New rumor has it that Canon is set to announce two tilt-shift lenses with auto-focus…
Rumor has it that the first super telephoto lens for the Canon EOS R system could be the RF 500mm f/4L IS.
No announcement date or specifications so far. However, there is a Canon patent application (US 20190155003) with describes the optical formulas for various super telephoto lenses for the EOS R system, among them a 500mm f/4L:
- Focal length: 490.00
- F value: 4.12
- Angle of view: 2.53
- Image height: 21.64
- Lens length 412.08
- Backfocus: 33.39
The rumor might have some validity. When Canon will announce a mirrorless alternative to the Canon EOS-1D X series, then they likely will/could also announce this telephoto lens. But it’s a long way to go in opinion. The next Canon EOS R camera will most likely be a high resolution model.
