TTArtisan launches the 250mm F5.6 Reflex

Judging by the bokeh, the lens is not particularly bright. T8? Or even T11?
I haven't done an exposure comparison yet, but T8 would make sense as the lens has a small diameter (67mm filter) and has a large image circle (no vignette correction in the above images) and an f/5.6 mirror has a large central obstruction. It is noticeably brighter than any of my 500mm f/8 mirrors, though. A full stop of variance between f and t is pretty typical of mirrors. Note that bokeh is somewhat limited by a 7ft MFD. Other than the foxglove shot, these photos are all fairly close to MFD.

Canon Patent Application: RF-S 12-30mm F4

I love crop as my go-to everyday carry cams. That said, I dont dont find these formulas interesting at all. Especially on crop, wider apertures are so valuable because your already dealing with limited dof. 1.4 on crop (thanks sigma) is just so great to have and use.

12-30..not wide enough (11 should be minimum) and doesn't go far enough. F4-6.3 version is completely DOA.

Also 20-40 on ff is good for some as well, just too weird for me if not a 2.8.

At least they are thinking about it. They could have done so much more with the M, and I still love my M gear. Even the build quality of the lenses was very solid, metal mounts, etc.

Canon Unveils the Future of Everyday VR Content Creation With New Dual Fisheye Lens

Nice, so now even the lower budget porn, can switch to VR productions.
The porn market pays promptly in cash. Also can make or break a product. One of the biggest reasons Betamax failed was that Sony wouldn't allow it to be used for porn. The VHS crowd had no such qualms.

Are Cameras delayed because of the EU?

Yeah that was Apple's excuse why they didn't want to join 2020 and use USB-C even though they had already adopted it for their tablets.

Standardization is a good thing. In a lot of these cases the EU does the world a solid. Getting all devices to the USB-C standard for charging is an easy win globally.
If standardization is so bloody good, why cannot the EU reg the outlets for their electrical plugs? Why have 5-6 designs when one will do? Heck, standardize their language. If there is anything costing the consumer money is having 24 different languages in the EU. Pick one for all commerce.

RF extenders with EF lenses

Looking at aliexpress for the third-party options available. Found one from JJC which almost seems like it was made with RF teleconverters in mind.
You'd still need to widen the opening, and more than with the Commlite. The reason people (me, included) use the Commlite adapter is that it has the widest opening to start. You can see that there's less protrusion on the bottom with the Commlite below than with the JJC above.

Opinion: AI Subscriptions are coming, and it shouldn’t surprise us

I am fully opposed to subscription requirements in hardware I have bought. Anything that the hardware can do, the hardware should be doing without the customer paying extra for it. Case in point would be Mercedes making rear axle steering (for reduced turning circle) a subscription service. So they installed the hardware but they will not let you use it unless you pay them monthly. Or BMW making heated seats a subscription service. This is a basic function of a car seat and in one of the most expensive brands you would expect not having to pay extra for it. Cloud services on the other hand, that I can accept, as long as it's not something that would have previously been included in the hardware (such as remotely locking/unlocking and checking alarm status, which I currently do using my fob).

As far as cameras, I suppose I don't see the need for my camera to be linked directly to the AI cloud. I could see it being connected to a computer for simply transferring images and I hope that will not be a subscription service because it seems to be rather basic these days. However, what happens after that is where I can see the use of AI. Pictures need to be sorted, enhanced, cropped and so on. I might do that manually but I can see AI being very useful in doing this and picking out the best when you have hundreds of pictures out of camera. All those things I would normally be doing myself in GIMP could be done by AI, just faster. better and at a lower cost. Photoshop could actually be made obsolete as far as working professionals are concerned.

Kodak is #1 in Japan

i know a couple of guys who love to play music of an analog vinyl record.
Thanks to heaven! I was able to replace lately my turntable - and keep on listening to my extensive collection that goes back to 78 rpms shellac records from my grandfather (and there are also the required styluses to play them). I understand less buying new music on vinyl, although I appreciate the physical product - cover, insets - which gives "personality" to each one, and gives work to photographers and graphic artists. I appreciate less the fight with dust.

For the same reason I would appreciate compact cameras easy to carry around, as long as they are better cameras than phones - less getting older cameras because their quirks becomes somewhat fashionable - for a while. But if people are happy, why took the toy away?

Cryptographic methods to authenticate photographs coming to the Canon EOS R1?

A simple certificate does not protect the content of the picture
If it doesn't, then blockchain doesn't do it either. With a strong (cryptographically secure) hashing algorithm, both do it exactly the same.

The only utility a public ledger seems to add to an in-camera signed hash of the image is recording the time when the image was registered in the public ledger (but not when the image was taken - that needs to be done in-camera, using a secure external time source).
