Sadly no, as a result of the RF 500mm f4 on this patent is 2,8 cm longer than the present EF 500mm f4. The DO lenses are lighter and far shorter.
Agree that it will not be DO. Nevertheless, the size of this lens patent (if it turns into an actual lens) will probably be nearer to the EF model than you counsel. The EF 500mm f/4L IS II is 383mm, that is the spec of the particular lens. The 411mm size above is the size of the optical components, which is true for all lens patents. To estimate the size of the true lens primarily based on a patent, you’ll want to subtract the flange focal distance, which is 20mm for RF. Thus, the RF lens described right here could be ~391mm lengthy, solely 8mm longer than the EF model.
