This hardly is the perfect list and I haven't really planned this setup but this is what I've got ( I just wanted to list them
). And almost all were bargains
1. S-M-C Takumar 4.5/20mm
2. Vivitar (Komine) Close Focus 2/28mm (bought cheap and converted from FD to M42)
Super-Tak 3.5/28mm (bought cheap as defective and repaired)
3. Auto-Tak 3.5/35mm (bought cheap as defective and repaired)
Super-Tak 2/35mm
4. Super-Tak 1.8/55mm
SMC Tak 1.4/50mm (bought cheap as defective and repaired)
M39(M42) Helios 44 2/58mm
M42 CZJ Biotar 2/58mm
5. M42 CZJ Biometar 2.8/80mm
M42 Cyclop 1.5/85mm (no aperture, so not very versatile. Bought together with Russian night vision device which I later sold so basically this was free)
6. M42 Meyer Optik Görlitz Orestor 2.8/135mm
7. PK Vivitar (Komine) 4.5/80-200mm (Actually have two of these. One with 58 and one with 62mm filter thread. The bigger is better.)
8. Canon L 2.8/300mm (converted from FD to PK)
For 1-3 I also have a plastic PK-A Cosina 3.5-4.5/19-35mm which I like surprisingly much
