SUMMARY
Canon has filed patents for several new telephoto prime lenses for its RF full-frame camera system, focusing on compact designs. The patented lenses include a 130mm f/1.8, a 300mm f/2.8, a 500mm f/5.6, and an 85mm f/1.4. Notably, the 500mm f/5.6 design is significantly shorter than existing comparable lenses, suggesting it could be handheld. Canon is also optimizing optical weight distribution for better balance, shifting the center of gravity closer to the camera body. While these are patents and may not reach production, they indicate a potential for smaller, high-performance telephoto primes.
