  • 2.36m-Dot OLED Electronic Viewfinder
  • 3.0″ 1.62m-Dot Vari-Angle Touchscreen
  • Dual Pixel CMOS AF II
  • 40 fps Electronic Shutter
  • Movie Digital IS
  • Vertical Movie Mode
  • Microphone Input, Headphone Output
  • Multi-Function Shoe, Wi-Fi & Bluetooth

The folks at DPReview posted their full Canon EOS R8 review. They gave it a Silver Award and a rating of 87%. Form their conclusion:

While the EOS R8 is hardly the highest-performing camera we’ve seen from Canon lately, it is an exemplary entry-grade option. It gives camera buyers most of the performance of the higher end EOS R6 II, but in a simplified package, rendering it straightforward enough for those trying a modern full-frame camera for the first time. The small shape and light weight make it easy to handle, and convenient to pack for a trip with its kit lens in tow.

[…] The biggest problem that the Canon EOS R8 runs into time and time again is its weak battery life. Although from a features and image quality perspective the R8 is highly competitive, the battery life is worst-in-class. On paper and in our experience, this is the camera’s Achilles heel, with anything intensive destroying battery life. With competing cameras like the Sony a7C or Nikon Z5 you’ll get up to double the number of images on a single charge. In an age where we have DSLR-like battery life from high-performance mirrorless cameras, the EOS R8 feels like the bad kind of throwback. If you pick up an EOS R8, spend the money for a spare battery – or a USB-C PD battery pack.

Canon Patent: RF 135mm f/1.8L IS USM Lens For The EOS R Camera System

Canon patent
View Post

And yet another Canon patent application for an RF-mount lens.

Canon patent application 2023099390 (Japan, published 7/13/2023) discusses optical formulas for what appears to be an RF 135mm f/1.8L IS USM lens.

From the patent literature:

Optical System and Imaging Device Having the Same

An object of the present invention is to provide an optical system equipped with an anti-vibration group that achieves both miniaturization and high anti-vibration performance, and an imaging apparatus having the optical system.
Telephoto lenses equipped with anti-vibration groups are required to achieve both miniaturization and high anti-vibration performance . In the telephoto lens equipped with the anti-vibration group of Patent Document 1, the anti-vibration performance is ensured by arranging the anti-vibration group at a position slightly away from the image plane position toward the object side, but it is difficult to reduce the size.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide an optical system equipped with a vibration reduction group that achieves both miniaturization and high vibration reduction performance, and an imaging apparatus having the optical system.

Example:

  • Focal length: 130.98
  • F-value: 1.85
  • Half angle of view: 9.38
  • Image height: 21.64
  • Total length: 147.99
  • Back focus: 17.45

Canon Patent: RF 100-300mm f/2.8L IS USM Lens

Canon patent
View Post

A new Canon patent application was spotted.

Canon patent application 2023099388 (Japan, published 7/13/2023) discusses optical formulas for what appears to be an RF 100-300mm f/2.8L IS USM lens for the EOS R camera system. From the patent literature:

Title of Invention

A zoom lens, an imaging device having the same, and an imaging system.

An object of the present invention is to provide a lightweight zoom lens that has high optical performance over the entire zoom range, and an imaging device and an imaging system having the zoom lens.

Description of the Related Art

In recent years, zoom lenses used in imaging apparatuses are required to have high optical performance over the entire zoom range and to be lightweight. In order to meet these requirements, the zoom lens has a first lens group with positive refractive power, a second lens group with negative refractive power, and a subsequent group including a plurality of lens groups, arranged in order from the object side to the image side. Lenses have been proposed (see Patent Documents 1 and 2).

A large-aperture telephoto zoom lens having a long focal length and a small F-number tends to have a large lens diameter, which tends to cause an increase in weight. In order to reduce the weight of the zoom lens, it is effective to increase the positive refractive power of the first lens group and reduce the lens diameters of the lens groups included in the subsequent group. However, if the refractive power of the first lens group is made too strong, it becomes difficult to correct spherical aberration, axial chromatic aberration, and lateral chromatic aberration, especially at the telephoto end.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a lightweight zoom lens that has high optical performance over the entire zoom range, and an imaging apparatus and imaging system having the zoom lens. Focusing is performed by moving the fifth lens unit L5 and the sixth lens unit L6 along different trajectories . Specifically, the fifth lens unit L5 and the sixth lens unit L6 move toward the image side when focusing from an infinite object to a close object.

Example 1

  • Focal length: 103.00-292.00
  • F-value: 2.90
  • Half angle of view: 11.86-4.24
  • Image height: 21.64
  • Total length: 333.61
  • Back focus: 31.93

Canon EOS R5 Mark II To Get 60MP?

canon rumors canon news eos r7 mark ii canon eos rv
View Post

A new rumor about the Canon EOS R5 Mark II from what appears to be a new, recently surfaced rumor outlet. We never heard from these guys and do not know who they are. That’s to say that you should apply the proverbial truckload of salt. Most rumors are nothing but speculations or educated guesses.

Latest has it that the Canon EOS R5 Mark II might feature a 60MP imaging sensor. The current model, the EOS R5, already sports a 45MP sensor. The bump to 60MP wouldn’t be that unrealistic. Quoting the source:

Through some industry people, we have found out that it is very likely that the EOS R5 Mark II will get a resolution bump to 60mp, which seems to be a resolution embraced by other brands already. Reports suggest that the camera is already in the hands of the usual early testers as Canon works to refine the camera.

The same sources said that the R52 will also have the capability of shooting 8K/60P. We do not know if the increased framerate for 8K/60P will be internal RAW. External recording capabilities are not yet known.

But, hey!, what about the all-destroying overheating? Not surprisingly, “Canon has developed better cooling for the successor [the EOS R5]”. Of course they did.

The announcement date is now rumored to be around the first half of 2024. All Canon EOS R5 Mark II rumors are listed here.

Forget rumors, enjoy life and snap pictures.
