That logically tells us they were considering to NOT make another one.

With Powershots, the G7X and SX only went back into production because market demand was so strong.
You are free to infer whatever you want from the information available.
I am free to consider other possibilities.

Just saying that Canon (and all the other manufacturers) will tell us whatever is they think will keep us buying their gear.
I believe they (like all others) have been less than forthcoming with the truth is a few occasions. They are corporations beholden to their stakeholders, not to us.
You are indeed free to think differently from me.

And bees have no sex-linked chromosomes at all. Yet we teach kids about ‘the birds and the bees’. Lol.

Can the mods change the tread title as at present doesn't seem to have anything to do with RF 300-600mm

@Celts88, meet the Internet. The Internet, meet @Celts88. It’s clear that you two are previously unacquainted.

The RF 14/1.4L has two VCM motors, though I think that's the only lens so far with that configuration.

It seems that the RF 85/1.4L VCM is also VCM-only, without a Nano USM motor. Several online reviews state that it has both, but I can’t find anything from Canon saying anything other than VCM. The lens appears to have only a single focusing group, whereas lenses with VCM + Nano USM or Dual Nano USM have two focusing groups (one floating).

Eric84 said:
Maybe a dumb question, but would it be impossible for Canon to take the RF 50mm F1.2L (or the 85mm) USM and "just" replace the USM-motor with a VCM style motor? or is the motor inside a lens so composed that a total redesign of everything is necessary?

I suspect a redesign would be needed, for either a smaller focusing group or two focusing groups. I believe Ring USM is still more powerful. Compare the focusing group of the RF 85/1.4L VCM (3 elements) with that of the RF 85/1.2L (7 elements), for example.

Lol, yeah Canon has a team of PR flaks working around the clock to deflect, defer and diffuse the massive public outcry over this huge issue. The burning resentment raging through the camera market is killing Canon’s camera sales, leaving them in the embarrassing position of being #1 in ILC sales for the 23rd year in a row.

If Canon doesn’t stem this massive tide of customer angst, what will happen to their market leadership?

Nothing, of course. The minuscule number of people who gripe about this non-issue on the internet might switch brands. But probably most of them will just keep whining and do nothing.

USM is a vibrating drive that rotates a glass group, whereas VCM pushes/pulls using the magnetic force. The glass groups can probably be recycled, but moving from USM to VCM specifically probably requires some case redesign. Still, Yongnuo was able to clone the EF 14mm using a gear drive motor and still maintain the same form factor so probably not too big of a deal.

I’d love to see winning EF designs recycled into quality but relatively affordable consumer lines that keep prices down by avoiding the glass R&D costs to keep OEM lenses with Canon benefits like DLO more affordable for younger shooters. I doubt that will happen any time soon, but over the expected life of the RF line probably not crazy.

Canon has recently thrown everything into the 14/1.4 to the extent that it is an expensive but wonderful lens. I fear that they may do the same with the TS-E lenses.

Laowe have 2 lenses for tilt/shift or shift only to differentiate from a 25% price difference. This makes sense to me as I would only use shift if I was to get one and AF wouldn't be a critical issue. To line up the vertical elements would be manual/tripod. Not sure how AF could also shift automatically for composition.

I can't imagine Canon having 4 options for one focal length: shift/tilt-shift, AF or manual so Canon is likely to add everything in and then be a marvellous technological creation but with a $$$$$ price ("The Homer"?).... especially for a 14mm TS-R
Not even sure what the nomenclature would be for a shift only lens "S-R"?

I have the Laowa 35mm TS for my X2D II. It is a good lens in terms of IQ, but it is also quite a bit heavier than the 2 TS-E lenses I used to have (24mm II and 17mm)... so much so that I cannot use it without tripod, while I was comfortable to hand hold the TS-E lenses. Tilt is actually doable hand held, but shift, especially vertical, is a problem. for me at least

It sounds better in press and interviews when journalists ask about it. So instead of saying "we not allow it", they can just say they negotiating or something.

