Yes, but the Nikon lens weighs more than 3kg. So a Canon 600 with built in converter weighing less than 3 kg would be ‘unique’.600 f/4 x 1.4 has been done.

I wonder how much I would use the ART 105 f/1.4 vs the EF 85 f/1.4 with IS that I use for most of my single person portrait shots.Get the Sigma.
How bout something that HAS been done before like a 600 or 800PF lens!
This is not a crazy lens, but rather optical madness!I’d like to see a 24-240 1.0
HarryFilm is already Canon's secret CEO.Perhaps they have employed @HarryFilm as a consultant?
Don’t hold your breath.I am waiting for:
- APSC professional Camera for Wildlife
Probably 1.4x / 2x, but this one has seems the most likely from your list.- Extender 1.5 and 2 times one Unit switchable
That would be a beast of a lens. Probably bigger and heavier than the original 600/4 IS, which was not something easily handheld.- RF 150-600 4.0
Would be nice, but also something to not hold your breath for. Where possible, I have replaced the existing foot with an RRS foot (600/4 II, 100–300/2.8, and pre-ordered for the 24-105/2.8). Those have the additional advantage of a built-in QD socket.- Arcaswiss compatible lens foot
OK, I'll bite. What would you want in an "APSC professional Camera for Wildlife" that the R7 doesn't have? To me, the most important things are the very small pixel size, same as the OM-1, and the small size of the body, also same as the OM-1.I am waiting for:

I had first had that on the article, and then realized with a 100mm front element, that it's simply not ever going to happen.
which is why i changed it to be a 70-135mm
Naaah! We just buy a lot of Canon, Sony, Fuji, Blackmagic, Panasonic, Leica, Zeiss, Matrox, Harris and Arri cameras, lenses and field-production/post-production gear to the tune of about $35 Million USD over the last 20+ years. We don't need to consult to anyone since we now have fully-inhouse designed and built cameras, lenses, software and supercomputing hardware.Perhaps they have employed @HarryFilm as a consultant?
I have one, and it's the only third party lens I've kept. Big and heavy, and the AF/IS don't always play well but the image quality is superb.Sigma had a 180mm f/2.8 macro and launched a version with OS just before they announced the global vision line.
They are hard to find on the second hand market in .nl, so I assume people are happy with them![]()
AND.... I really should mention that Canon and ALL the other manufacturers should go for all-carbon fibre bodies and high-refractive-index optical-grade sapphire-coated Acrylic polymer lenses to reduce camera and lens weight PLUS put in 64 bits wide RGB + Depth channel recording for modern 3D-XYZ AR/VR imaging applications at a minimum of 64 megapixels and DCI-8K video resolutions at 120 fps!Perhaps they have employed @HarryFilm as a consultant?
Corner stretching is fine, until when Canon uses it as an opportunity to design lenses that do not cover the entire sensor before corrections. That is what I meant by cutting corners - literally. Doing that on budget lens is one thing but I find that unacceptable in expensive L lenses.Hyperbole aside, the fact is that any wide angle, rectilinear lens must have the corners ‘stretched’. In film/DSLR days, the only way to do that was optically, and one need only look at the mushy corners of the EF 17-40/4L to know that optical correction of barrel distortion is not the ideal you seem to think.
The reality is that neither optical nor digital correction is inherently better. Digital correction allows lens designs that weren’t previously possible. The RF 14-35/4 uses 77mm filters and after correction at 14mm it’s just as sharp in the extreme corners as the EF 11-24/4 at 14mm, even though the latter has no barrel distortion at that point. That’s a big win for digital correction, in my book. The RF 10-20/4 is also as good as the EF 11-24/4 in the corners, and the former is wider, cheaper, and much smaller and lighter. Another win.
If you want to forego technological advances, best go back to shooting film. Or get a sketchpad and some pencils.
Add in a 135 mm to 800 mm Contemporary and Sports versions of a Zoom lens at f/4 and the money will roll in for ANY mainstream manufacturer that sells such lenses!They need to stop pissing video shooters off and make a 17-55 2.8 update already or something to compete with the 18-35 sigma. Canon is selling a butt load of c70s and the native lens choices could be way better. Will that hurt the c400 sales that much?
