Nice series. I especially like the 3rd picture.

Yes, you can build 90 nm RAM, but it is not power efficient in today's world and heat is one of the biggest enemies of the modern camera, so I still say zero probability that the memory is fabbed in-house. BTW, TSMCs CoWos challenges have little to do with the small geometries they are using to fab chips. CoWos is the multi-chip packaging process that allows AI GPUs to exist and the scale and connection density is pretty similar to a stacked sensor. Very precise dedicated machines are required and , no, just because Canon was successful with the R3 does not mean they automatically have enough capacity for an R5 or that a possible 45 MP stacked QPAF sensor is not more challenging to assemble. I am not saying that Sensor difficulties are the delay issue, but rather questioning the Magnesium theory. Magnesium is currently $2,700 per metric ton which translates to about 50 cents per camera when you take into account that the Magnesium will be alloyed with Aluminum, etc. before it is cast into a camera body. The price peaked in November and both the price and overall usage of Magnesium have been dropping recently, so shortage of supply is not likely that big an issue (if so, the price would be higher). The most likely reason for the delay is that current inventory levels are too high and that theory is reinforced by the rather continuous discounts we have seen for the last 6 months. The current level on inflation (at least in the US) has had a damping effect on discretionary capital purchases in general.a) that's just a fabrication issue. once you figure it out and can do so reliably it doesn't get any harder. Canon could do the ram chips btw - easily. Sony? not sure. also how much memory? given the area of a full frame sensor just because it's memory doesn't mean it's using small design rules past what sony or canon can achieve. it's not as if we didnt' have memory when 45 or even 90nm was cutting edge. 1Gbit SDRAM used anywhere from 100 to 60nm processes. and those chips were a lot smaller than the surface area of a sensor. 20 shot on sensor buffer of a 50Mp sensor would be 14Gbits. possible? it's not exactly out of the possibility.. So no, it's more than zero.
b) Canon bought a company to literally make that easier for them to do. it also depends on how they do the passthrough and the pads between substrates as well. edge placement is much easier than under each pixel as an example.
but do keep in mind that it costs a lot of money just to set up the sensor design. if you are making a million sensors, that's one thing, if you are making 10,000 - that does tend to be quite expensive. So while it may be easier for Canon to do right now, the design costs of the R3 sensor will still be pretty significant.
but once you figure out the manufacturing processes it doesn't get any more difficult with a new sensor, the processes and yields get better as time goes on. so the idea that the new sensors are holding up things? yeah no, i don't buy it.
the process and manufacturing of sub 5nm that TSMC is dealing with is entirely different than what we are discussing here. Sony uses 45nm from what I last recall seeing. Canon uses 90nm the last I've seen (a year ago).
The RF 16mm is a small and very cheap lens. It’s good for vlogging etc. but not very good for astrophotography due to issues with astigmatism, coma and heavy vignetting. I don’t know the Meike lenses. Samyang lenses are cheap also, and good for astro, although I believe it depends very much on the specific copy of the lens you get.What about third party lenses? Samyang, Meike etc? I have the RF 10mm F2.0 from Meike and it looks promising but not had a chance with the Milky Way yet. And what about the 16mm RF f2.8 prime - is that no good?
Thanks. I assumed if it was a Canon thing, then it would have been a rebate - they currently have one running, but only if you've bought a mirrorless body recently...It's a Canon Summer promotion. All the dealers are advertising it. By having it as a voucher rather than a "sale", they get around the laws governing sales prices.
They'll want us to buy both!
I never said there was no advantage. I said some people are going to choose another option. learn to read
Hope springs eternal, but I suspect it’s a reference to Action Priority AF."Quad Pixel" sensor design?
I went from the EOS50e to the 10D and never looked back. Those early digitals were game changers! Then it was 20D > 40D > 70D and finally R5. Wish I’d kept the 10D for pure nostalgia!May 17th, marked the 24th anniversary of the Canon D30, a camera that deserves not just a place in a museum, but a victory lap around the history of photography. Launched in 2000, the D30 wasn’t just another camera; it was THE camera. It brought professional-grade photography to the masses and brought high-quality digital capture

and dual slot, oh wait, that was the EOS M7.without a doubt the M6 Mark II is an insanely good camera.
I bet the designers wanted to do an M5 Mark II with IBIS and the RF group was worried it would kill the RF sales.
It's impressive how far behind not only the performance of their AF system is, but its interface and implementation. Canon has always excelled with creating user interfaces that are logically thought out and user friendly. Fuji almost seems hellbent on creating the opposite - it's arbitrarily complicated. Just the idea that they have automatic subject detection...only when the camera is entirely in full auto? haha WHY!?that reminds of when I tried out an A5 I think - I can't remember which number.
It made my original EOS-M's autofocus feel modern.
