Then I don’t understand why you replied to my post, since I didn’t say anything like that. If someone said that you should reply to them.
As a side note to your second point, what evidence do you have that the two existing big whites are much less popular than the one you want? And how does the existence of two other lenses prove that Canon could have released a third lens by now?, since you probably aren’t privy to their sales data and manufacturing capacity.
1) Seems pretty obvious to me: "Overall, I'm hard pressed to think of a commonly used focal length that isn't available either in prime or zoom form. If someone thinks the lenses lineup is "very limiting" they aren't trying very hard." I do not agree - trying hard is simply not a solution if you do not have the right tools.

2) Canon notoriously does not talk about specific lens sale numbers. However, there are far more user reviews on popular photo sites and at large photo stores for the 300mm than the two others. There is also no comparison in the number of pictures posted online between the three. So in addition to more anecdotal evidence such as discussions in photo forums etc. we have very strong evidence that 300mm is by far the most popular of the three.

3) I trust the last comment is written in jest.

The 300/2.8 is a ‘cheap’ great white so it makes sense that it’s more popular. IIRC, in an interview Canon indicated that the RF 400/2.8 and 600/4 were developed ahead of schedule based on requests from professional photographers.

I remember this too

Hopefully they release lightweight alternatives like they have been doing for the Sony E-mount. It seems like a lot of their lenses are heavier than Canon's native EF lenses.

My EF 300 f/2.8 ii works well with a 2xTC and EF to RF adapter. Agree that is was "cheap" compared to other great whites in that era. I am not anxious to change this to an RF mount, were it to be produced. I wonder if others feel the same way and suspect that's why Canon has not yet done an upgrade.

I get decent results with my Signa 15mm f/2.8 EX DG. Worked fine on my DSLR but now, using it on the R5 with an adapter, I need to use MF and shut down IBIS to get clear images. Fortunately, was able to set up a Custom Mode for this so now I just need to remember to move from M to C3 (actually made a label for the lens case :rolleyes:). Although the EXIF transmits and although the lens works with AF (slow and really hunts a lot to fix on a focus point), do wonder if a native RF lens would do a better job. But, I think the Fisheye demand is relatively small so I am not holding my breath.

Interestingly he also said once Canon issue a licence, Sigma will offer a service to convert certain Sigma EF mount lenses to a standard RF mount.
!! I hope this is true! I just got the RF85 1.2 and manual focusing is somewhat sloppy - not as bad as the Sigma 70mm Art - but sloppy compared to all my non focus-by-wire glass. To convert all my Sigma Art glass to RF would be wonderful!

Since you state that "the evidence shows", then please show the evidence that Canon has gone to court (or tried to) in China and got ignored or refused.

LEGO (the toy building brick company) have successfully taken Chinese copycats to court and won. First time was around 15 years ago. Note that I didn't say that China has become 'perfect', has become a 'rechtsstaat' or that it treats foreign and domestic companies equally. I'm only saying that China has gotten 'better' over the last 10-15 years. (there's possibly an argument somewhere for the statement that they couldn't any get worse).

A lot of people claim things like "China does X" or "China is Y" when they have in fact never set foot there, haven't worked there, haven't spoken with the people, don't speak the language, and don't understand the culture. That includes some fairly well-known journalists and self-proclaimed 'China experts' in the US and in Europe.

I'm not an 'expert' on China in any way, but I have lived and worked there for 2½ years and can speak/read and write a bit. That probably puts me ahead of 90-95% of everyone else.
I spent a year there working in factories; not corporate offices. I also am not an expert, but I avoid buying anything made there and I have yet to buy a Chinese lens. I did buy a Nisi ND filter and found it to strongly red-cast images.

I am sure some Chinese lenses are unique. In fact, the 'Venus Optics LAOWA Argus 33 mm f/0.95 CF APO' intrigued me until I looked at the poor resolution wide open. Why design a lens of that aperture that cannot be used wide open?
