Canon Patent: Shift-compatible Mount Adapter Supporting Electronic Contacts

Canon Patent

Here is a new Canon patent application: shift-compatible mount adapter with support for electronic contacts.

Canon patent application P2022052536 (Japan) discusses the technology to implement a shift-compatible mount adapter with electronic contacts. This seems to be a rather interesting thing. Not the first adapter Canon makes. Assuming this adapter is for the EOS R lineup, it has ti be said that so far there are no tilt-shift lenses for the system.

PROBLEM TO BE SOLVED: To provide a mount adapter capable of easily shifting an interchangeable lens with respect to an imaging surface for shooting.

However, the prior art disclosed in Patent Document 1 is a configuration for preventing mechanical interference between the camera body and the interchangeable lens, and has a predetermined optical axis with respect to the image pickup surface like a TS lens. It is not possible to shift the image by a variable amount and shoot. Further, if the TS lens configuration is mounted on the mount adapter, the number of parts increases and becomes complicated, which leads to an increase in cost.

FIG. 2 is a cross-sectional view illustrating the adapter 100 in this embodiment. As described above, the adapter 100 is an adapter that is arranged between the camera body 10 and the interchangeable lens 20 and can be attached (connected) to the interchangeable lens 20 and the camera body 10. The adapter 100 is also a camera accessory that electrically connects the camera body 10 and the interchangeable lens 20. A CPU may be provided in the adapter 100 to perform signal conversion and the like.

The Canon patent was spotted by Asobinet. More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production are these:

Canon Might Announce 2 Tilt-shift Lenses (with AF) Along With A High Res EOS R Model

Canon Eos R7 Eos R10 Eos C5 Eos R1 Eos R5c Canon Rf 16mm Rf 35mm F/1.2L EF Lenses Tilt-shift Lenses Rumor

New rumor has it that Canon is set to announce two tilt-shift lenses with auto-focus for the RF mount and a high resolution EOS R model.

Canon Rumors reports that Canon will announce two tilt-shift lenses for the RF mount. These would be the first tilt-shift lenses with autofocus: Canon TS-R 14mm f/4L and Canon TS-R 24mm f/3.5L. No other specifications about these lenses nor do we have a clear announcement schedule. However, we think it is safe to assume Canon will indeed release these lenses, maybe towards the end of 2021 or beginning of 2022.

As for the high resolution EOS R we already know that it is coming. Indeed, such a camera is rumored since a while. Latest rumor suggests a sensor resolution of more than 100MP, previous rumors suggested a resolution between 80MP and 90MP. It’s not clear if we can expect the high resolution EOS R in 2021.

Stay tuned.

Canon TS-E 135mm f/4L MACRO review (superb creative tool, ePhotozine)

Canon TS-E 135mm F/4L MACRO

Canon TS-E 135mm f/4L MACRO at a glance:

  • EF-Mount Lens/Full-Frame Format
  • Aperture Range: f/4 to f/45
  • Two Ultra-Low Dispersion Elements
  • Subwavelength Coating
  • Maximum Tilt: +/- 10°
  • Maximum Shift: +/- 12mm
  • Minimum Focusing Distance: 1.6′
  • Maximum Magnification: 0.5x

ePhotozine reviewed the new Canon TS-E 135mm f/4L MACRO, a specialised, tilt-shift lens. This is a Canon L lens, everything is top notch. Unfortunately, the price is too, $2,199.

ePhotozine’s conclusion:

The Canon range of tilt and shift lenses is unique and impressive, and without a doubt, if there is a commercial need for what they offer then they will be purchased for that purpose and the price will be acceptable. The fact that it is a macro lens as well as a tilt and shift lens is a very powerful combination.

The Canon TS-E 135mm f/4L Macro is a beautiful lens and has the potential to produce beautiful and unique results, but for an amateur purchase, we would need deep pockets. However, for some, it might be a possibility and it would be a very desirable lens to own. Read the review…

ePhotozine gives the TS-E 135mm f/4L Macro a rating of 4.5/5 (highly recommended).
