Lensrentals tear down Canon RF 100-500mm

They mentioned that all their failures appear to come from around the same batch. Did they clarify what batch that was?
They haven't but of course it is not 100% certain that only one batch is involved. Even so knowing the serial numbers would bring us some peace of mind.

I think I will get it from Amazon.de sometime in the future. Right now it is not available for delivery so the next available item will most certainly come from a new batch.

Or I could try to get it locally from one dealer that right now does not have it in stock. I am in no hurry for this.

WW Compares 100-500mm to ef 100-400mm--So close?

I think I will keep my 100-400 II for now. It works nice on my R5 and I like to have a Canon teleconverter attached and still be able to retract the lens fully.
As a curiosity, the R5 autofocus also works ok with a Kenko 3x ef teleconverter. giving autofocus 1200mm at f17. The picture quality takes a big hit, but hey I have the option. The canon EF teleconverters are also stackable on the Kenko, the R5 actually managed to autofocus with a canon 2x and the Kenko 3x stacked. The autofocus was very slow but it managed to autofocus handheld at full zoom. And the image quality was rubbish. If my math is correct that gives autofocus on 2400mm at f33,6. This test, was just out of curiosity, I won't be using it.

Canon to announce the PowerShot Pick next week

Earlier this week I reported that Canon would be bringing their AI-powered concept PowerShot camera to market. This camera has appeared as multiple concepts since 2018.
DC Watch is reporting the new camera will be called the PowerShot Pick and preorders will begin via the Japanese crowdfunding site Makuake on January 29, 2021. This was the same way Canon first released the PowerShot Zoom, so I expect that the PowerShot Pick will become available globally shortly after.
The PowerShot Pick is powered by the marketing “AI”. The camera will be able to do things like analyze a person’s face and decide when the best time to take a photograph and will do it automatically...

Quad-Pixel AF and a global shutter coming in 2021?

I salivate over the idea of flash & fast shutter, but that would
"technically" give third party manual flashes an HSS function
for free. I hope the Canon-you-know-what-hammer doesn't
touch that.

No danger there. Except for the mentioned Hensel Expert D 250 Speed,
which is a rather hefty studio type mono flash, 99% of the third party
flashes can't dump their stored power within the necessary short time.

Only a few flashes will be able to make use of an extra two or three time
steps due to global shutter. There is room for new flash units as well
which can go all the way up. Flash duration is one of the hardest things
to reduce without giving up power.

This is the flash that I would put to use, I have five of them:

And this is the mobile power source that I have for it:

A 120V version is also available.

This gives me up to 16fps at 64 Ws with several thousand pops per charge.
Manual flash power, all manual mode, of course.

Yes, this narrows down the number of people with enough skills that
are needed to put this to good use. Or those who can fork over 4 grand
for the setup.

I don't think Canon needs to protect their own flashes for this.

Canon and Sony go at it in the latest BCN Japanese market share report

I've mentioned this before, but Canon has struggled with its cinema line. You got a hint from its quarterly reports starting from late 2019 or early 2020 when it put its cinema segment into industry and was quite silent about it after successive quarters. Multiple cinema news sites would later report that competitors like Blackmagic or Kinefinity were putting a dent into Canon's cinema market-share (At least in Asia).

Look at Canon's broadcast lens advertisement videos some time. They show the Canon lenses on Sony cameras. They are being realistic, broadcasters buy Sony cameras but use Canon or Fujinon lenses on them.

Canon may never be able to make up the ground, they are spending a big chunk of their war chest on acquiring industrial businesses in the imaging field. Businesses that are not adversely affected by the shift to smart phones for photography, or may benefit from it.

Which printer is right for you? The Canon PIXMA Pro-200 vs the Canon ImagePROGRAF Pro-300

Large prints also take up more storage space and are difficult to transport

I got also an A3 trimmer to cut the usual A4/A3 papers into more common photographic formats, and to cut boards to mount the prints too. An A2 trimmer starts to require a lot of space as well. If someone can dedicate enough space, maybe its own studio/workshop why not? Still many people have space constraints.

My prints are usually collected into boxes or books, and anything larger than A3 is uncomfortable. Prints to be hung on walls could justify larger prints, but I don't have my own gallery to exhibit them. Mounting large prints for display requires its own share of consumables and tools. Unless for someone it's enough to tape them somehow to a wall.

