Here is a Canon EOS R50 review. The EOS R50 is one of the more affordable cameras in the EOS R lineup, and comes with an APS-C imaging sensor.

At a glance:

  • 24.2MP APS-C CMOS Sensor
  • DIGIC X Image Processor
  • UHD 4K 30p Video Recording
  • Dual Pixel CMOS AF II with 651 Points
  • 2.36m-Dot Electronic Viewfinder
  • 3.0″ 1.62m-Dot Vari-Angle Touchscreen
  • 15 fps Electronic Shutter
  • Movie for Close-Up Demos Mode
  • Vertical Movie Mode

DPReview posted their full Canon EOS R50 review. They gave the EOS R50 a “Silver Award” and a scoring of 84/100. From their conclusion:

The Canon EOS R50 is a very capable mirrorless camera, especially when you take its $799 (with lens) price into account. It delivers in nearly all areas, most importantly photo quality and autofocus. Full-width 4K video with 10-bit HDR are big pluses, as well. The R50 is not without its flaws, however. Its controls are tight, the kit lens so-so, and 4K video suffers from noticeable rolling shutter.

While the R50 is easy to hold, with a surprisingly large grip, its rear controls are very tight, which led to many accidental button presses in our experience. The EVF is on the small side, but there’s just no room for a larger one.

One of the major issues with Canon’s APS-C RF-mount cameras at the moment is a lack of available lenses. As of September 2023, there were just three, and since Canon does not publish roadmaps, what comes next is unclear. In the meantime, you can use full-frame RF lenses, but they’re pricey, or adapt EF lenses, which can end up being bulky.

[…] in conclusion, the Canon EOS R50 offers a lot of bang for the buck, though the RF-S system has a way to go when it comes to lens selection. It’s one of the most portable mirrorless bodies out there

Canon Patent: 11mm F2, 13mm F2, 22mm F2, And 30mm F2 Lenses For RF-S Mount

Canon patent
View Post

Here is a new Canon patent application, for a bunch of fast primes for the RF-S mount.

Canon patent application P2023130885 (Japan, published 9/21/2023) discusses optical formulas for RF-S mount prime lenses:

  • 11mm F2
  • 13mm F2
  • 22mm F2
  • 30mm F2

From the patent literature:

An object of the present invention is to provide a rear focus optical system that is compact and capable of good aberration correction.

BACKGROUND ART

In imaging, it is required to suppress the generation of noise during zooming and focusing. In order to suppress noise during focusing, the rear focus (inner focus) method, in which focusing is performed by moving the lens group closest to the image side than the lens group closest to the object side, is recommended because it provides the best sound isolation effect from the object side lens. suitable.

Rear focus type optical systems are also required to be compact and have good aberration correction. In order to realize such an optical system, it is necessary to appropriately set the lens arrangement and the focal length of each lens.

The present invention provides a rear focus type optical system that is compact and capable of good aberration correction, and an imaging device equipped with the same.

Example 1

  • Focal length: 13.40
  • F value: 2.06
  • Half angle of view: 43.01
  • Image height: 12.50
  • Total length: 77.83
  • Back focus: 12.43

Example 2

  • Focal length: 11.30
  • F value: 2.06
  • Half angle of view: 47.89
  • Image height: 12.50
  • Total length: 77.85
  • Back focus: 12.44

Example 3

  • Focal length: 22.00
  • F value: 2.06
  • Half angle of view: 29.60
  • Image height: 12.50
  • Total length: 72.85
  • Back focus: 12.444

Example 4

  • Focal length: 30.52
  • F value: 2.06
  • Half angle of view: 22.27
  • Image height: 12.50
  • Total length: 75.88
  • Back focus: 14.49
