About me:

Richard graduated as a scientist but had a lot more fun writing and shooting for his university magazine. A number of years spent variously as a reporter, writer and editor on science and engineering titles combined his knowledge of science with his interest in images and words. But it was spotting the connections between emission spectra, white balance and all the nonsense he'd taught himself playing around in Photoshop that helped kindle an interest in digital photography. Searching for a camera led to him discovering DPReview and Richard was recruited by Phil Askey in 2007. He's been combining his love of photography, communication and attention to detail (pedantry?) ever since.

He has unusually strong opinions about lenses for the APS-C format.

henrikbengtsson: Did Canon get you drunk or did you hang out in the bar "taking pictures" of drinks? :-)

I'm pretty sure Chris is joking about being drunk.

In reply to:

wcan: In the video it was lauded that focusing is done wide open. I get this from a max light point of view. However, I believe it is also true that for many lenses, the focal point varies depending on the aperture setting. So if the lens is focused wide open and the picture taken stopped down, you would not have optimal focus. Therefore, aren't there times when you would be better off focusing at the aperture you would be shooting at?....is there a way to make this camera operate that way?

That's what we've always assumed to be the reason why everybody doesn't just focus wide-open. There's a question over whether it's possible to compensate for any focus shift, perhaps by storing correction factors based on shooting F-number and measured distance (it's exactly the sort of thing camera companies tend not to talk about).

That said, some brands seem to get it to work, so...

lehill: I think I'm the only photographer in the entire world that gets really pissy because mirrorless cameras will only use built-in LEDs for flash focus-assist in low-light situations like night clubs or wedding receptions instead of the traditional unobtrusive red grid. How does this new Canon R work with flash focus assist? I see a built-in LED so I'm getting all pissy again.

I love that it focuses with wide-open aperture! Whoo-hoo!

It's one of the things we planned to test but ran out of time.

And you're not the only person who gets wound up by it: it's a constant source of frustration for Rishi, too.

The on-camera light is red on the EOS R (since Dual Pixel AF means *all* its pixels, including red-sensitive ones, are contributing to AF), so there's *some* hope.

In reply to:

PhotoKhan: The touchscreen is laggy...?!?!...LAGGY...?!...Oh, Rishi it so shows you don't use an M camera...tsk, tsk, tsk...

So that users here are not misinformed, let me put the record straight.

Canon touchscreens are extremely responsive and precise, making them one of the best, if not THE best in the industry.

Being able to partially map the touchscreen for AF point selection and then swiftly and precisely choose the required AF point with my left thumb (...yes, precision with a thumb... that's how good Canon's screens are...) is my single most valued atribute on the M5, operationally miles away from the imprecise and difficult to operate joysticks on my current (5DMKIV) and previous DSLRs.

My only concern was that the solution wouldn't be migrated to the R line and, now, I can be at ease about it.

Since I have a production camera in my hands and have just checked, I'm going to reinforce what Rishi said.

The system is well designed, as you describe, but it's not terribly quick. I'm using relative mode and particularly with a small autofocus point, found I couldn't always get the point to move in time to capture the moment I wanted.

jpr2: I've been searching (in vain) for more info on that lens/adapter control ring - so, thank you for these comments.

As a possible RF-mount user - of three decades EF glass collection and history - so despite the cam being disappointingly fugly, and... no IBIS, it is not yet entirely off my radar.

OTOH it is light years ahead of that most lame Eos-M system joke, as unlike most of us here I'd gladly prefer this MILC to be APS-C instead of FF.

Thus the clarification that ring controlled RF to EF/EF-S adapter at $200 will be mandatory is a very welcome bit of news :D to clear my mind. Completely agree about placing the ring up front on lenses is bizarre and outright weird!!

There's a less expensive adapter with no control ring if you like. It's simply a question of whether you want the control ring (your lenses currently work fine without it).