Some CF Express Card Tests

Yeah, Angelbird launched the card before the R5 came out, and then Canon's implementation of the standard essentially caused the issue. This sort of thing happens when you have a new "standard" that gets interpreted by the first few products that use it. Both companies (and at least one other card manufacturer I spoke to) were cooperative with each other, though, so it seems to all be working out.

7Artisans to announce an RF 10mm f/2.8 Fisheye soon

Does it matter? Software will be able to change the projection to anything else.

I'm curios.

Also, take that attitude to the extreme, and you can tell people to shoot everything with a fisheye, change projection to rectilinear with software, and crop. Voila, cheap replacement to the 800mm f/5.6.

It still won’t get you the coverage of the Nikon 7.5mm or it’s replacement the Nikon 8mm full frame circular fisheye.

An EF 8-15mm f/4L and adapter combo would get one there.

Or close to the ultimate fisheye so far for FF cameras, the Nikon 6.5mm with a 220º field of view, yep, it can see behind itself! It was originally developed for atmospheric observations.

There's a Nikon F to Canon RF adapter that would allow mounting the Nikon 6.5mm on RF cameras. I'm not sure how many photographers have the deep pockets to buy it, and a real usage scenario for it, e.g. VR.

Apparent crop marks on display screen that I can't get rid of - anyone know what these are?

It definitely varies depending on the lens. With my 70-200 2.8(ef) it is top to bottom but not quite all the way from side to side. With my sigma 150-600 5.6-6.3 it is less in both directions. I would assume you get 100% with a 1.2 lens or something like it.
I guess so. Before the forum was reset, jprusa hat a quote from Canon here that said only select RF and EF lenses had 100 % coverage.

I guess that means the OP's 24-105 4.0L is not one of those select ones either.

Venus Optics will launch an RF 12-24mm f/5.6 lens in 2021

The 14-24 f2.8 and 15-35 f2.8 are both unltra-wide zooms, you said there weren’t any new fast ultra-wide zooms, that is factually incorrect. That 14mm might not be wide enough for you wasn’t a comment I was replying to, you even mentioned the Sigma 14-24 f2.8!

Oh, I didn't bother repeating the "wider than 14mm", like the one this thread is about, yet again? Sorry...

Nikon cutting back production in Japan because of Covid-19

Good to see them communicating and expressing a sentiment of empathy and taken the issue seriously.

Though it comes as another entry in a lasting series of unfortunate events that weigh on the spirit.

I wonder whether all of it will amount to Canon not just delaying products but eventually compromise them to adjust to the new world.
The situation is just so sad and upsetting. In addition to the tragic debilitation of physical health and even death, peoples livelihoods have been destroyed and there are terrible problems of mental health. Some of us here who are retired or can work from home are lucky that we have an interesting hobby to keep us occupied and sane.

R6 view on laptop screen

Like joules says, maybe I am wrong. 100% Thunderbolt (which your computer has) supports HDMI into the laptop, but if that allows your laptop screen to effectively become a dumb screen I couldn’t say.

Thunderbolt 1-3 allow DisplayPort data on the bus, not HDMI. USB-C has an 'HDMI alt-mode', which allows HDMI data on the bus. If you have thunderbolt 3 ports, you can get both DP and HDMI alt-modes. As for supporting either of those into a Mac, that was only supported on iMacs and stopped being supported after apple moved to Thunderbolt2 on those machines (somewhere before 2015). Since my work laptop is faster than my personal iMac, I was a bit miffed to discover I couldn't use the iMac in screen mode, which my old one did support.

Back to the OPs question: I'm using a 'Camlink 4k' from Elgata/Corsair, which works quite well for capturing the HDMI output of the camera. Since it shows up as a proper video input, it "just works". You could alsp use the Canon Webcam thing or EOS Utility if you don't need it to be a proper video input.

Let’s talk about the Canon EOS R1 development [CR2]

My primary concerns are IQ, DR, Focus and color.
Could care less about Video.
Convince me an EVF can equal an OVF for pro and Olympic Sports.
Fuji and Hasselblad have superior color Canon needs to step it up.
It has to be at least 45MP's.
Dual same media.
Have bags of batteries and cards, Think of those who own 1DX 1DXII and 1DXIII.
If current kits are EF glass consisting of 35 50 24-70 70-200 300 400 200-400 and 3 Bodies. If Canon can't meet the specs we asked for, then we are not replacing the above mentioned kits.

Happy to spend budget that makes our agency better positioned.