Sure it does. Canon can say they're not technically lying so no suing them (as if one would).
But the bottom line does not change: however they do it, they are still preventing 3rd part FF AF lenses for RF.
It's their mount so they are absolutely free to do as they please with it. As I, as insignificant as I am, am free to be sour about it.

That is a reasonable conclusion, but another one is that Canon set the price too high just to make enough money for themselves to sense when we buy a third-party lens instead of a Canon lens.
A price that makes sense for Canon does not necessarily make sense for a third party.
They all are businesses.

Both can be true.

Long story short: I was planing to go today on the other side of the Island but landed in Waikiki: decided to give one more chance to the Orange-Cheeked Waxbil (last seen 2025.12.31! Few more attempts later were unsuccessful) before I check it "eventually lost". It was there!!
Took some photos but my attention got on another Waxbill (for sure the Common Waxbill but "strange"!). I took bunch of photos to document the bird, posting just two.

Starting with photos of Japanese White Eye and Saffron Finch. The last photo is how the Common Waxbill should look.

I really like your series. Well done, Isv.

Which kind of confirms what I am saying, 28mm has been the default thanks to smartphones. And now manufacturers want to differentiate. Or do you have another idea for why it might be that there are almost zero 28mm produced?

In the EF mount, Canon made three 28mm lenses over a 30 year period. None of them were L. So far, in the 8 years of the RF mount, Canon has made one non-L 28mm lens. Seems about right.

There were four each of EF 24mm and 35mm, two of each as L, and so far for RF there are two of each focal length, one each as L.

So for wide primes, RF so far aligns with EF, and the EF mount long predated camera phones.

The most likely reason is that Canon knows what focal lengths their customers will buy. 28mm has never been a big priority for them.

I am pretty sure it's canon blocking 3rd party FF RF lenses... with Sigma Art capabilities shown in the Sony E mount I can't believe they just not capable to port their art lineup to RF mount except some financial issues with Canon

Financial issues would be de facto blocking, but it is not the same as Canon not allowing third-party FF lenses under any circumstances.

I’m surprised Canon hasn’t yet produced an RF TS-E. I know it’s niche but it’s something Canon have specialised in. There are so many RF lens but these are absent. I’d love a replacement for the 17mm TS-E. Laowa have one. Ideally I’d like a 15mm one. Autofocus wouldn’t be necessary for me.

I think the market for TS-E lenses is rather small and the EF TS-E lenses work "well enough" for those people who already own them.

If Canon is open to third parties making lenses for the full frame sensors, but nobody is... then likely the contract by which such an engagement may take place has been made deliberately burdensome.

On many such international forums the politics are directed by those who are on the top and dictate the money flow.

The main scientific argument against the Teals being two different species is the "high gene flow". In the same time there are species that are preserved by humans from the same "high gene flow" - to preserve their species integrity. In other words the science is acknowledging their single species identity!
From my point of view the "gene flow" between the Eurasian and the Green-winged Teals is a secondary factor and the reason for this is the character of the mitochondria - with their often circular DNA that is like the bacterial (for me it looks like an ancestral difference!!!)! In other words the mtDNA differences are more significant for me. If there is a secondary, species unifying "gene flow" that is polluting the original genome DNA - it's a different question!

Their genetics is really interesting. You are right, the US Green Teal mitochondrial DNA differs from the European Common Teal by a massive 5.9%. So, the maternal line, down which the the mitochondrial DNA passes, is very different, having diverged some 2.6 million years ago. The nuclear DNAs are much more similar, like 99.7% the same. This may be due to the females always going back to the same place to breed whereas the males travel widely to mate. Interestingly, birds are the opposite of humans for sex linked chromosomes. Whereas human men are XY and women YY, male birds are ZZ and females WZ.

Thanks for these articles. I bought a CF card (expressB) 10 days ago and today I looked and the same seller has none in stock, the goods are expected on April 14th and the price of the goods is 22.5% higher than what I bought.

Maybe a dumb question, but would it be impossible for Canon to take the RF 50mm F1.2L (or the 85mm) USM and "just" replace the USM-motor with a VCM style motor? or is the motor inside a lens so composed that a total redesign of everything is necessary?
