One of the first vintage lenses that I bought - and the first for many other photographers. Get one if you don’t have it yet. It’s cheap but fast and quite sharp at f/8. It’s best known for its bokeh.
A tiny and cheap lens that is better than you might expect on first glance

There are different varieties of this excellent lens. It’s actually the first vintage lens that I bought and I love it. The version with T* coating is supposed to be even better than the older copies like mine.

I’ll admit that I rarely use this lens. It’s quite soft, and sadly doesn’t bring more details than, e.g., its smaller counterpart, the MTO 500mm f/8.

This Zeiss lens gives you an extra reach if you need long focal lengths. I would rate it as fairly sharp but not quite at the level of the Zeiss 135mm f/3.5.

I can’t praise enough this camera. A foldable 6x9 medium-format jewel. I was extremely lucky to have found a cheap copy of it in excellent condition.

My favourite camera ever - and I’ve used many!
Asahi Pentax 6x7 MLU, TTL
Sharp and fast, excellent lens. It’s a must-have if you have the Pentax 6x7 camera.
If I need to go tele, this is undoubtedly my choice. It’s an excellent tool, standing out from pretty much any mirror lens. It has surprisingly good microcontrast and outperforms the others in its range.
