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.

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?

I also wondered if Sony made exclusivity deals with the third parties since they own part of Tamron and for gaming it’s quite normal to have an exclusive release on one platform for a set period of time. For example Sony exclusives like Horizon Zero Dawn were Sony exclusive for years then finally made their way to PC.
You'd only need to make the special not found elsewhere lenses exclusive as incentive to invest in the system.

Nearly 3/4 of the way through 2022 and still eagerly anticipating that 85mm DN Art and 105mm DN Macro :confused:
I see in your sig that you really like primes!

I finally gave in and bought an EF-mount Sig 28/1.4, 1) because Canon is taking forever with the 35/1.x, 2) if 1.x=1.2 it'll probably more than I want to budget, 3) I had the EF 35/1.4 and I felt it was slightly too normal an angle while 24/1.4 was too wide, 4) given the 35/1.x Canon's probably never going to make a 28/1.4, 5) while I had heard this rumor of Sig coming to another platform, I think I heard it did and wasn't RF, so that was the end of that.

I got the 28/1.4 at Adorama for $539 + $50 shipping to Japan + $50 import duty (!) a couple months ago. Still a lot cheaper than buying it at Bic Camera even after counting the resulting "point card points" at their cash value. Note that while this site does mention sales deals on this lens (among others) several times, it didn't mention the sale I bought mine at. I almost was forlornly checking the adorama website again, "knowing" the sale was over, and seeing it again at the cheap price.

As for primes, I'm shooting the 16/2.8, Sig 28/1.4, 50/1.8, 100/2.8Mac, and EF 135/2.0. I do like 85mm but I figure I can pretty much either crop the 50mm or step back and use the 100 or 135. The 16mm and 50mm are always in my backpack and many of the shots I take with the 16mm are meant to be cropped smaller, so in effect I'm using it as the world's smallest 16-35 zoom.

No rumblings from Tamron, Sigma or Tokina?
Whatever disincentive Canon provided them with to not to produce any new lenses on a RF platform that needs so many more lens choices must have been pretty effective!

Rather interesting how all the big third-party players are nicely and conveniently sitting idle (while producing lenses on every other lens mount platform), giving Canon time to release its mostly overly expensive new premium lenses and its new budget/entry level narrower aperture and/or heavily software corrected lenses, limiting choice and forcing RF lens buyers to buy Canon's offerings or go without. Quite a curiosity also how its nearly only Chinese lens manufacturers that are putting out RF compatible lenses. The Canon fanboys and brand loyalits tell us it's purely coincidental, and there's nothing to see here... :unsure:

Who said that? I haven't say anyone say that. All the Canon users I know, and that I see on this forum, see it as regrettable and most likely a purposeful move by Canon.

I am thinking of buying the 50mm 1.4 ART sometime early next year. So I'm sure they'll announce the RF update about 30seconds after my return period ends.
Did you do so? If not, I got a 28/1.4 last month and that's sure to precipitate some action...

Hi SwissFrank, I wish that was the case, please feel free to look up some of the replies to my posts in earlier threads on this topic. I've read every rationalisation imaginable, some so convoluted and improbable that they were screaming justifications for the principle of Ockham's razor - where there are two competing theories, the simpler explanation (which is the one you've stated) is the preferred one. :)

I've was thinking on similar lines, do I buy the Sigma Art 85mm EF lens, or hold off? Similarly, do I try the Rf 100-400mm lens, or will the promised RF150-600mm be a more attractive option if/when it materialises? :unsure:

I'd love an economics teacher to explain canon's strategy, "if your customers want something, don't give it to them, make them switch to other competitors".
