On article There can be only one: why isn't the EOS R3 an EOS R1? (578 comments in total)

@Richard Butler: As I said since day 1: this is due to Canon's use of dual pixels. Canon cannot yet compete with the A1 (and upcoming Z9) regarding the combination of high resolution and fast speed.

The R3 is to hold it down until they can--so it is the mirrorless 1DXIII successor:

Canon will reserve the R1 branding for a future camera. I wouldn't even be surprised if Canon even chose to avoid dual pixel on the R1.

Martin_99: Nice approach for both FF and APSC users. Would be nice to also include wider lens specifically for apsc users, eg. something like 20mm f2 for indoor use. Such lens would be probably too big and expensive if made also with FF in mind.
Already released 28mm f2.8 is too narrow and slow for this aplication.

They already have a 20mm F/1.8.

When Kickstarter runs dry, make sure to move over to Indigogo to dupe those "investors" (who aren't "customers") out of their money too before vanishing. Isn't that right Meyer Optik Görlitz? Or Yashica?

It's simple. It's because of Canon's dual pixels. Like I said when it was first announced:
https://www.dpreview.com/opinion/0931673290/canon-r3-what-do-we-know?comment=7968853637

This camera will basically be a mirrorless 1DXIII, regardless of what they say. It will be priced around $5K. And it is a temporary camera while Canon tries to refine the R1 and match the Sony A1 (& likely upcoming Nikon Z9), which is more of a challenge for Canon due to dual pixels. In every way except 45MP resolution, the R3 will already more-or-less be a match--they just need to also do it at 45MP. And once they do, that will be the R1, priced closer to the Z9 & A1.

mu7z: The average price increases are really what's preventing new younger people to get into purchasing mirrorless cameras. 10 years ago you could save up and get a Nikon D40 or equivalent for an affordable cost. Today, e.g., the z50 is 1k$, almost 500$ more than the D40, ~10 years ago. It makes much more financial sense to simply purchase a phone and try to find something used. I suppose the camera manufacturers have identified that most of their revenue come from higher priced items, but who is left to purchase them if they don't have new users graduating from the entry level offerings over time?

What may have happened was:
-10-15 years ago, you could get a D40 with a kit lens
-Then, you bought one and realized point-and-shoot didn't quite do what you were looking for
-Then, you tried to learn photography
-Then, you realized you wanted to try manual mode
-Then, you realized manual mode sucks on the D40
-Then, you wanted background blur or good low light
-Then, you realized your kit lens, with its tiny <10mm aperture couldn't do background blur or low light in practical scenarios
-Then, you realized you needed a new camera and lenses
-Then, you saw how much they cost and became disillusioned
-Then, you saw what your phone could do

Then, you bought a new phone.

Manfred: I am not a video pro but I wonder: Why these expensive Adobe or Apple products when DaVinci Resolve exists ?

Yes, good point. Of the three supported OS (Mac, Windows, Linux), I believe Mac is the only one that supports GPU hardware decoding (I'm not sure about encoding). And Studio (paid version) supports GPU accelerated hardware encoding and decoding on all three platforms.

The free version of DaVinci Resolve does use GPU hardware acceleration for some tasks (example: color grading); while others (eg. encoding h.264) are handled by the CPU.

BlueJakester: When it comes to any business it's usually all about the bottom line. How many non-professional photographers are paying $12,000 for a lens? If sales aren't sufficient there is no reason to keep producing a product. Your opinion may vary ๐Ÿ˜‰๐Ÿ™‚

Volumes or overall revenues are not the bottom line of the ledger, and they don't need to sell the same volume of a $12000 lens as a sharp $500 prime to arrive at similar bottom line. The way this example is phrased is actually "top line" (revenues, at a 24:1 ratio), not bottom line.

The "bottom line" would typically be net profits--and this would likely relate back to units by a factor of more than 24:1 in this example.

But it turns out there's more to it than just bottom line.

There's also something called "strategy." Eg., what if there is--I dunno--say a new mount that Nikon wants to herd people toward or expand customer base within, but for which Nikon also needs to redirect limited resources? Even if it's done at a loss, break-even, or smaller bottom-line in the short term, it might make business sense to do long-term. This is a different type of top line, and it is likely a large factor in Nikon's decision here--much more so than bottom line.

bartjeej: DPReview, when are you going to learn that smartphone cameras' (equivalent) focal length are just as important as with any other lens? You wouldn't announce a new Leica M-mount lens saying it has an f/1.9 aperture without mentioning the focal length, would you?!?

