The worst thing about this is that they removed the hand grip

Mdopp: For the millionth and certainly not the last time...

This camera is equipped with a 10,9 mm to 34 mm, f/1,7 to 2,8 lens in front of a micro four thirds sensor.

To recreate the same image on a full-frame sensor, the same effective aperture (aka entrance pupil) and the same field-of-view are required.
Here, the effective aperture is 6,4 mm to 12,1 mm and the FOV is 113° to 90 °. The same effective aperture and the same FOV can ONLY be obtained on a full-format camera with a 22 to 68 mm lens that has an aperture-number F3,4-5,6.
Simply put, this camera and lens ARE NOT EQUIVALENT to a 24-75mm F1.7-2.8 lens as stated in the title! Such a lens would have an effective aperture of 14 - 27 mm. On a full-frame sensor, IT WOULD BE MUCH BRIGHTER! Besides signal amplification and noise, also depth-of-field and diffraction blur would be much different from the Leica camera and lens.

So the equivalent lens for a full-frame sensor is really only a 24-75mm F3.4-5.6 and nothing else!

No, the title says: "24-75mm equiv. F1.7-2.8" which clearly states that the focal length is equivalent and the aperture is actual.

Debankur Mukherjee: any news on the iMac...........

I doubt we're going to see the next gen iMac anytime soon. Apple know that a top spec Coffee Lake processor iMac would step on the toes of the base model iMac pro at a fraction of the cost.
You could go for the new Mac mini with the 5K LG monitor instead, but then you're lacking a dedicated GPU.

ekaton: No innovation, no hybrid VF, no IBIS, no grip, 24MP just for the sake of...........? I remember the market share Leica targeted to gain following its affair with venture capital some few years ago. With the Leica M product strategy a pipe dream. I have all these lovely m-lenses and the M9 as the light box to attach it two. Still waiting for innovation from Solms, like back in the day, when the M9 and X1were announced and really made a difference. Am still a Leica fan, but no longer a customer.

@ekaton Seems more like 3000 comments a day

Oskar P: More proof A mount is dead and forgotten. Sony again shows they don't care.

They don't care about A mount nor their customers.

When I attended a Sony eve6in the summer, the rep repeatedly told me to switch to E mount. He didn't even try to say A mount had a future.

Sony put out an a99ii just to please existing A-mount users even though it was obvious that A-mount had reached the end of the line. There was no good business or financial reason for them to do this, so don't tell me that Sony don't care about their existing customers.

Cameras should be designed by engineers and scientists, not lawyers.

Clint Dunn: It's an interesting idea with one major fault...at least for me. When someone critique's my work I always look at their portfolio....if they have good work and obvious skill then I tend to take their opinion seriously. If on the other hand I see poor compositions, a lack of artistic vision, and all around poor photography then I tend to dismiss those opinions.

In this case since it is anonymous there is no way to filter people out this way...

I don't agree with that at all. The appreciation of art and the creation of art are two very different skill sets. e.g. You don't need to be an expert painter to be an influential art critic.

vFunct: Why would you want a critique from a random person instead of a critique from a photo editor?

The opinions of the people who are going to be viewing the photos (i.e. the general public) can often be more insightful than the opinions of an elite group of "experts" who make up a tiny percentage of the population.

dpthoughts: This cam with its tiny fixed wide angle, has no justification aganst good contemporary smartphones.

"minus much slower, tiny, cheap lens of only f/2.8 rather than f/1.5:"

The lens of the Ricoh is bigger, more expensive and gathers more light overall.

"minus cheap sensor without BSI, whereas good smartphones such as the S9 have BSI sensors these days:"

Absolute nonsense. BSI or not, the efficiency of a tiny smartphone sensor is still well below that of the APS-C Sony sensor.

"in darkness: The GR III doesn't have a flash"

That what the hotshoe is for.

"including the negative effect on candid shots (much less inconspicuous than a smartphone)."

The GR looks like a cheap 1970's compact film camera. The latest Samsung or iPhone does not make you more inconspicuous.

