On the camera, Better late than never.

But IMO, lacking a truly desirable lens holds it back.

I would want something like the EF-S, 15-85 F3.5-5.6 or the 17-55 F2.8.

Both seem MUCH better than the general wide to short tele lenses available in EF-M.

I don't care how good the camera is, if it doesn't have a lens I want to use most of the time.

Also, the headline is a bit more like clickbait than usual for DPR.

In reply to:

szhorvat: I am not familiar with such input devices. Could someone explain why they may have chosen this design instead of one where we can draw directly on the screen and there is a real keyboard with real keys?

Free marketing. Every tech site is covering the because of the novelty factor.

I consider it's novelty aspect a negative, but they are still getting a lot of coverage.

notime: I imagine the on-screen keyboard would have more usefulness switching between other languages, especially languages that have more than 26 characters.

On a more powerful system, all of the Photoshop menus, brushes and tools could replace the keyboard, and the screen is just the picture.

The second half is not a second screen.

It's a giant touchpad, with a permanent keyboard image painted/etched on it. You turn on the backlight then you can see the keyboard image. There is no changing it.

LackingCommonSensor: Cameras like this appeal to me in all ways with the notable exception of image quality. For a lower investment, an M43 kit could do as well. That's the rub.

With what set of lenses to match this range?

That question is open to anyone, since so many seem to be saying something along these lines.

M43: 24mm -600mm equivalent with decent lenses? Or the same with APS sensor mirrorless/DSLR.

I really don't see many quality setups, that don't weigh a whole backpack in weight and cost several times the price.

This really does seem like an ideal travel camera.

completelyrandomstuff: Here's something to make customers go 'wow':
50-135mm F2.0 for APS-c cameras. It would be a worthy, and possibly lighter, alternative to full-frame 70-200 F2.8.

It would essentially be just as large, heavy and expensive as the 70-200 F2.8.

Which explains to a large degree why you don't see them do this very often for APS.

The DP2 Quattro has a much more controversial design. So it has more arguing about it's merits.

LiSkynden: Gone is the good old vari-angle screen!
... i would never buy a camera with such complicated looking flip out screen. How do you use it on portrait?

Lets hope they bring the old vari-angle screen back to normal G series now :D

I actually think the new one is an improvement.

I really didn't like the side flip screen on my G6, It always felt awkward to compose on because it's axis didn't line up well with the camera. I much prefer the locked in tilt up/down screens like this one.

RichRMA: The in-focus parts of the shot of the white-sided building look very sharp at 100%. However, the horse looks noise-processed (its hair) at 100 ISO.

Which horse. Looking at the white horse, I see more hard edged aliasing in the hair than NR.

DPR comment areas/forums are quite civilized in comparison to many sites.

Active moderation helps a great deal.

But there is one other huge factor that I have observed over the years. Many of the sites that suffer with terrible comment sections bring much of it on themselves.

In desperation for page hits they post click-bait/link-bait and I would say downright flame-bait stories and headlines. They do this in hopes that they story will be picked up around the web and draw big traffic. Sadly, this tactic often works. But the traffic it draws is often angry about the flame-bait story and is just looking for a fight, so the comment section turns into a Troll-Brawl.

Wired is no stranger to the is tactic IMO.

Thankfully I have never seen DRR do this. Readers come for the solid reviews and editorial content.

Thanks for staying on the high ground, and thanks for keeping comments.

Sdaniella: this is exactly what i've been talking about...!!!

dual-type-pixels (binning), but using a smaller pixel for brighter light and larger pixel for lower light

meaning a 23Mp image is made from 46Mp sensor with 'dual-(small-big)-pixel-pairs'


No, that isn't what this is. You are describing Fuji Dual sensor strategy they have been using for years.

This is not two sensors. It is one sensor, and a simply digital bit of storage to tell when the sensor "rolled over".

In reply to:

Clear as Crystal: Sounds a great idea. Only problem I can see is if the time to reset the pixel is significant compared to the exposure time. In that case the pixel wouldn't gain any extra charge during the reset and this would leave a plateau in the signal before increasing again, giving a lower value than it really should be.
Nothing says it needs to stop at one reset either. If this works consistently it could be a really impressive next step for sensors.

Reset time is an issue, but I suspect it isn't significant. You could also apply a small correction factor to help with that anyway.

You could do more than once, but it increases the circuit complexity per/pixel for what is like quickly diminishing returns except in extreme HDR photography.

forpetessake: This is essentially the same idea as multiple exposures using electronic shutter. For example, you take 4 normal exposures and merge them into a single image, you get 2 times better SNR (and dynamic range) and effectively pushing ISO 4 times lower. You can do it today with cameras like Sony NEX, except the shutter is not electronic, it's mechanical, so there is problem with moving subjects.
On the subject of the dynamic range. The displays and prints have a lot more limited dynamic range than modern sensors. In order to display higher dynamic range you need to compress it, the more you compress, the less natural image looks. Until displays with much better dynamic range are built, increasing dynamic range of the sensor has little advantages.

No it isn't like that at all.

It will just take one normal length exposure. Only what would be the formerly blown out pixels will capture additional info, but it will still be during the regular exposure time.

In reply to:

Karroly: I may be wrong, but I think the idea behind that can be explained as follows :
A photosite can be seen as a bucket that is being filled up with electrons when exposed to light. Overexposure occurs when the bucket overflows.
But filling the bucket is not instantaneous. It looks to me like Rambus brings up a new technology that allows to monitor the bucket level. Then it is possible to empty ("reset") the bucket (and memorize it was filled up once, and maybe more than once) and restart filling it until the shutter closes.
The final electrical level corresponding to the total amount of light received by the photosite is then the sum of as many as necessary full buckets and the last partially filled bucket.
Highly sensitive photosites are quickly saturated. But with this new technology, saturation is no longer a problem.
So the advantages are both in lowlight capability and dynamic range.

Twice the charge levels, is actually only one more bit of storage per pixel and since files sizes are often already deeper than actual dynamic range, no real file format change is really needed.

But files will likely be a little bit less compressible because they will contain a bit more data.

Essentially a counter and reset for the pixel bucket.

Since they call it binary, I will assume that for now, the counter is essentially just one bit.

You can probably do this with just a few transistors, that will trip automatically when the pixel bucket hits full. It sets one bit cleans the bucket, and start collecting again.

One of those obvious in hindsight ideas that should really work out well.

I am just sad that patent troll Rambus thought of it first.

Techo: Re: The screen: From what I've read, the perceived sharpness/detail of the Surface WinRT tablet vs the "new" ipad screens are just that, perceived. Going by numbers alone does not indicate better quality. Us photogs should know that ;) The higher-res Ipad will not necessarily be more readable or look better. Until I see both side by side, the screen resolution numbers is not a con, yet.

What you read is MS marketing making excuses for low res screen.

Wired did a blind test putting screens behind a cutout:
"We pulled up a page from The New York Times’ website that had multiple typefaces and an image, and allowed testers to zoom in or out and scroll the screens up and down to each person’s comfort level. It was a blowout. Every single person expressed a preference for the iPad display. In most cases, a strong one. Multiple people described it as “no contest.”

Peter G: AFAIK this is Surface RT and it doesn't have a stylus capability.

Surface Pro coming around Jan 2013 has that.

Surface RT really should be avoided. It isn't that great as a tablet, nor a laptop and there is little software, and what there is, isn't that great.

That is Surface Pro like Said. It has an Active Digitizer.

Surface RT DOES NOT.

Someone could build an RT machine with Active Digitizer but AKAIK no one has.
