Note: None of these items are for sale. They are systematically used, stripped, cleaned, and benchmarked within my private rotation.
1. Meyer-Optik Görlitz Oreston 50mm f/1.8 (East Germany)
- Production Era: Circa 1972
- Optical Design: 6 elements in 4 groups (Modified Double-Gauss)
- Minimum Focus: 0.33m (Excellent close-up capabilities)
- Current Status: Glass fungus-free; light cleaning marks (haze) on the front element.
"Pronounced vignetting wide open; axial chromatic aberration completely clears up by f/2.8. Exceptional for moody portraits with organic flare and signature sharp-edged bokeh bubbles under strong rim-light."
2. Industar-61 L/Z 50mm f/2.8 (USSR "Star Bokeh")
- Production Era: 1985
- Optical Design: 4 elements in 3 groups (Tessar formula)
- Aperture Blades: 6 blades (Forms a distinct star shape between f/5.6 and f/8)
- Current Status: Clean glass. Features Soviet Lanthanum radioactive glass, providing a native subtle warm filter effect.
"Bitingly sharp across the frame. Due to the unique aperture geometry, it yields razor-sharp six-pointed starbursts on point light sources without needing a physical star filter on the thread."
3. Minolta MD Rokkor 45mm f/2 (Japan)
- Production Era: 1978
- Optical Design: 5 elements in 5 groups (Pancake profile)
- Current Status: Mint condition, pristine elements, clicky aperture ring.
"The ultimate ultra-lightweight street-shooting lens. Renders with Minolta's signature rich, warm contrast. Exceptional rendering of deep blues and forest greens on color negative stocks."