"The eventual advantage..."

Any decent photography enthusiast can shoot RAW and edit photos to give better results than a smartphone.

Correction: 20x sensor area is > 4 stops advantage. So a 3-4 stop advantage overall.

pro photo 2011: The Fuji XF10 has already set a price low bar at @$499.

The XF10 has a built-in flash while the GR III won't have one.

The XF10 has a pancake 28mm f/2.8 lens that barely extends when the camera is switched on, making it truly compact when ready to shoot.

The XF10 also has a touchscreen.

And it has a snapshot mode that can be set at the press of a function button. In this mode, the focus is preset at 2m @f/8 or 5m @f/5.6.

So other than IBIS, what can the GR III add to the feature set to demand a higher price?

Remember it won't have a built-in flash.

Oh, and the XF10 has a microphone input port. I don't know if the GR III will have this feature.

The Ricoh has a sharper lens and base ISO 100.

1) An APS-C sensor is about 20x the area of a smartphone. That's more than a 3-stop advantage. So even with the small lens, the GRIII still has a 1-2 stop advantage over a modern smartphone in low light. Factor in sensor efficiency and it's more like a 2-3 stop advantage.
2) The GR III has 24MP and a lens capable of resolving a lot of detail. A smartphone sensor and lens doesn't come close to that.
3) The GR III has massively lower base ISO noise. Even in bright sunlight, smartphone images have smudged out fine textures and details due to noise reduction.

If you only ever view your photos on a smartphone and you can't be bothered editing, then a smartphone camera is ideal, but view your images on any decent computer monitor, and the image quality just doesn't cut it.

Saaaaaaad: Sure it's zeiss batis, but $1300 for an F/2 lens is ridiculous.

@HowaboutRAW
When did I say the lens is not going to be optically good? Try actually reading comments before replying to them, or maybe consider going outside and taking some photographs instead of wasting your time here arguing over nothing.

MannyZero: It seems to me that those guys at Ricoh G III will be back at the drawing board...

The GRIII is a pocket camera. The ZX1 is the size of a DSLR.

The reviews will determine what the lens is worth, not the specs. I'd gladly sacrifice 1 f-stop for lighter weight and better image quality.

In reply to:

janist74: Ok, the bear photo maybe shows, that one lens is a bit sharper than the other, but it also shows, how pointless is to carry an f4 vs f5.6 lens. The background is virtually identical for a simple mortal humanoid. True, you get more light for focusing, but with the today cameras this does not seem to be a real reason...

If anything, I'd say the PF had slightly smoother bokeh, but there's nothing in it really. Neither lens is particularly good in the bokeh department in this comparison.

It looks sharper than the F4 lens, at least in that comparison shot. Maybe it is worth the money after all.

noisephotographer: After the Canon Eos R another camera with no progress jn computational photography...

Artificial intelligence is the way forward for photography, but many enthusiasts are too arrogant to see that. People don't like to accept that machines will soon be able to do a lot of things better than humans.
I believe that it won't be long before cameras will be able to do a better job than humans of selecting settings & focus, then post processing the final photograph. This will leave the photographer to concentrate 100% on composition, lighting, interacting with subjects etc. IMO, this is what creativity is all about, not fiddling around with buttons and dials then spending days post processing on a computer. I know a lot of people here will disagree with this.

Aaron@Utah: Wow remember when everyone was complaining about having large lenses on small mirrorless bodies (ie sony's) and here canon releases a 1430g 28-70 f2 and I thought my 15-30mm tamron was massive on my A7II (which it is btw) but this puts that to shame for massive lens on a mirrorless

They will undoubtedly release a 24-70 f2.8 in the future

On article DPReview TV: First thoughts on the Canon R (353 comments in total)
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?

My A7R3 stops down when focusing. In theory this should make it more accurate as it compensates for focus shift at narrower apertures, but in practice I've found that the AF can be a little bit off when shooting landscapes at f8 for example. I think the problem is that the AF system has difficulty calculating where the sharpest plane of focus lies due to the deep DoF of the lens when stopped down.
