It's very possible that Canon will take the current R8 mechanicals, remove the EVF and package it in a Video focused "V" style body shell. Job done. Does it need a R6III sensor? Probably not.

A 20-70 (or even better 24-85) f2.8 VCM in the pricerange where the 35/85mm f1.4 VCM lays would be very interesting. Especially if it will have IS aswell

I too lean on the R8 V because the C-complement for the R6 is the C50.

So I was wring - for me a strange idea to have R6 iii, R6 V and C50 as three flavours of one basic camera "segment".
But knowing Canon a little bit from the last 40 years: They have done it several times ...

The RF 100-500mm is an order of magnitude or more better than the EF 400/5.6. It is sharper at 500 than the prime at 400, has excellent IS against its absence, faster AF, will focus close and had all the advantages of zoom for framing as well as longer with little extra weight. I’ve used both extensively and the zoom is indeed not close, it is miles ahead.

I used to have the EF 400mm f/5.6 and regretted selling so much I bought another one I it was very nice but the huge MFD is a major drawback and then I bought the RF 70-200mm f/2.8 Z and it's noticeably sharper with the RF 2x for 140-400mm f/5.6 and a MFD of 68cm so I've sole my EF400 again
A new RF 500mm f/5.6 would be nice but I'd rather have a zoom

I've used this setting for volleyball matches, never thought of trying it during snowfall. I was in Yellowstone, Grand Tetons, and Rocky Mountain National Parks the entire month of February, shooting lots of wildlife through the snow. This info hit the forum a few weeks too late!

Honestly, if the 300-600 f/5.6 L is either never happening or $12,000 USD, I would be happy to have this lens instead. Does anyone have an expected price? I'd imagine at least $5-6k, but that's a lot more forgiving than $11k+

It's a slippery slope. This was my first DSLR bird picture, with a T1i and EF 100/2.8L Macro, after looking up while walking around shooting flowers.



Clearly not enough focal length, but then I came across a used EF 300/4L IS for sale and bought that.



I sold the 300/4L IS (for a bit more than I paid) after getting the EF 100-400L, then I upgraded the T1i to the 7D and that was my birding combo for several years.



But then I bought the 1D X and needed more reach, so I got the just-released EF 600/4L IS II and the MkIII TCs to go with it. Full circle on the red tail.

She and her husband author a popular series of birding guides, and she told me that her usual setup was the EF 300/4L IS with the 2x TC, mounted on whatever the current 1D was (IIRC, it was the 1DIV at that time). She said most on the images in the Guides were taken with that setup. Clearly, it’s capable of producing excellent images.

Very cool.

I'd love a 500 5.6 and a TC for similar, although I'm more about deer, bears, and standing herons where I am:

With my 300 + 2x combo for birds, it's pretty good for casual shots of kingfishers, sparrows, junkos, etc. as those you can get close enough to when they're sitting on posts or fiddling about in the grass. All very printable. Alas, my R6 blackout in the EVF sucks for rapid bird movement tracking with this lens and tc combo. It's funny, because it felt great years ago before mirrorless.

But all that stated, my general photography tends to capture people, large animals, and still life anyhow so I haven't been too eager to drop real money on the extra reach with other life interests at hand. Yet. The itch is growing.

I'm hoping a 500 5.6 at a price competitive with the industry (e.g., Sigma's edition) would give me the excuse — I might even plan a trip around it. IQ's never an issue for me when I do things right, but I find the 300 + 1.4 is solid for animals in terms of servo drive, etc whereas the 2x on a gripped R6 lags a little more than I'd like (blackout, lack of power for the lens drive, etc.). I know I could flip to an R3 or R1 and get way better lens drive (tested with a friend) but I'd rather spend on glass as in most respects the R6 still serves me well.

In the modern sense I find little issue with the IQ of the combinations — it's more lens performance around AF, weather sealing (no mount gasket), and the like. Of course, newer lenses at the same or better tiers have that much better IQ — and I'll take better over good — but for relative prices the options don't seem so much better that IQ's the only thing needed to drive my justification. And since I like using primes more than zooms, I've held off on the EF 100-400 II and RF 100-500.

For now, I'll live vicariously through you guys while waiting.

I thought it was funny But changing a setting seems easier than changing camera

It has to have CFExpress B to do any of the 7K and raw codecs, but perhaps just a single slot.

If this camera doesn’t have IBIS, I think it will struggle. I use my R6 III way more than my C50 for video because it has IBIS (I like fast, manual focus primes). A big reason for the FX3, S1 II, and ZR success is that you can keep them small and handheld because of the IBIS. Plenty of ways to differentiate the R6V from the C50 (handle, XLR, timecode, cooling) and R6 III (EVF, mechanical shutter) and still have IBIS.

