Canon Patent
View Post

Here is the first of a batch of new Canon patent applications.

Canon patent application 2024099414 (Japan, published 7/25/2024) discusses methods and optical formulas for two PowerZoom lenses:

  • 12-30mm F4-6.3
  • 24-50mm F4-6.3

From the patent literature:

  • A zoom lens is provided that has a wide angle of view, is compact, and has high optical performance while allowing rapid zooming.
  • [Background Art]In recent years, there has been a demand for zoom lenses that are wide-angle, compact, and high-performance (high resolution). In addition, in recent years, the demand for moving images has increased, and in order to achieve smooth zooming, zoom lenses with electric zoom functions are required. As a wide-angle optical system, a negative lead type optical system is known. Patent Document 1 and Patent Document 2 disclose a negative lead type zoom lens in which the first lens group is immobile relative to the image plane during zooming.
  • SUMMARY OF THE PRESENT EMBODIMENTS
    An object of the present invention is to provide a zoom lens which has a wide angle of view, is compact, has high optical performance, and is capable of rapid zooming.

Example 1

  • Focal length: 14.40-29.10
  • F-number: 4.10-6.26
  • Half angle of view: 43.6-25.3
  • Image height: 11.51-12.90
  • Overall length: 78.75
  • Back Focus: 11.50

Example 2

  • Focal length: 24.70-48.50
  • F-number: 4.10-6.14
  • Half angle of view: 41.5-24.0
  • Image height: 18.19-20.62
  • Overall length: 107.48
  • Back Focus: 20.26

Example 3

  • Focal length: 12.36-27.16
  • F-number: 4.10-6.40
  • Half angle of view: 47.9-26.2
  • Image height: 10.67-12.59
  • Overall length: 79.81
  • Back Focus: 11.50

Canon RF 24-50mm F4.5-6.3 IS Review (frustrating areas of regression, D. Abbott)

RF 24-50mm
View Post

Here is a professional review of the Canon RF 24-50mm F4.5-6.3 IS lens. This is one of the less expensive lenses for the EOS R system (i.e. a kit lens)

The lens at a glance:

  • Full-Frame Lens
  • STM Stepping AF Motor
  • Optical Image Stabilizer
  • Focus Control Ring
  • Two Aspherical Elements
  • Super Spectra Coating
  • 7-Blade Diaphragm
  • Compact and Lightweight Design

Dustin Abbott reviewed the Canon RF 24-50mm F4.5-6.3 IS. Here are his findings. It’s a very exhaustive and complete review, and I suggest you have a look at it (especially if you are pondering to get the RF 24-50mm). From Mr. Abbott’s conclusion:

[the RF 24-50mm] serves a specific purpose, namely to provide a small, lightweight, inexpensive lens for people to add to their Canon EOS R8 (and future cameras) so that they have a lens to actually take pictures with. I remember my first Canon DSLR purchase (the Rebel T1i) and it came with an EF-S 18-55mm IS lens. I didn’t love the lens (sold it fairly quickly), but it gave me something to use in the first couple of months so that I could use my new camera. There are places where Canon has improved things (autofocus is definitely better), but there are also some really frustrating areas of regression. Canon’s maximum aperture range on these type lenses has become decidedly worse, as Canon clearly banks on the improved ISO performance in modern cameras covering for the slower maximum apertures. They’ve also become increasingly reliant on software to cover for the hardware shortcomings, with massive amounts of optical correction needed to make the image usable.

The review is not very positive. On the other hand, this is a kit lens, and at $299 I guess you can not expect much more. Mr. Abbott’s review comes with test charts, sample photos, ISO test, there is nothing that is missed. And if you’re not into reading reviews, you can watch the video-review below.

It appears DPReview is still alive and kicking, despite some recent news. Just a matter of time, I guess.

At a glance:

  • Full-Frame Lens
  • STM Stepping AF Motor
  • Optical Image Stabilizer
  • Focus Control Ring
  • Two Aspherical Elements
  • Super Spectra Coating
  • 7-Blade Diaphragm
  • Compact and Lightweight Design

DPReview posted a set of Canon RF 24-50mm f/4.5-6.3 IS sample pictures, all taken with a Canon EOS R7 and EOS R8. The images can be downloaded for your pixel peeping pleasure. The RF 24-50mm f/4.5-6.3 IS seems to be a rather interesting little lens.

Is This The Upcoming Canon RF 24-50mm F4.5-6.3 IS STM Lens?

An image surfaced on Instagram, allegedly it shows the upcoming Canon RF 24-50mm F4.5-6.3 IS STM (image on top). But is it real?

For the time being we have no indications the image might be a fake (nor to we have indications it might not be a fake). In any case: take it with a grain of salt. Regarding the watermark, it seems to be sort of joke to a well known rumor site.

What do you think, image real or fake?

Announcement of new Canon gear on February 8, 2023. Stay tuned…
