Canon Patent: 24-100mm f/2.8 And 24-70mm f/2-3.5

Canon Patent

Here is a new Canon patent application, for a 24-100mm f/2.8 and a 24-70mm f/2-3.5 lens. The design seems to be agnostic, meaning no mount type is specified.

Canon EOS R3 Review (not a camera for everyone, D. Abbott)

Canon Eos R3 Review Canon Cameras Eos R1

Here it is: the Canon EOS R3 review I was waiting for.

Canon EOS R3 at a glance:

  • 24MP Full-Frame Stacked BSI CMOS Sensor
  • Dual Pixel CMOS AF II, Eye Control AF
  • 6K60 Raw and 4K120 10-Bit Internal Video
  • 30 fps E. Shutter, 12 fps Mech. Shutter
  • 5.76m-Dot EVF with 120 fps Refresh Rate

  • Wired LAN and 5 GHz Wi-Fi Support

Dustin Abbott posted his Canon EOS R3 review along with his exhaustive findings. What I like in his reviews is that they are a balanced mix between lab testing and real world experience. Few reviewers get this mix right. From his conclusion:

[…] the EOS R3 is a crucial camera if Canon wants to get working professionals out of their DSLRs and into mirrorless…and all of those nice, shiny, expensive RF mount lenses.  The EOS R3 brings some genuine innovation to the 1D series design, including the Eye Control AF, in body image stabilization, and a faster burst rate than any 1D body has ever seen.  30FPS means that you have plenty of opportunities to choose the perfect frame.

If you put the EOS R3 and the Sony Alpha 1 together, the Sony looks like (by far) the cheaper camera even though it costs about $500 more. It is basically the same size as all of Sony’s other full frame mirrorless models, while the EOS R3 looks like the high end sports camera that it is.

[…] At the end of the day, however, this is not a camera for everyone. It’s too big, too heavy, and too expensive. It’s strengths are overkill for many photographers, and I doubt it will ever sell at the levels of cameras like the EOS R5 or R6.

As usual the review comes with a huge set of sample pictures, comparison charts, and all the information you might want to know. Dustin’s reviews are what I look for when I am about to purchase new gear. As usual Dustin Abbott also releases a complete video review. See below.

Canon EOS R5c To Be Released Q1 2022?

A new rumor about the Canon EOS R5c. A camera some wish would come to existence. Time will tell.

Be aware that the moniker “EOS R5c” is nothing official, it was invented by the rumor and fun community. The EOS R5c is said to sport a 45MP sensor (same as EOS R5). Here is the list of rumored specifications:

Canon EOS R5C Information

  • 45mp full-frame sensor
  • DIGIC X
  • Canon Log 3
  • Canon Log 2 is still being discussed
  • Unlimited 8K30P recording in Cinema RAW Light. XF-AVC and MP4
  • Timecode in/out
  • The same multipurpose hot shoe as the EOS R3. Which will work with accessories such as the Tascam XLR module.
  • Active cooling
  • 3/8″ or 1/4″ mounting point on the EVF for a top handle that won’t interfere with the hot shoe.
  • Full-size HDMI Port
  • The LCD has been moved further back to accommodate the cooling fan. So this likely means that it won’t recess into the body like the Canon EOS R5.

Previous rumors pointed at January 2022 for the announcement. Now it is Q1 of 2022. No information about the price. We recommend you take this rumor with a grain of salt.

Stay tuned.