Not to sound dramatic, but I used the ZR and was blown away. The 4" screen should be mandatory for any video-focused camera going forward (nice work, Kinefinity Vista).

Click to expand...

I also use fast manual primes; and shoot a lot of film professionally - but grew up obviously in a different era as a camera sits on a steady support (panning film head), a slider or a gimbal if I need to move. I actively would not want IBIS. And I don’t know any filmmaker that works alongside me using a film camera with IBIS. Perhaps thats why professional cams from Canon have not up to this point included it. We don't use it…but that’s not to say things will change and peoples approach will change. Too much youtube people crying on about IBIS I reckon.

Interesting patent. If this were a 600 mm f6.3 I would be more enticed to purchase (or a 500 mm f4.5 with 1.4x TC built-in). Even a 400 mm f4 DO with built in 1.4x TC would get my interests. A straight 500 mm f5.6 not so much.

I can't speak for the original 300 f/4.

I'd consider one of those too. But if you're looking for several framing options then a 500 5.6 and a 700 8 aren't a terrible combo for daylight shooting.

And yet I have been surprised in the real world before. Not arguing, just acknowledging that on-paper has not always translated to real world effect in my experience. And Canon is starting to do, ahem, interesting things with exit lenses and distortion handling on purpose. Whether that might impact a telephoto lens design? You say not really, but I point at the VCM primes and Canon interviews and go, well, weirder things in the name of good have happened. And since I don't own a 200-800... and since the 500 is a prime... maybe. Just maybe.

I have an EF 600/4L Mark III, which I bought to upgrade my previous 500/4L II. The problem isn't weight, it's bulk. The 600 is awesome for working from a hide or another fixed position with reasonably nearby parking, but it's too big to fit in a conventional backpack along with the other things you need for a wildlife day away from the car.

Indeed, and it wasn’t a valid extrapolation. The point of the 24 vs. 200 comparison was that the distortion of a supertelephoto lens is minimal compared to a wide angle lens, prime or zoom.

"Canon's RF line-up is missing the 500mm f/4 lens from the EF days. With how much weight Canon has shaved off of the 600mm F4 L IS USM over the years, I don't think there's a need for a 500mm F4 in the line-up.
Going with a 500mm f/5.6 prime would cover both of those lenses from the EF days."

This is an incorrect pairing. The lens released in the 1990s as the other half of the choice set with the 400 f/5.6 was the 300mm f/4. Both lenses were amateur-oriented products. Both were designed without solid compatibility to 1.4x and 2x teleconverters to reduce development costs, keeping the price point lower. They were similar in price, designed for film cameras, allowed screw-on filters that amateurs used, but their entrance allowed the buyer to choose between slightly greater focal length or slightly higher aperture. Both sold very well for over ten years as Canon sales swelled between the mid-90s and the mid-00s.

The 500 f/4 was a professional lens for those who shot large mammals at closer range, auto races, and the like. It was a weight tradeoff with the 600 f/4, had similarly high weather sealing and drop-in filters, and it was designed for teleconverter use. It seemed to me like the press corps in particular liked to rent the shorter lens on an as-needed basis.

The proposed lens design is likely to be an amateur-focused design like the old 400 f/5.6 and 300 f/4 were. But a lot has changed since then. Older amateurs have more money and are pickier about lens quality, in line with other aspects of the large Boomer-ish demographic (I think the 800mm f/11 was a flop with them). Amateurs today seem to think more about lens weight than in the past. The costs to design a lens compatible with teleconverters have dropped as computers do the heavy lifting. I'm guessing this is a pure cost and weight play relative to the higher-end pro lenses, and that there is only enough amateur market today for one such lens. If the 400mm focal length is chosen over the 300mm length, it suggests than Canon's market research arm concluded that people today preferred reach over an f-stop.

I'm asking here for this lens for years, thank god!! Make it happen Canon!!

I loved my EF 400mm 5.6L and never had a lens like this again! (no, 100-500 L is not close).

Click to expand...

EF 5.6 400 is a great lens except
→ missing IS
→ 3m close focus limitation
→ relatively large size

But it excels in clarity, weight and good diameter for firm grip. Clarity presumably is a consequence of low lens/group count!

I would be so into a 300-600 5.6 that would hopefully be a decent weight.

That was the point...you stated that you would rather have a supertelephoto prime than a zoom, and indicated that the distortion correction required for your wide angle lenses was one reason.
