Hoya's premium enlarging lens — the Super EL 50mm for quality 35mm printing.
The Hoya Super EL 50mm f/2.8 is an enlarging lens from Hoya (primarily known for optical filters and camera lenses) in their Super EL enlarger lens series. Hoya produced enlarger lenses as part of their broader optical manufacturing business in Japan.
The lens provides 50mm at f/2.8 with Hoya's Super EL multi-element formula for 35mm negative projection, with standard enlarger mounting thread.
Hoya's Super EL lenses applied multi-element design to the enlarger market for improved flat-field performance over basic Tessar-type designs. The Super EL branding indicated an upgraded specification within Hoya's enlarger range.
Check element clarity and Hoya coating condition. Test aperture blade operation. Verify mounting thread.
