Canon did have a decently successful in the professional market 28-300mm so stretching it to 600mm? hard to say.

it's a niche market for sure. it's one of those - if you can't see the use of it, you probably aren't the target market.

okay but this isn't an F6.3

a 600mm F8.0 would have around an 82mm filter, maybe 77mm

That's my point. Why/who would buy the f/8 lens when decent, less expensive, FASTER zooms have existed for a decade or two?

I keep waiting for the "pro" version of the RF 100-500. That lens is great during the day, and worthless at dusk. The long-rumored 200-500 f/4 would seemingly be that lens.

But as we all know, that lens won't be available until Q3 2023. /s.

but they don't just sit around the table inventing lenses without a reason. there's usually a purpose to the research. there's a net cost to creating a patent application and ultimately a patent.

Oh, I know. In my small company, IP legal costs are a large expense especially since we're obligated to prosecute some patent families that have no real value.

I suspect Canon files a fair number of blocking patents, too.

Well, Canon does have full frame RF 100-500, which is 5x zoom and it's bloody excellent! Obviously, 20x range would definitively require much more compromises, but if the image quality was at least acceptable, I'm sure it would sell well. To be honest, 30-600 is perhaps a bit too ambitious, but something along the lines of old EF 28-300 doesn't seem outside of realm of possibility.

200-800 has awesome IQ on my r5 m2 45 MPs even though it is no L lense.

Even with lower resolution sensors I was never a friend of those superzooms.
Still too big and too much of a compromise in IQ performance.
And now we have >20 MP sensors and not 8 MP.
That was not my idea of a lens when I bought an ILC system.

IMHO we are talking pixel peering here. IQ of zoom lenses is amazingly sharp. I don't see difference between my SIGMA 50m f/1.4 ART with 33 MPs perceptual resolution and thew new Zoom lenses 24-105 f2.8 or for that matter the 200-800m.

Both zooms are delivering extraordinary sharpness on those 45 MegaPixels (MPs)

My Sigma 150-600mm C was plenty sharp on the 50 Mpx 5DSR at 600mm. Only sold it on getting the R5 because the AF was not good.

I'm curious: Do you have the rf 100-500? Because we also used the Sigma 150-600 paired with a 5DS-R. But the RF image quality was so much better than the Sigma lens that the Sigma literally stayed in the closet until we finally sold it used.

I got the RF 100-500mm on day 1 and have posted many 100s of bird and insect images with it, as well as having started several review threads like:

The awesome AF of the R5 and RF 100-500mm for Dragonflies in Flight

We have a fun thread on Dragonflies and Damselflies, enjoyed by some of us aficionados. The most difficult shots are those of them flying as they are very small and fast and usually erratic. So we have developed tricks for photoing them. Recently, the AF of the R5 has made such shots much...

plus more.

I have also posted earlier 100s of image from the Sigma 150-600mm and have started threads on it, including:

Sigma 150-600mm customization

I traded one of my 100-400mm IIs for a Sigma 150-600mm C last Thursday from the local shop after I borrowed and tested it. The Sigmas vary from copy to copy, some have tested much worse than the Tamron. This copy is off-scale at the top end in their quality control. It beats my 100-400 IIs at...

My copy of the Sigma was excellent. Maybe yours was at the bottom end of copy variation.

Quite possible. We even had to do the manual adjustment to fix the focus at all. I'd think that was the fault of the camera, but all of our other lenses worked perfectly on the 5dsr.

Anyway, to each their own. Cheers! And your dragonfly pics are sweet!!

Well, yeah, but to be fair that's only 4x enlargement and it's much easier to make a 200mm - 800mm lens rather than 28-300 (as the old EF version). The patented 30-600mm would have to be either insanely high quality (and expensive) to be really good, or very mediocre to keep the price down. I have a feeling it will be the latter - if it ever appears.

It what universe is this a marketable lens? Sigma has a 150-600mm with a 95mm filter and f/6.3. I have one. It hasn't seen the light of day in years because we have other much better lenses at all of those focal lengths. Sigma also still sell the 50-500mm with an 86mm filter also offering f/6.3. These are walkabout vacation snapshot lenses.

They cost roughly $1,100 and $550 respectively. What would someone pay for an f/8, non-L 600mm lens? I don't see it worth more than $995. Most people on this forum would never be in the market for this lens, and the hobbyist tier photographers would just buy a Sigma. Frankly, most of them cannot understand why we have any of the "L" or "big white" lenses anyway.

Methinks this lens is a thought experiment that never sees first light.

Reading forums i see a ton of people using lenses like the 100-400 F8 with teleconverter or the 800 F11. Not everyone cares about aperture.

this isn't the lens you think it is - are you in the wrong forum post by any chance?

this is a PJ 30-600 lens meant for photojournalists to take anywhere - similar in the vein of the 28-300 EF lens that proceeded it. this lens starts at THIRTY mm, not 100, not 150 and not 200.

Also - if this gets created - and Canon WILL create something like this - it will be an "L" because it will have the body construction and weather sealing necessary for professional use.

and please show me where this lens existed a decade ago - I'll wait.

This sounds like a sidelines sports lens for one of their automated turret camera mounts.

I remember talking to professionals about the 28-300 and they loved it. I never got it or really understood it but they said it allowed them to take out one lens and that was all they needed, and in the field there was no lens changes in bad weather, etc - it just worked.

I think this lens is in the same vein.

there's a certain professional segment that wants a lens like the older EF version. they aren't the types of people that probably visit these forums though.
