long time ago, when the RF system just came out, I was critisized fro saying that the M series will be eventually abandoned for a crop RF camera and mostly lenses. But time shows that it is the logic in keeping one line of lenses is the crrect path for any camera brand. For lenses aer used for much longer period of time than camaras. For example I use the same EF lenses that I bought for my 7D even that I changes to RF camera.Okay, it's been over 3 years since the RF-S lineup was released by Canon, and they have yet to really capitalize on what those cameras were. I know some people dismiss the EOS-M system and what it was for Canon and wanted it to die (Ahem, Craig), but for me, anyway, it was the perfect […]

Even in EF days, APS-C was threated like that. Lens selection was always limited to cheap dark zooms and kit lenses with very few exceptions, like the 17-55.To me, it almost seems like Canon is getting ready to ditch their APS-C lineup, which so far has been treated like a stepchild.
Thanks! I'm glad you're enjoying the photos. The Hummingbirds are probably my favorite avian family (and among the most difficult to photograph well).I love your exotic hummingbirds. I have a bunch of hummers who live in the back yard, but mostly Anna's with a few Rufus in the summer. You have found some very unusual species.
The male Crowned Woodnymph often appears to be all dark, but when the light hits it just right the brilliant emerald and violet plumage is stunning. I photographed this individual while birding at La Florida, Bosque de Las Aves, at km 18, Colombia, November, 2025.
R5MkII RF200-800mm

The comparison for the R5 with R5Mk II prices is for inflation in the 2020-2024 period. The BLS number you state is for 2024-2025, so, like the rest of your “arguments” it is completely irrelevant.You are making my point for me.
For inflation they take a basket of goods (Food, Housing, Transportation, medical, electronics, etc.) and assign a weight to each item based on how much the average person purcfhase that item as a precentage of theri budget and then looks at the prices difference of all of those items along with the weight to generate a top line number.
So the prices of individual goods going up is what causes inflation not the other way around. It's like me saying Housing is costing more and you say well actual no housing is just going up because inflation. No Housing IS going up and that IS what is being recorded as inflation.
Here is the recent BLS report breaking down all the compenents of inflation:
https://www.bls.gov/news.release/pdf/cpi.pdf
On page 13 you see the price increase of photographic equipment which is 5.7% year over year from Sep 2024 to Sep 2025. So the BLS is saying the retail price of photographic equipment is up 5.7% The weighted average of photographic equpment was .020 as this is not a category people spend a decent percentage of their income on.
When you factor ALL the items to their approriate wight factor the BLS calcuated top line inflation at 3% Not only are camera prices increasing, they are increasing faster than the weighted average of what most people buy.
Meanwhile smartphones decreased almost 15%.
For liquid cooling, you wouldn't immerse the sensor in liquid, but rather attach a thin liquid chamber to the back side (i.e. the non-illuminated side) with very small and light tubes to carry the liquid to a heat sink (either the body of the camera of a small radiator). A micro pump would be required, but would only be needed when the sensor was getting too hot. Mechanically complicated, but it could actually be quite small and light. Water has the highest specific heat of handy liquids (ammonia is higher, but it is nasty and needs pressurization), so the most likely choice. The Canon patent is clearly aimed at mechanical simplicity, which makes sense, but liquid cooling is possible. High specific heat is important for maximum heat transfer with minimum mass of fluid.
Where are the equivalents?....
Seems there are 2 likely answers.
1) They did not sell well enough to make RF-S equivalents.
2) They will make them, but are not high priority.
The fact that Canon Forum users cry out for them, does not in any way indicate that they would sell well. To repeat for the nth time on the forum, we are not the target market.
The simplest (thus generally smallest, lightest, and/or cheapest) pancake designs are those with focal lengths near or slightly longer than the flange distance. It’s not an absolute requirement but it minimizes compromises. The EF 40/2.8 is close to the 42mm EF flange distance.
From a design perspective, the RF 28/2.8 is the pancake successor to the EF 40/2.8, given the 20mm RF flange distance. The RF 28/2.8 is only 2mm longer than the EF 40/2.8.
you have it already. the RF28mm f/2.8 STM is it.Speaking of pancake lenses, I have never understood why Canon haven't released a RF version of the EF40/2.8. A third of the weight and length of the RF42/1.2 and adapting the EF version cost so much more and doubled the length and weight.
I can't imagine the pricetag on a 400-600 f/2.8-4.0 being less than $15-20k, so about twice as much as I'm willing to put down lolI've not tried the new 70-200/2.8 Z, but I am very familiar with the older EF 70-200/2.8 II counterpart. It was an astonishingly sharp lens even with a 1.4x tc. It af our resolves any of the current Canon sensors. The 2x less so, still sharp but want's great with close objects and generally needed stopping down 2/3 stop to remove the slight haze around highlights. The thing is, a pair of teleconverters is a lot lighter than lugging around another sized lens. Even the 2x TC works well if that's the only thing you have on you. I appreciate that this new RF Z version is a tad sharper again, but it's still in the same ball park with teleconverters.
The RF 70-200/2.8 is a miracle in packaging and light weight construction by comparison, but we all know of the lack of TC support for this sweet lens.
The RF 100-300mm f2.8 is a very different beast. With tele converters, it's pushing into wildlife and birding reaches. Even with a 2x TC (making a 600mm f5.6) it just about keeps up with the R5's resolution of it's mighty sensor. It's a very viable and versatile lens range (100-300/f2.8 > 140-420/f4>200-600/f5.6) and it only cost you the size and weight of a pair of teleconverters. It's never going to compete directly with a 70-200mm f2.8 even though it's got a fair amount of overlap in the focal range and aperture. The Rf 100-300/2.8 is kind of a bridge lens between the 70-200/2.8 and the longer wild life lenses.
I have a few friends who regaulrly use a EF300mm f2.8 II LIS with a pair of teleconverters as their long lens of choice. It's a back friendly size and weight with a nice price point with an excellent reach / brightness. One of them is considering swapping over to the RF 100-300/2.8 so they can ditch the need fro their EF 70-200/2.8 lens and just use the one lens. If Canon made a RF 400-600 f2.8 - F4 zoom lens that's a simular weight to my EF 400mm f2.8 II L and it's as sharp, then my ears might prick up and colour me curious.


