Canon Patent: 200mm f/2, 300mm f/2.8 And 500mm f/4 (RF mount?)

Canon Patent

Canon patent application for some telephoto zooms, for the EOS R system I guess.

Canon patent application 2020196094 (Japan) discusses optical formulas for three telephoto zoom lenses:

  • 200mm f/2
  • 300mm f/2.8
  • 500mm f/4

As a shooting optical system having a long focal length, a so-called telephoto type shooting optical system is known. The telephoto type photographic optical system is used, for example, in a single focus super-telephoto lens.

In the photographing optical system described in Patent Document 1, the second lens group having a negative refractive power is moved during focusing. Here, the second lens group is arranged at a position relatively close to the first lens group, and it cannot be said that the focus group can be sufficiently reduced in size and weight.

An object of the present invention is to provide an optical system that is lightweight and has chromatic aberration and other aberrations satisfactorily corrected, and an image pickup apparatus having the same.

IS A Canon RF 20-40mm f/4 STM Pancake Lens On Its Way?

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

Canon might soon announce a RF 20-40mm f/4 STM pancake lens for the EOS R system.

The rumor surfaced on Weibo, and not much is revealed. Here the machine translated text:

It is whispered that a Canon RF 20-40mm F4 STM full-frame mirrorless pancake lens that emphasizes portability and convenience when shooting movies is under development (generally credible). RF mount video pancake lenses have also been rumored once before, but there is no new news since then.

Guess it is entirely possible for Canon to release such a lens. Time will tell. Stay tuned.

Will The White Unicorn Be Announced With Two RF-S Lenses? (Canon EOS R7, again)

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

My my, the third Canon EOS R7 rumor in two days. If that does not mean something.

Latest about the white unicorn has it that Canon might announced two RF-S lenses (i.e. lenses for the RF mount and an APS-C imaging sensor) along with the fabled Canon EOS R7. Be aware that neither “RF-S” not “EOS R7” are anything official. These are just monikers invented by the rumoring community.

Says the source of the rumor:

At this time, we do not know what the lenses will be, but we have had a Canon RF 18-45mm f/4-5.6 IS STM on our roadmap for a long time, could this be an RF-S lens?

This is a rather irritating rumor: It has been spread for one reason only: there is certain probability Canon might indeed announce such a camera (i.e. an EOS R model with APS-C sensor). Sooner or later it will happen and someone will be able to tell they told us ¯\_(ツ)_/¯

All Canon EOS R7 rumors are listed here. Will this camera ever hit the shelves?

Here Are Some Alleged Canon EOS R7 Specifications (the white unicorn, again)

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

Yesterday we learned the Canon EOS R7 (with APS-C sensor) will get announced in Q4 2022. Today we have a set of alleged specifications. How handy!

Here are the rumored Canon EOS R7 specifications:

  • 32mp APS-C BSI Image Sensor
  • 20fps
  • DIGIC X
  • 1x CFExpress & 1x SD Card Slots
  • 4K @ 60fps
  • 1080p @ 240 fps
  • C-Log 3
  • The latest hot shoe
  • A combination of ergonomics from the EOS R6 and R5
  • Announcement in August 2022

If you follow us, you know we still do not entirely buy it. An EOS R model with APS-C sensor? Why would Canon make it?

All Canon EOS R7 rumors are listed here.

Stay tuned…

Canon RF 28-70mm f/2L Review (monster of a lens with monster performance)

Canon RF 28-70mm F/2L Review Rf Mount Canon Eos R

Here is a new Canon RF 28-70mm f/2L review. The RF 28-70mm f/2 is one of Canon’s “boutique lenses” for the EOS R system.

At a glance:

  • RF-Mount Lens/Full-Frame Format
  • Aperture Range: f/2 to f/22
  • Ultra-Low Dispersion Elements
  • Ring-Type Ultrasonic Motor AF System
  • Customizable Control Ring
  • Rounded 9-Blade Diaphragm

Optical Limits posted their fuzll Canon RF 28-70mm f/2L review, and they underline the many virtues of this not-budget lens, of this outstanding lens. From their conclusion:

The Canon RF 28-70mm f/2 USM L is everything that you can expect from it – it is a monster of a lens with a monster performance. This is especially true for the broader center quality which is as good as on the best prime lenses. The outer image field is also superb in the lower zoom range. The corners soften a bit at 70mm but remain easily on a good level. That’s on a 45-megapixel sensor. On 20 to 30 megapixels, the lens is almost perfect. The native image distortions can be noticeable at 28mm but not an issue beyond. The native vignetting is quite high at f/2 but that’s no different from prime lenses. Auto-correction comes to the rescue in both cases, of course. Lateral CAs are absolutely negligible. The quality of the bokeh is good but there is a little room for improvement here. However, that’s complaining on a very high level really. The rather massive focus-breathing isn’t ideal for videos though.

The build quality is excellent which isn’t surprising given its professional target audience. The materials and assembly quality are top of the class. Weather-sealing is a natural feature at this price point anyway […] Read the review at Optical Limits…
