Robert1950: Still photographer here, video irrelevant. What is the incentive for an R6?

Canon EOS 1DX-III is faster. Best AF is to be seen, but initial reports are positive.

20 Mpix is more than both my other camera's.

pentaust: Nikon's approach to light weight tele is better (500 f5.6 PF), not as fast of aperture than other long glass, yet a nice trade-off weight-size, price. Canon RF 600 f11 & 800 f11 is a bit too much push to the extreme end of the slow aperture. I guess it's designed to lure some wildlife photography beginner into Canon RF mount (since those RF lenses can't be used on a DSLR), who will rapidly feel the need for a faster lens after using those RF 600 f11 or 800 f11. I bet we will find a lot of used RF 600 f11 & RF 800 f11 in the used market after a couple of years of theses lenses being sold (people selling those to upgrade to a faster tele lens). Experience with wildlife photography teach us that wildlife is mostly active in the hours around sunrise and sunset, requiring apertures such as f4, f5.6, f8. I've done wildlife photography at f11 , when using a 1.4x tele-converter on a 100-400 f5.6, stopped down a notch for better sharpness), but that was already a stretch for the ISO.

The Nikon 500mm f5.6 with 1.7x TC is roughly equivalent to the Canon 800mm f11 (850mm f10). Why would you add a TC to the Canon lens? Out of the 2, the Canon will probavbly deliver the better results.

But I agree with the second part of your reply. But as a beginner, you probably don't have the budget (or justification to spend that much) to go with the best lenses.

entoman: Good article but the charts only go up to 200mm, Why wasn't this extended to include popular focal lengths such as 70-300mm, 100-400mm, 200-500mm and long primes?

I'm surprised that no mention was made about balance. DSLR lenses tend to have the larger heavier elements near the front of the lens. They balance well on DSLRs, but when fitted via adaptors to MILCs they often become front-heavy and clumsier to manouevre than native MILC lenses.

@gameshoes: Canon has the RF 24-240 lens which is not on the chart.

So which ones are the best? It's of no use to have 100's of lenses if they are all rubbish. Split it into landscape, portrait, sport categories if you like.

Ripple: Not terribly informative really. Some comments about throat diameter and flange distance and their effects on lens designs and performance would have helped, for example.

@Pather: Where do you get your vignetting figures from, because if I believe https://www.dpreview.com/forums/post/63793836 this post, all of the optical limits vignetting values could be wrong. So if that's your source, then vignetting could be way less serious for a lot of RF lenses.

In reply to:

mikegt: Let's look at everything we still don't know because Canon continues to withhold this information:

1. What the resolution of the sensor is.
2. What bit rates the video will be recorded at.
3. How much rolling shutter will there be.
4. How long the camera can shoot in 8K before it shuts down to prevent overheating.
5. How much the camera will cost to buy.
6. When the camera will ship.
7. What reviewers will find when they finally get a hold of this camera.

It's also important to note that Canon has not shown anyone a working prototype of this camera. They have not shared any sample photos or videos.

Canon fans and paid posters have already proclaimed this as the new king. With exactly zero evidence to go on. How about waiting until this mythical beast actually ships and gets tested by reviewers, before boasting that it will drive Sony and the other makers out of business ?

8K DCI resolution means at least 8192 pixels horizontal. 4K 120fps means rolling shutter will be at most 8ms. Bitrates are not know yet, but expect it to be lower than the cinema series. Rumors for availability is around July.

Really? The lens resolution limit again? I thought that was debunked long time ago.

In reply to:

1Dx4me: but still no price or sensor MPX, except speculation!!!

Canon says 8K with no crop. But is this 8K, 8K cinema, or 8K UHD? The first would mean 44.8MPix sensor, the latter 39.4MPix.

In reply to:

StoneJack: Based on specs, it resembles Nikon Z6/7 (with more pixels). Nikon's video AF might be better, actually, because NIkon's live view now (hybrid AF) is better than Dual Pixel in 4k or more. Also, Z6 has Prores RAW (not sure about Canon and Sony).

@RD: The Z6 does 12 fps, but only 12 bit RAWs. And without live view (you only get to see the shot you just took). You get 5.5 fps with AF and AE.

In reply to:

Thoughts R Us: BTW, let's remember the original post from Canon Rumors that got the whole internet abuzz...because everything in that post has proven to be true so far, but of course more specs are mentioned:

Named the Canon EOS R5
45mp full-frame CMOS sensor
IBIS

5 stops with IBIS alone
7-8 stops of correction when used with in-lens stabilization

12fps mechanical, 20fps electronic
Dual card slots
Scroll wheel added to the back
No touch bar
Liveview/Movie toggle like previous EOS DSLRs
Larger capacity battery, but looks like the LP-E6
8K @ 30fps
4K @ 120fps
4K @ 60fps
Built-in 5GHz WiFi
New battery, but the same shape and compatibility as the EOS 5D Mark IV

So let's take this as our Rosetta Stone. It's proven wickedly accurate so far, as has the Canon Rumors site.

Innovation would be to have some smartphone functionality in de R5 like artificial bokeh for those f7.1 lenses. Night mode with multiple frame shots. automatic beautifying modes for portrait, etc. Eye-AF was a good start. The R5 now looks like they ++-ed every spec. More fps, more pixels, higher res video. Still looking to upgrade my ageing 5Dc with this R5 though, it's a fine camera if there's no real caveats.

thx1138: f/7.1 L glass, how the standards have fallen.

@Memoochi Ah, yes. My bad.

Link | Posted on Feb 13, 2020 at 10:19 UTC

So does the R5 have the 1DX3's AF joystick with the scroll-pad inside? I cannot make that out on the provided images.

Yeah, f7.1 is the new f5.6 it seems. Sad. But still it gives more DoF than f5.6 on crop camera's, so that's nice.

In reply to:

LoSPt1: 8K RAW up to 30fps? Canon is about to reach a new height, apparently.

Or the 30 fps burst feature from the EOS-M6-II, although it's cropped on that camera due to bandwidth/sensor readout speed issues.

In reply to:

stevevelvia50: IBIS at 7 stops in full frame, would mean Olympus could do 10 or 11 stops easily due to the much smaller sensor, the ratio will always be the same! This is a pretty funny Rumor likely started by Sony fan boys who want to see the disappointment when the “real” specs are announced lol...

@dman: I read that as well. Don't remember where.

In reply to:

karliss: The next-gen samsung phones are comfirmed having 8k 30fps / 4k 120fps video.
But that's on a 1/1.33'' Sensor.
Doing that on full-frame sensor does indeed sound like fiction.
There simply isn't any processor capable of handling that much input.

This argument is stated often, but why is that? For 8K you need a 45MP sensor. I see no reason why a 1/1.33" sensor would be much, much faster than a FF sensor with the same number of pixels. The only difference is the physical size. Maybe there's a slight impact because of the length of the datapath on a FF sensor, but that's about it.

Niko Todd: Don't forget to check for oil on the sensor! And AF fine tune your 20 lenses.
If they wanted to make Canon users happy, this camera should've been a mirrorless. They've spent so much R&D to satisfy a bunch of old-school pros, who have never been the bulk of their proffit(!) in the first place, and never will be, while totaly ignoring the people's screams for a9/7r4-like pro MILC. And those are stuck with a handful of allegedly nice lenses and a misserable P&S level body.
The problem with this camera is not the pixel count, but it's existence.

If you like mirrorless so much, just flip up the mirror permanently. It's a competent camera that way as well.

More pity is that they didn’t call it the R1-D1
