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.

AndreSJ: DP2 Quattro Hands on review 160+ comments. Sony a6000 hands on review 67 comments. im very surprised

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".

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.

In reply to:

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.

gl2k: Most customers who buy P&S or "pocketable" cams have no clue about technology and don't care about image quality.

They simply buy what the shop clerk recommends.

Yes that is why the Sony RX100 is such a failure.

Oh Wait....

In reply to:

iudex: This is in my opinion the closest to a perfect CSC. Body as small as M 4/3 cameras, but with an EVF (and the best one, with 2,4M). But this would mean nothing (other NEXes are small too) without ading a perfectly suitable collapsible zoom lens. The biggest disadvantage I critisized on NEX cameras was the disproportion between tiny camera body and big lenses. Nos the power zoom perfectly accompanies small body, making the NEX6 + 16-50 PZ the smallest APCS camera with a zoom lens. Of course physics cannot be cheated, thus we must accept the f3,5-5,6. On the other hand starting at 16 mm is perfect, making the 16 mm pancake obsolete. I am not a Sony fanboy, but I say BRAVO!


Sony did everything right here.

My biggest complaint:

No detents on the control ring.

I can't even stand using a mouse wheel without detents.

In reply to:

attomole: I think Nikon and Sony have hit on the right size of sensor for this sort of camera,

As ever comments are about what it doesn't have, lens is a bit slow at the long end compared to F X10, which would work toward levelling the performance advantage of a larger sensor.

build one with flip out screen and an optical VF to make it a prober street photographers camera and i would be more interested.

Point and shoot have to do something camera phones are swallowing up there market

I think Nikon showed us how good this size sensor could be, but Sony actually used it in it's proper setting.

The moment I read about Nikon 1, I thought, great sensor, when will it get a proper home (in a compact, built in lens camera).

IMO this sensor is too small to bother putting in a ILC. Once you start swapping lenses, pocketability is out the window and there is no other point to go this small in a sensor.

With Sony it finds it's perfect home, improving the image quality of true pocket cameras.

In reply to:

AndrewG NY: DPReview did this camera a bit of a disservice with sloppy scaling of their side-by-side with K-5. If you compare pixel measurements with the hotshoe and lensmount (which should be identical with the two cameras), you'll see the K-01 is oversized a bit -- in reality it's not quite as big as it looks next to that K-5.

I did a transparency crop overlay of the hotshoes, they look the same to me.

In reply to:

rjx: I think people really interested in this camera should turn their focus on the Canon G1 X instead. Or if they insist on interchangeable lenses, the Sony Nex cameras are hard to beat.

But I feel these small interchangeable lens cameras are a waste. You still need a bag to carry it and the lens's and accessories around. IMO an entry level DSLR is the way to go. You get a nice viewfinder and you won't sacrifice quality and features to save a little size and weight.

If you learn the proper techniques of how to hold your DSLR while using, the strain is none to minimal.

For transportation purposes, buy a great quality bag with a nice shoulder strap. Take a look at thinktank bags.

IMO these small, sleek interchangeable lens cameras are a gimmick.


I would really like to see Nikon put this sensor in a fixed lens compact camera. That would likely be a good compromise between camera size/quality.

You could then build a much smaller than G1x camera, with better quality than micro-sensor cameras.
