Fujinon TS 300mm f/8

Fujinon TS 300mm f/8 is the Telephoto Super LF design at 300mm — refined T-series variant with larger image circle. Covers 5×7 generously where the standard T 300 only covers 4×5 with limited movements.

Key features

• Mount: Copal 1 shutter (1s to 1/400, X-sync at all speeds)
• Focal length: 300mm (effective)
• Maximum aperture: f/8
• Image circle: ~220mm at f/22 — covers 4×5 with generous movements; covers 5×7 tightly
• Optical formula: Telephoto (asymmetric, refined for larger IC)
• Multi-coating standard

Use case + rendering

The 300 TS is the upgraded Fujinon long-tele for 4×5 + 5×7 — the larger IC vs T 300 enables 4×5 architectural rise/fall not practical with the standard T. Multi-coating handles backlit subjects better than single-coated T 300.
