A new rumor, about the Canon RF 300mm f/2.8L IS lens. Is it coming? The…
A few days ago we got a rumor suggesting Canon might be set to release a RF 5.2mm f/2.8 lens. Today we know a bit more.
As Nokishita added to their original rumor, the RF 5.2mm f/2.8 lens might indeed be a dual fisheye lens for VR (virtual reality) applications:
The product category of canon’s RF 5.2mm f/2.8 L Dual Fisheye seems to be a VR lens.
There is more. Months ago a Canon patent application was spotted that seems to be related to the rumored RF 5.2mm lens. The patent application P2021-51282A (Japan) discusses optical formulas for a stereo lens for a full frame mirrorless camera. From the patent literature:
PROBLEM TO BE SOLVED: To provide a small lens device that can obtain a natural stereoscopic effect by setting an appropriate length of a base line.
SOLUTION: A lens device (200) includes: a first optical system (201R); a second optical system (201L) arranged in parallel to the first optical system; and a lens mount unit (202) attachable to a camera body, the first and second optical systems each having a first optical axis (OA1), a second optical axis (OA2), and a third optical axis (OA3) in order from an object side to an image side. A distance (L1) between the first and second optical systems is larger than a dimeter (φD) of the lens mount unit, and a distance (L2) between the third axes of the first and second optical systems is smaller than the dimeter (φD) of the lens mount unit.
A RF 5.2mm f/2.8 lens for the EOS R full frame mirrorless system. Interesting times ahead.
