A Canon RF 24-70mm f/2.8L IS review by the folks at Photography Blog. They gave the lens a 4/5 stars rating and a “recommended”. The Canon RF 24-70mm f/2.8L IS as announced a in August 2019.
From the conclusion of the Canon RF 24-70mm f/2.8L IS review:
[…] it could […] be argued that Canon doesn’t yet have the camera bodies to match up to exactly how good this lens is. We’ve been using the RF 24-70mm F2.8L IS USM with the Canon EOS RP, which is an entry-level model, but even the higher end Canon EOS R perhaps doesn’t quite appeal to professionals.[…] the Canon RF 24-70mm F2.8L IS USM lens is an excellent performer – so if you do have the cash to spend on it you shouldn’t be disappointed. It’s capable of producing some very sharp images along with very pleasing bokeh. It’ll be interesting to see if Canon releases a very high resolution model to really take advantage of what the lens is capable of. Read the review at Photography Blog

About Canon EOS Ra
Canon’s first full-frame mirrorless camera dedicated to deep sky and night sky photography
Capture the intricacies of a starry night sky with the new EOS Ra camera — Canon’s first full-frame mirrorless camera dedicated to deep sky and night sky photography. Building on the success of the EOS R, the EOS Ra offers 30x magnification in both the viewfinder and in Live View shooting for more accurate focus.
Modified Filter for Enhanced Night Sky Recording
Positioned in front of the CMOS imaging sensor, The EOS Ra’s infrared-cutting filter is modified to permit approximately 4x as much transmission of hydrogen alpha rays at the 656nm wavelength, vs. standard EOS R cameras. This allows for a higher transmission of deep red infrared rays emitted by nebulae, without requiring any other specialized optics or accessories.
Original post:
Ahead of the its announcement, product images of the Canon EOS Ra leaked over at Nokishita. The product leaflet already leaked weeks ago.
The Canon EOS Ra is an EOS R full frame mirrorless camera modified for astrophotography. While the camera operation mode is the same as the EOS R, the EOS Ra has approximately four times the transmittance of hydrogen-alpha light (656 nm) as the EOS R.
Photographs of subjects that reflect a lot of infrared light will therefore appear redder than they actually are. This is good for astrophotography and less optimal for normal photography. With the EOS Ra it may not be possible to obtain an appropriate color balance and uneven colors may result when shooting normal subjects.
Alik Griffin did a huge job. He compared a large number of memory cards to see which one performs best on the Canon EOS 90D.
We recommend you have a look at Alik’s article to understand how he tested the memory cards, how he ranks them based on value and performance, and much more. To be honest, this might be one of the most complete articles on memory storage cards to be used on cameras.
As I wrote before, head over to Alik Griffin’s article to get the whole story, the test method, and more useful insights. It’s worth. There is also something to learn about counterfeit memory cards.
After the Canon patent application for a lens with built in vacuum cleaner, here is another interesting patent application filed by Canon.
Canon patent application 2019-185021 (Japan) discusses a high power flash unit with a built-in air cooling system. Air is sucked into the flash unit, passes through or around the flash head (the part that gets hottest) and is then put out. Effective cooling system.
An object of the present invention is to provide a lighting device capable of protecting a member related to light emission from heat associated with light emission. A light source, a first optical member that transmits light emitted from the light source, and a light source that transmits light emitted from the light source are disposed between the light source and the first optical member. The second optical member and the air sucked from the first space, which is the inner space including the light source, on the light source side of the second optical member, and the first optical member and the second optical member. An air blowing mechanism that sends the air to a second space that is a space between the optical members.
More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production are these:
