Our friends at Lensrentals.com have done what a lot of us wanted to see done, and that’s a teardown of the brand new Canon RF 70-200mm f/2.8L IS USM.

From Lensrentals.com:

There are some of you who are going to scream about how you want metal lenses. OK, Boomer, go get you a metal lens and show us how strong you are. On every other 70-200mm lenses we’ve disassembled, there are multiple metal parts that we can bend with our fingers. There’s not a damn thing we can bend with our fingers in this bad boy. This is going to hold up better than a metal lens, it’s probably sturdier, and it weighs far less.

I haven’t tested it optically. I haven’t even shot with it. But after looking inside it, I want it. The engineering in here is pure art. And even I, the person who mocks construction at any chance I get, can’t find anything to complain about. Check out the full teardown

It looks like Canon has made another gem of a lens construction-wise, but we’ll wait to see if they’ve also hit it out of the park optically.

Astronomik Clip-Filter for the mirrorless full format cameras EOS R and RP

The new clip filters can be used with all lenses on the camera body without any modifications.

The clip filters are optimized for use with normal camera lenses and telescopes.

All Astronomik filters are now also available as Clip filters EOS R!

The Astronomik CLS-CCD is our advice as an ideal “all-round filter”: The CLS-CCD largely suppresses artificial light pollution and enables deep, long-exposures even from locations with strong light pollution while giving your natural colors!

Beside the CLS-CCD the Astronomik emission-line filters H-alpha, SII and OIII with 12nm and 6nm FWHM are available.

The Astronomik ProPlanet 642 BP, 742 and 807 give the infrared photographer a wide range of filters at his disposal. The UV+IR blockers L-1, L-2 and L-3 complete the family.

Canon News has uncovered a patent for various super zoom optical formulas, and they’re all for the RF mount except for one that appears to be for EF-S.

As previously reported, Canon has released a firmware update for the Canon EOS R. It turns out it was released at the end of November but hasn’t yet been posted by Canon USA for whatever reason.

Firmware Version 1.6.0 incorporates the following enhancements and fixes:

1. Support for the RF 85mm f/1.2L USM DS lens has been added.
2. Corrects a phenomenon in which the function or setting value assigned to the control ring may change when the control ring is operated in Eco mode.
3. Corrects a phenomenon in which the camera may stop operating properly during “auto-transfer” when using Camera Connect with a Wi-Fi connection.
4. Corrects a phenomenon in which high-speed synchronization with use of an external flash may not operate properly depending on the camera’s setting for C.Fn2 “Set shutter speed range”.

We have received another set of specifications for the upcoming high-megapixel EOS R body, we dub it the “EOS Rs” for now. Canon may call it something else. The source claims to have shot with a prototype recently and that the plan is to announce the new camera in February 2020.

Canon EOS Rs Specifications:

• 75mp full-frame CMOS
• Sensor “focused on the dynamic range”
• Frames per second “… Sounded similar to the EOS R”
• DIGIC 9
• Dual Card Slots
• Joystick the same as the EOS-1D X Mark III
• Larger and higher resolution EVF than the EOS R
• Fully articulating LCD screen
• Fully weather-sealed
• Similar ergonomics as the EOS R (No touch bar)

We think more will be leaking about this camera in the coming weeks as we get closer to the planned February announcement.

A new Canon camera has appeared for certification and is likely some kind of new Rebel.

The only information about the camera from the certification agency is the camera will use the LP-E17 battery and is equipped with Wi-Fi (IEEE802.11b / g / n) and Bluetooth4.2.

We have been told a couple of times now that a “pro” EOS R mirrorless camera that is in the works will have some kind of a hybrid EF/RF lens mount. So this basically means that you’d be able to mount both types of lenses without the use of an adapter.

We were also told that this was being developed for the “EOS-1 style EOS R camera”, which would make a lot of sense. As I don’t believe the reduction of size for an “EOS-1” style mirrorless camera is all that important.

This is definitely a bit of a strange rumour, but if Canon could pull this off, it would be great for Canon shooters.

We’ll have some more information on this soon.

Canon obviously needs some “affordable” prime and zoom lenses for the RF mount, and a few JPO patent applications seem to suggest we’re getting closer to that being a reality.

Canon News has uncovered a complex and interesting optical formula patent from Canon, this one is for an RF 35mm f/1.4 Soft Focus lens design.

An RF 35mm f/1.2L has been rumoured for some time, but this is the first we’ve seen of this type of lens.

When Canon did their development announcement for the EOS-1D X Mark III last month, one of the rumoured features that wasn’t mentioned in the press release was the inclusion of in-body stabilization. Most have assumed if it wasn’t mentioned in the development press release, that the camera isn’t equipped with it.

A new source who claims to have shot with the EOS-1D X Mark III claims that Canon’s new flagship DSLR does indeed have in-body stabilization and that all future Canon ILC cameras will have the feature as well.

A lot was left out the development announcement about the camera, so I think there’s still a small chance that we see in-body stabilization in the EOS-1D X Mark III, but unfortunately, we cannot confirm this information to certainty.