The lens surround says 1:1.9/19. Does that mean it's a 19mm equivalent (main) lens with an actual f/1.9 aperture (so f/5.1 equivalent aperture)? That would be really wide for a main lens.

Or is it 19mm f/1.9 in absolute terms, giving a 51mm equivalent field of view? That'd be extremely long for a smartphone main camera, but also unique and very cool.

Also, there appears to be a second rear facing camera, alongside (presumably) a ToF sensor. Any specs on that, DPR?!?

So "19 full-frame-equivalent-mm" that is also F/1.9?

That would make this somewhere around a 6.8mm F/1.9 lens, with a 3.5mm aperture, or a 19mm F/5.3 full-frame equivalent.

For a reference point, a relatively common lens for high-end phones is somewhere around 4mm F/1.8. So this is in essence improving the aperture diameter by around 1mm, and adding optics & angular corrections to provide a ~double-sized image circle.

I wonder if this is stabilized...

On article DPReview TV: The best $4000 camera kits (367 comments in total)

Chris' approach largely seemed more like "I want to spend $4000 on random equipment" rather than "I have specific photographic needs and a $4000 budget."

This is why it ended up down to:
Fuji UWA zoom + standard-wide prime + slow tele zoom,
Canon standard zoom + standard prime,
Nikon slow kit zoom + fast tele zoom

??
So do you need UWA or not? Tele? What do you plan to shoot? Do you even know before making the purchasing decision?

For example, if the goal is just to find as much of an all-rounder as possible, I personally would have gone with (as a Nikon shooter):
Z6 ($1400) + 14-30/4 ($1100) + 24-200/4-6.3 ($800) + 50/1.8 ($500)

And I know sure there are similar "all rounder" options from all brands. But do you really need a bit of everything, or are you going for some specialized use cases (eg. portraits, landscapes, action, etc.)?

So better yet, first just figure out what you plan on shooting & which types of lenses align to this. Then work backwards from there.

In reply to:

(unknown member): "deep learning" AF is a bit misleading. Once the FW is in the cameras there is no more learning . That being said, I've been reading how Canon has continued to more gather real world data, at a greater pace, since the R5 and R6 came and improving their class leading human and animal eye detection. So I'd expect any new camera from Canon to take another leap forward with AF, and maybe the R5/R6 will get a FW update too.
As far as I know only Canon can track reptile eyes, and other non mammals during stills shooting, as well as the only one who has animal eye detect during video.

Yup. ML is where a bunch of humans look at pictures and "label" them by manually pointing out the eyes (similar to how humans 'select the boxes with traffic lights' in a CAPTCHA image). After enough of these, the machine starts to recognize ("learn") the common patterns on its own, and it trains its own model. This resultant trained model is then tested by comparing its results to more human-labelled images, followed by fine-tuning. This resultant "static, trained model" is deployed to the cameras--meaning no more "learning" on the camera. It's just executing what it already learned. It's read only.

Of course, independently of the cameras, Canon can continue iterating for future firmwares by labelling more images, and a wider variety, and training more distinct models (eg. one model for human eyes, a different model for bird eyes, etc.).

ML is what allows for fast iteration & improvement, as opposed to a programmer manually writing a program to detect eyes.

Gesture: Don't the EVF (mirrorless) cameras have more power demands than OVF ones.
How are the OEMs - Canon and Nikon essentially - handling this.

There are lots of considerations when it comes to battery life.

On mirrorless, the imaging sensor is always on; though most of the time it is in a lower-power, lower-resolution, line-skipped mode for EVF (except when actually recording a still image; and sometimes for certain video modes).

Corresponding DSLRs also have an "always on" sensor--their RGB metering sensor, which is like a low-resolution (<0.5MP) imaging sensor, so this isn't 100% net new for mirrorless. Though it is significantly more than DSLR.

But notably these cameras are designed to shoot lots of pictures in bursts over a few hours. And this type of shooting will typically bring the two type of cameras closer to even when it comes to battery life. I'd expect a few thousand pictures, enough for most sports events.

