Patent: Canon presents some interesting fast zoom lens optical formulas

[LogicExtremist]

I'm sure they have reports back from forums. For example, they will read that we would love to have variable fps for the electronic shutter for the R5. So, they won't implement it with a firmware update and will have it as a feature of the R5 II that we we will have to pay for. Similarly, they won't remove its unnecessary 30 minute limit. Now you might think I am jesting, but many a true word in jest.

I can see that happening, strategic market segmentation, you want it, you pay for it in the 'new and improved' model lol!

I'm sure the R5 overheating saga that saturated the forums, YouTube reviews and blogs must have reached Canon via these means. I can't imagine it would have been solely from tech support calls, as it would be so easy for Canon tech support to cite some official company line with disclaimer and just brush it off. Guessing they get their negative feedback online somewhere!! Perhaps people need to complain more online???

But when gear is "in the wild" being tested, the "substantially correct rumours" are more likely IMO to be intentional leaks,

I am not sure that I agree with that.
Once a product is in the wild leaks are pretty much inevitable.

Would not be surprised if the marketing departments intentionally leak out rumour info

I would be surprised if they didn't.

I would have thought that the pros testing pre-production gear in the wild, would have to sign NDAs in order to get access to the gear. It would be very foolish for them to leak info if that is the case. An onlooker might recognise something as being a new model, but would find it pretty hard to work out the specifications. "Leaks" about specification, once gear is in the wild, IMO originate from the manufacturers, and are part of the strategy to drive up demand. It stimulates pre-orders, and helps manufacturers gauge demand and set production targets.

The whole rest of the world that they are testing in is filled with people who have not signed NDAs.

True, but I haven't seen sensor types, MP counts, frame rates, or any other such specifications printed on cameras. And such cameras would not have a badge or more likely have the badge of an existing camera with a similar appearance (e.g. slap the R3 batch on an R1 being field tested).

Of course not, but the rest of the world don't have the cameras in their hands, and can't know the specifications. The only people with that knowledge are the pros doing the testing, and the people in and outside of Canon who are involved in preparing marketing material. And all of them will have signed NDAs. Think of it like this - once the cameras are in pre-production and being tested, why *wouldn't* Canon be happy to "leak" information and drive up pre-orders?

If you recall the mystery about how many MP the R5 was, pro photogs were spotted using it out in the field but they wouldn't say how many MP it was.
I get what you're saying, at some of the expos they had new cameras in glass cabinets (look but don't touch), but they allowed participants to take photos, so people got an idea of the controls and layout, but no technical specs. I would assume they're not fussed about that part getting out.

Some people like compact lenses.

RF 24/1.8 = 270g. RF 50/1.8 = 160g. RF 35/1.8 = 305g.

Those are all pretty compact. I think Canon has shown they can do compact prime lenses with larger apertures than f/2.8.
