davetj_uk: You can get an App called Camscanner for free for android/ipad that will scan in pdf or jpg.. it does a brilliant job as well.. Camscanner straightens your pictures, and crops out any unwanted space.. I wouldn't lug that QromaScan thing around with me to copy photos and I cant believe anyone would want to pay for such a thing.. I could knock that up with a bit of strong cardboard and use tissue paper as a diffuser for a table lamp or natural light.. $35... You got to be kidding me!!

well, I have no need for this product but it doesn't really matter if it's made out of cardboard, aluminium or carbon fiber...inside the box are LEDs which should ensure consistent illumination and color temperature and that's what makes it kind of useful...

Esign: Wrong, wrong! If you have kept the old negatives, there's still amazingly more information and quality to get out from them than you would believe when looking at the faded cheap prints, even when they were fresh new. I have scanned thousands of mine and others on Nikon scanners, and when corrected and enlarged, many times it’s like you see the pictures for the first time. Sadly, really good scanners like Nikon are no more. That’s really a pity, because I don’t think that the baby boomers was in time ten years ago to take the old negative boxes out for handling. Now, as retirees, comes the time and interest.
Compared, this Smartphone toy is a joke.

well, this is not really targeted at the people who would spend hours trying to get maximum detail out of an old print using some high-end scanner. It's a quick and user friendly solution that will suffice for many but of course not for everyone.

How much time would you spend on building your own before shelling out 35 bucks? And your tissue paper solution probably doesn't offer the quite clever voice controlled Exif data tagging of the Qroma...

BigBen08: 20 bucks per iPhone. I wonder how much each sensor costs Sony.

if you do a bit of google searching maybe you find a way to hack into their internal costing :)

Just a Photographer: Its a large marketshare but it is actually less then I had expected it to be.

come on, any more than that and it's what you'd call a monopoly :)

Randy Veeman: Relying on fickle competitors is not the safest thing.
If Apple or Nikon decided to switch suppliers, Sony would be in trouble.
Samsung on the other hand (who has a slightly less but similar market share) relies less on its competitors and can get away with using Sony sensors interchangeably with their own in some models.

According to the WSJ article Samsung has a 15% market share which is quite a lot less :)

On Apple investigating dual-camera telephoto system post (3 comments in total)
In reply to:

Mister Roboto: I am guessing it will have 2 minuscule sensors. 1/3.x and 1/5.x and will take advantage of crop factor to extend or widen the coverage. Just a hunch, don't take it seriously. =D

Or they could copy again Samsung and make K Zoom-esque smartphone. =D

well, if they do what's described in the patent application, it's definitely not going to be a K-Zoom clone. To be honest I find the idea quite appealing and should not be too difficult to make it work.

On LG G4 puts focus on the camera post (77 comments in total)
In reply to:

nerd2: It's funny so many people are fooled by LG's marketing lies.

-Sensor itself is the same size and MP as note 4 / GS6 (1/2.6" 16MP)
-Aperture is hardly any faster with G4(f1.83 vs f1.9, or 0.15 stop difference)
-"IPS Quantum" LCD is just IPS LCD with fancy brand name. It is hardly better than other IPS LCDs in terms of color/brightness/contrast and clearly worse than latest AMOLEDs.

Oh and the full manual control support - sounds good on paper, but the sensors lacks aperture control. You can manually control ISO and shutter speed on other android cameras anyway.

LG is hardly the only company that makes the features of their new devices sound more spectacular then they actually are. Nevertheless on paper the G4 looks like a very capable camera phone. Obviously only thorough testing will show if the impressive specs translate into great image quality.

On LG G4 puts focus on the camera post (77 comments in total)
In reply to:

Mister Roboto: Almost there but surely miles ahead than iPhone's mediocre offering. Just put at least 2/3 inch sensor and optical zoom 3-5x in the next iteration.

well, only that a zoom means much slower apertures which won't do any good to image quality...

On LG G4 puts focus on the camera post (77 comments in total)
In reply to:

Photato: This G4 can easily be one of the best Smartphone Camera currently. It Checks all the Specs that a Pro or Enthusiast photographer may want.
Apparently it has the same Sony Sensor as the Galaxy S6 but with an even larger Aperture at f1.8 and better 3 Axis OIS (the S6 has two)
But probably a more important Spec is the dedicated WB sensor which helps with great accurate color, something that can be seen at any image size.
The Quantum Display with its Wide Gamut and high resolution rounds the whole package.
I don't care about the Leather Cover though, it looks tacky and ultimately doesn't protect the Screen, I'd rather get the Plastic version and cover it with a protective TPU case that wraps the Screen Bezel.
Oh and Removable Battery and SD card !
I don't think there is nothing LG left out here.
If so I'd like to know :)
I hope the DPR staff here can see the value of this and make a review of this tech marvel.

Fully agree, and it is very frustrating but we'll keep working on it :)

Certainly would love to review this but, believe it or not, LG is actually making it quite difficult for us to get hands on their devices. We'll definitely find a way to review it at some point but unfortunately I don't think we'll get one of the early review unit...

yes, there is.

muvovum: and once again Oly gets the medal for being the first to introduce the hires mode, when they weren't the first ones. AFAIK it was Hasselblad.

Who? Me? I work for Dpreview and have never owned an Olympus camera, although some of them are actually quite nice :)

Mister Roboto: One can only hope that it will work and not just another marketing BS. 7 camera modules, each with microscopic sensor.

Take a lowlight/High ISO shot and you will end up with 52MP painting. If one lens got broke (lucky if it is in the corner) then you will have a gorgeous picture with a hole. =D

Why can't we have more CM1-esque cameras? One camera module, one large sensor, happy user, no marketing BS.

sure, agree, but the number of people for who such a camera is good enough if a lot larger than the number of people who really need the IQ of a CM1 and are therefore happy to live with its larger dimensions and willing to pay a higher price.

thinner and cheaper than the CM1...and by the way they sell infinitely better than the CM1, despite the inferior camera....

because the CM1 is bulky and expensive and therefore only attractive to a niche audience (in smartphone terms). Ultimately manufacturers want to make money with those devices and that's much easier with slim at more affordable ones. I would not slam this technology before we have seen any samples. After all, some of the multi-frame technologies we have seen in the iPhone 6 or Google's HDR+ mode are quite impressive and I would expect them to get better with time.

On Apple buys camera-technology company LinX post (74 comments in total)
In reply to:

neo_nights: [OFF-TOPIC]
@Lars (or anyone else at DPReview) - Few weeks ago I've looked up for any info about a successor for the Lumia 1020 and, apparently, Microsoft will abandon the "big sensor" route because it was a niche market and Microsoft realised that it'd be better for them to do just like everyone else.

Do you have any info on that?

all a matter of cost though, at the end of the day manufacturers need to shift huge numbers of those devices to make the development worthwhile. Niche products that only appeal to a small number of users and are expensive will always be a difficult sell internally I think.

I have no hot info on this but a while ago I spoke to a Lumia engineer who said that a lot of customer feedback they got for the 1020 was that the camera was too slow which of course has at least partially to do with the large sensor.
