Overview

The Canon TV 800mm f/3.8 is a rare mirror lens originally for TV and SLR (R-mount) use, noted for its compact size relative to its fast aperture. As a mirror lens, it likely suffers from low contrast and donut-shaped bokeh, typical of the design. Build includes a guitar-handle grip. It suits collectors or enthusiasts of vintage Canon optics, but practical use is limited by its age, rarity, and potential issues like fungus. No optical test data is available from the excerpts.