In reply to:

ecka84: This EOS R doesn't seem like a professional camera at all, but the whole thing (specially the F2 zoom) is really too expensive for normal people. It seems unbalanced. If I'm going to get one now, I'm probably going to use EF lenses on it. And if it turns out to be a bad idea, then I'm not getting one, for sure (Hello Sony :D). I wonder if Canon is going to sell it with the RF35F1.8 IS Macro as a kit lens (I mean cheaper than separately), for those of us who don't care about any standard kit zooms. And are they going to produce any affordable UWA and telephoto lenses, or this is going to be a system for wealthy people? With European prices, paying €3000 a piece is just nuts! And the F2 zoom will probably cost around €3500.
Otherwise, not bad, Canon (compared to 6DII).

I think you're right to suggest the camera body that's been announced is an odd match for some of the lenses.

On that front, Canon did make clear that this was the first body in a new range...

Dr_Jon: Apparently when power is off the shutter covers the sensor to keep dust out, which is good, but there is a 1.7x crop in video, which is bad. Any news on if the 4k is available in H.264?
(Also no camera price, just bundle with lens.)

Yes, it's H.264.

Adam23a: Does the 4K video have a crop? Some reports say it does.

Yes, 1.7x crop.

In reply to:

Dima_467: And some silence conspiracy about 4k crop. Dpreview Guys, why do you continue this intrigue ?

It's literally the first thing we tested when they let us near the camera.

1.7x crop and maybe *slightly* improved but still not good rolling shutter.

In reply to:

ladyjanegray2106: In going from the sensor on the LX100 to the sensor on the LX100ii, the individual pixel area has been reduced from 17.56 µm² to 11.09 µm², about a 1/3 loss in area, hence light gathering ability per pixel.

Now, I have the red-dot version of the LX100, and it has an amazing ability to pull detail out if shadiws (in RAW). I love what that camera can do.

Does anyone have any idea how the LX100ii compares? The pixel area is the same as on the Olympus Pen F, which in my informal amateur tests seemed to have a much more limited ability to handle underexposed regions.

There's no ND filter (that would have required redesigning the lens) but there's a filter thread to let you attach an ND or Vari-ND.

No word on dust-proofing. Again, the use of the same lens would strongly suggest it hasn't become any more dust-proof.

tampex: 1800 second shutter speed? Wow, that must be a mistake? I could not find the user manual for this new camera, but the previous models (by user guide of LX100M1) longest shutter speed is approximately 120 seconds in T-mode.

We're told the maximum is 30 minutes (1800 sec) rather than the 2 minutes of the existing model.

In reply to:

M H S: Of course DPR already has the camera/lenses, and is hereby confirming the rumor. Otherwise, they wouldn't publish this, and risk looking like fools.

Unless you consider the opposite case, where we don't publish this: 'DPR isn't saying anything about this widely-discussed thing, therefore they must be under NDA, so their silence confirms the rumour.'

Rumours are rumours. You can't assume more than that.

Dibyendu Majumdar: Hmmm I guess DPR wasn't told about the new camera/lenses? Else we wouldn't hear about it, right? There was no mention of the Nikon Z leaks here.

The key word in that sentence being "guess."

sunjester: All I can say is wow at that misleading graph.

...they can offer at least f/2.8 aperture for ***per-unit-area*** light gathering purposes. (equivalent aperture values also describe light gathering).

tbcass: A very informative article everybody should read.

It was intended to be just that but I'm not sure the status of the second article.

In hindsight, I think we probably should have listed it under 'opinion' so that it didn't seem to be an educational piece, and chosen a headline that made clear that it's ISO that's the problem, not people's level of understanding.

Generally the size of individual pixels makes very little difference when you look at the whole image.

We'll see how they compare when we get a final camera.

In reply to:

aut0maticdan: I think the s35 here looks quite nice but I’m not loving the full frame clips. Even the Prores stuff looks lower quality than the D850. I’m seeing artifacts as if it were over sharpened and/or underexposed and pulled shadows up (one clip is clearly under exposed without correction). Nikon could have provided some better light, lol.

I use -7 sharpening and a custom logish profile on the D850, so it could be that, but the s35 here looks really good, so not sure. The final FF clip also looks decent. The AF looks pretty awesome overall.

Footage. I really hate my phone.

Nukunukoo: Also wondering if the new DJI Ronin-2's Pull Focus will work on the Zs?

I guess it'll depend on whether DJI can reverse engineer the protocols, but it would be a shame to move to focus-by-wire and then not give full developer access to that feature.
