*Nikon D3*](<https://bergholt.net/nikon>)for various projects (beginning with macro-photography of*tubes for a[Leben tube amplifier](<https://bergholt.net/tubes>).*

The Carl Zeiss Milvus 2/50 (makro-planar design) weighs in at 530 grams, the Zeiss 35mm f/2 (distagon design) is ‘only’ 570 grams.

Significantly heavier than my*[Pentax 77mm 1.8 limited](<https://bergholt.net/pentax>)*(270 grams), with a generally more solid feel. The focusing ring of the 35mm Zeiss is a lot tighter, and the throw is significantly longer compared to the Pentax 77mm 1.8.

Some compare the ZK mount family of lenses with older lenses produced by Zeiss for Hasselblad cameras.

If you’re considering getting one, keep in mind that it’s a fully manual-focus lens.