Mercedes has higher prices across the board for comparable models than Lexus (which are made by Toyota Motor Corporation), and Mercedes does not offer low end models like Toyota. By the (dubious) logic of your assumptions, professional drivers must be driving most of the Mercedes cars on the road.In 2024 Canon was at about ¥580B and Sony was at ¥670B. I'm pretty sure I saw a break down of lens sales and Canon sells more first part lenses than Sony. So if Canon makes more money from lenses and we subtracted the sales of lenses then the revenue left over for camera body sales would be even wider. Canon sells a lot more camera bodies than Sony. The result is that the only way Sony is ahead in revenue is because even though they sell less cameras and less lenses is that the camera bodies they are selling are more expensive. They need to be 1.75x to 2.0x more on average.
My wild baseless assumption is that becuase Sony is selling LESS camera bodies that are on average almost double that they have a smaller amount of hobbyist buying these more expensive bodies. This assumption is validated with the Sony prices being accross the board higher for comparable models and the lack of models available on the lower end.
I‘ll summarize your “answer” for you: You have no data to backup your claims.

USA CPI is not relevant. OEM marketing departments set the recommended selling price.For inflation they take a basket of goods (Food, Housing, Transportation, medical, electronics, etc.) and assign a weight to each item based on how much the average person purcfhase that item as a precentage of theri budget and then looks at the prices difference of all of those items along with the weight to generate a top line number.

I'm guessing from analyzing past sales and current trends they determine which products to prioritize in development and production.I would like to see wide aperture RF-S zooms and primes from Canon.
I don’t get why they do think they wouldn‘t make enough money with them and so don’t offer them.
In the meantime I enjoy using the great Sigma 18-50/2.8 with my R50 together with the great (for APS-C) RF100-400.
Light, lovely travel combo.![]()
I agree.
That is also likely why OP labeled their statement a rant.
For what it is worth, I also agree with the oft repeated statements of Canon's business decisions.
I'm sure we all have desires for some type of gear that Canon has not produced. Just looking at the numerous posts of future camera features can be considered as rant premonitions once some do not come into fruition.
And several will be posted and read here. The forum universe is partially powered by this energy.
Have you ever heard of inflation?
The R5 was launched in August 2020 for 3900$. The R5 Mk II was launched in August 2024 for 4300$. When you adjust 3900$ for US inflation from 2020 to 2024, that 3900$ price would be 4740$, i.e. 21% price increase.
You can check the numbers for yourself:
- US BLS: https://www.bls.gov/charts/consumer-price-index/consumer-price-index-by-category-line-chart.htm
- Inflation calculator from FED of Minneapolis: https://www.minneapolisfed.org/about-us/monetary-policy/inflation-calculator
I think the implication is, while the average image quality (probably especially sharpness) of lenses is much better now, the RF 45 is has a number of flaws that were more common in the past (but I don't know how true that is).Do you meant to say that the RF 45mm doesn't need software to correct its image? Otherwise I'm perplexed about what's special about lenses from the 1990s-2000s.
