- Closest focus 9 m and the 67 mm thread are Japanese Wikipedia's figures; the Copal #0 shutter and f/45 as the minimum are from Steve Walton's lens list. No element count, weight or layout has been found, and no review discusses the 300mm on its own.
- Maximum aperture: f/8 in Japanese Wikipedia and in Walton's list of the four units; Walton's running text calls it f/11 at one point. Two sources against one passage, and f/8 is carried.
How to tell them apart
- 67 mm filter thread where every other GX617 unit takes 77 mm (Japanese Wikipedia)
- Focusing scale starting at 9 m, by far the longest closest focus in the system (Japanese Wikipedia)
T Fujinon 300mm f/8 lens unit (1993–):
- A complete module: lens, Copal #0 shutter and focusing helicoid on the GX617 bayonet, supplied with its own clip-on finder (Steve Walton; Japanese Wikipedia)
- T prefix on the ring; focusing scale to 9 m; 67 mm thread, the only GX617 unit not in 77 mm (Japanese Wikipedia)
- T Fujinon 300mm f/8 lens unit (1993–): The telephoto of the system, about a 74 mm lens in 35 mm terms (Walton). Its maximum aperture is f/8 in Japanese Wikipedia's table and in Walton's lens list; Walton's text gives f/11 once, which reads as a slip. No production figure or end date has been found.

History
The T 300mm f/8 is the telephoto unit of Fuji’s Panorama GX617, the interchangeable-lens 6×17 camera of December 1993, and the longest lens Fuji made for the format. Like the three shorter units it is a complete module of EBC-multicoated glass, Copal #0 shutter and focusing helicoid with its own clip-on finder, with speeds from 1 s to 1/500 plus B and flash sync at every speed. On the 17 cm frame it gives about the angle of a 74 mm lens on 35 mm film. It differs from its siblings in two numbers: the filter thread is 67 mm rather than 77 mm, and the focusing scale begins at 9 m, against 1.2 to 2.7 m for the others.
The aperture is the one point of doubt. Japanese Wikipedia’s table and Steve Walton’s list of the four units both give f/8; Walton’s text calls it f/11 once, and the figure is treated here as a slip in a review rather than a second version. Nothing else has been found: no construction, weight, price or production figure, and neither reviewer of the camera used the 300mm.
This history is AI-written, from the sources listed at the foot of the page. Where the record is silent it says so rather than filling the gap — but no human wrote these sentences.