(At the opposite, lots of viewfinder usage with few pictures actually taken makes mirrorless battery life significantly worse in terms of shots per charge. For example setting up studio shots).

steviewa: I'm wondering if this is the r to replace the 1d an the future r1 being the 100mpx as Canon has said the high mpx will be slightly different body to the r5 so not sure if they'd call it a r5s, we'll find out over the next yr ish

@PAntunes: the simplest solution is usually the best. So my thought again to the question "at what cost?"

Resolution.

@Nature: We don't actually know some basic things, like resolution. So it's possible that the camera is just as fast, performs just as well in AF, etc. But that it does so at 20MP instead of 45MP.

The R5 does compete well against the a1 most of the time, but it does have its achilles heel, and that's in the fringe cases of very fast shooting. Don't get me wrong--I'm sure it's fine and good for most fast shooting. But not quite 1DX level. So, for example, if you don't want the slideshow through the EVF, it does only 8FPS mechanical; or you can shoot at 20FPS but risk rolling shutter & reduced DR/IQ for action shots.

My guess is that the R3 is being released to address these issues--for people who pretty much exclusively shoot fast action. And Canon's dual-pixel means it will have to find some creative way of speeding things up--likely reduced resolution in this case.

SomeGuyWithACamera: This camera is in development, like (NO PUN INTENDED) in its alpha stage... yet 8 users have had it and one currently owns it...

What difference does it make? Even after the camera is out, people will say they own it when they don't. This just points to the inherent lack of complete reliability in any unverified self-reported surveys.

Kharan: Eh. This FUD marketing stunt is too scant on details to be of any use. But the notorious lack of 8K video means that the sensor is very likely under 33 MP.

As has become a regular thing now, Canon are always reacting and coming too late to the party. This might be another fiasco on the level of the original R.

One of the most common mistakes I see in people new to assessing resolution is in equating 8K to a 33MP sensor for a stills camera. 8K refers to an aspect ratio of around 16:9. But the sensors for most primarily stills cameras (like this R3 will presumably be) have an aspect ratio of 3:2. Since the consumer version of 8K requires a horizontal pixel count of 7680, this would equate to a minimum 3:2 sensor resolution of 39MP. Similarly, the (wider) cine version of 8K requires 45MP in a 3:2 sensor.

So it is possible to have a 33MP sensor that is still not enough for 8K. The real minimum number would be 39MP, with a more probable minimum being 45MP. Like the R5. The R5's 45MP resolution is not a coincidence. It is the bare minimum for cine 8K.

It can't have similar video capabilities as the R5 and be 36MP.

In reply to:

beatboxa: This is gonna be 20MP. BSI & stacked makes the sensor faster.
But dual pixels makes it half as fast.

To keep up with the 30FPS like the Sony A1 and probably upcoming Nikon Z9, it's going to have to read roughly the same number of photosites. Or be twice as fast as Sony's stacked sensor--unlikely. So the first one: same photosite count.

So that puts this closer to 20MP. And that's why they called it an R3, and not the R1.

@Revenant On a dual pixel sensor, each row is read half as fast. Rolling shutter does not mean an entire row is read at once--it still means each pixel is read individually. So on dual pixel, within each row, there are twice as many pixels, making it half as fast. In hypothetical quad pixel, each row would be half as fast, and there would be twice as many rows (making it 1/4th as fast as conventional).

JRFlorendo: Sony and Nikon must be sweating bullets right now, especially if this rumored R3 retails between $6500 - $3900. Seems like itโ€™ll out spec both A1 and Z9, weโ€™ll see, rumors could be wrong.

I'm interested how this "seems" to out-spec the A1 & Z9? Sure, seems like a good camera--and most 1DXIII users will probably get it. But that has more to do with incumbency and less to do with specs. And most of the specs are unknown.

I think most specs will be competitive. Speed, AF, ergonomics (subjective), etc.

But I think the way that Canon will achieve this speed is in dropped resolution. This R3 will be around 20MP, compared to the ~45MP sensors in the A1 (and Z9, which isn't generally available yet).

Note the lack of 8K mention, the reference to prioritizing "speed and sensitivity," the fact it will use dual pixels + 30FPS + fast rolling shutter, the fact that it says it sits between the 1DXIII & R5, and the fact that is named R3 rather than R1. The A1 does most of this (and the Z9 probably will too). But neither of these use dual pixels, like this R3 will.
