SimenO1: Advantages of in camera DNG:

- Saves the conversion step in post processing

- Bypassing a proprietary format makes the files more avaliable for unusual software

- Bypassing a proprietary format potentially reduces software cost (licensing)

- We don't have to wait for software updates to support raw files from a newly launched camera

In fact, Canon should have made DNG an optional raw format long time ago, just like Pentax, Leica and a few others.

@dtibi: Please Don't call snap-shooters photographers. And it doesn't take away the advantages I mentioned for us who are.
@itguy08: There is no doubt DNG supports more OSes and more software then proprietary raw formats, even if you count dcraw.

Lotzy: I want foveon type sensor, curved, with global shutter, with 16 million usable ISO and non mechanical lens aperture... Please?

And a teleport button to travel around the world in between work and dinner. :p

I hate ruin a wild fantasy with reality, but here it goes: Moire-sensors are a dead end. They cant be used with real light, only monochrome (i mean laser-kind of monochromacity), and the resolution will suck forever.

Also the usable 16M ISO are ether breaking the laws of physics (normal sensor sizes) or breaking the bank (mousepad size sensors).

Also curved sensors will render all your current lenses useless.

That said, GS with analogue memory-tracks will revolutionize dynamic range and enable us to choose exposure time locally, in post processing.

Fujica: Once global shutters become affordable the DSLR will be an ancient tool like film loaded cameras are today.

Why do you think GS sensors wont be used in DSLRs?

Why would GS end the endless discussion on what type of finder they prefer?

SimenO1: A 2,87mm f/2,8 lens that equals a 20mm full frame lens also equals f/19,5 in full frame terms. This is a ridiculous miss on the claimed target. A fraud!

tkbslc: They should use their camera phone with larger sensor size and larger aperture in stead, and take a swipe panorama shot.

WIMorrison: Looks like another nail in the coffin of that once magnificent firm that invented the digital camera, I bet they wish now that they had buried the idea very, very deep where no one could find it.

Kodak is dead and buried long ago. Even the brand name are sold. This is not the once great company, but them who bought the name.

On article Mobile Speed: Portable SSDs for photographers (204 comments in total)

This method requires a PC as a middle man. There should exist solutions to avoid dragging along a laptop, but still have a large backup in case the camera is lost, damaged or stolen. Preferably wireless for continuously backups without the wire hassle. A battery powered Wifi NAS with the appropriate compatibility with wifi cameras.

SimenO1: 1. While raw are important for photographers, its not for the snapshooting masses, so I predict raw will remain a little used feature. Phones are snapshot-machines, not photographic tools.

2. Modular solutions are to complicated for the snapshooting masses. And you have to specifically remember it, just like a real camera. So I predict this trend will die.

3. I predict multi lens cameras will become a big thing. Expect 4 lenses soon and 16 within 3 years. The configurations will vary a lot.

4. Algorithms are extremely important for multi lens cameras. This will be a huge investment and effort for a long time.

Priorities priorities. The phone I had ten years ago didn't have room for a larger screen then 1,8". My current phone have found room for a 5,2" screen (more then 8x the area). Normal camera modules (1/3" sensor) are as small as 10x10x5 mm so it doesn't take more then 4x4 cm and 5 mm deep to house 16 decent camera modules. Batteries frequently takes at double that volume.

In reply to:

grasscatcher: I posted below about how I think this tech might start to show up in standalone cameras I thought it might show up in the highly-competitive m43 market first, and then in bridge superzooms.

After further thought, I suspect it may show up in he bridge super zooms first. This is because they are also a highly-competitive market, and have smaller sensors to work with. Smaller sensors = faster image-processing speed.

Yes, the computer processors are getting faster, but they still put out a lot of heat. Bridge cameras may offer better solutions for heats inking, plus less heat generated from their smaller sensors.

Also, I can see implementation on some enthusiast compacts where dual sensors (one being monochrome/IR) can offer unique capabilities, including 3d and depth-mapping.

Speaking of new vs old technology, we are still using round lenses with square sensors. When will we get round sensors? Software already exists to automatically rotate the resulting round image to right-side-up, or wherever you want it. No one will be able to complain about corner softness anymore! :)

Never, circular sensors will never be as cost efficient as rectangular, but we might see more of the multi aspect compromise. Larger diagonal then image circle, but smaller short side then the image circle. This will use more of the lens image circle then usual without the need to choose a larger lens. The latter is a key factor. Maximizing IQ with minimal camera+lens size.

In reply to:

photenth: As long as physics can't be broken. The size of the sensor and the size of the lens pretty much define image quality. Sure cell phones catch up, but the same tech in a larger sensor/larger lens will result in better IQ. The question that should be asked is, at what point is the difference not visible. Dual cameras won't be better than a single large sensor with an equally large lens. The idea that interpolation and noise reduction based on higher sample rates across different smaller sensors instead of one larger sensors will solve that problem is delusional.

Area of the sensor + size of the lens elements is the real measure of image quality.

Array cameras for 1" and larger sensors dont make sense in terms of size and portability. Array cameras for sensors smaller then 1/2" does make sense because you will improve noise by averaging without making the device unreasonable thick. With 4 lenses we can remove the CFA and have a single color filter for each lens, and thus avoiding moire effects without low pass filters. That will increase IQ quite a bit for phones. With at least 6 lenses we can get moireless sharp images with stereo depth as well. It doesn't make sense to use this technique with system cameras, so phones will get unique features and advantages compared to system cameras. With 8 lenses we can get IR enhancement of images as well, or use the last lenses for PDAF only, to receive better depth information. Or use some lenses for polarizing information or HDR or different focal lengths or pixel densities. A phone can in theory fit 50+ lenses to achieve various goals. Algorithms will of course be extremely important.

In reply to:

EskeRahn: The best approach for stuff like this would be some sort of equivalent to 'spoiler alerts'. Optimally with a text in the cover up that in a few objective words describes the content. e.g. "Historical picture, children after Napalm attack"

That is, let the content be there, but without explicitly showing it until requested.

This COULD (at the least in theory), be combined with some parents-filter, that could set an account to not show the 'problematic' pictures at all.

In Denmark there have been several examples of people having stuff banned that was showing some images from the Hippie period.

Why? This was safe enough to print on the front cover of a newspaper and throw it on president Nixons office desk. In work hours. Children see and learn about this image in primary school. Why shouldn't they see it on screen as well?

Thomas Traub: what should we learn from this step: that facebook is controlling what goes public and what not - that's a massive intrusion in information-liberty. As "sozial platforms" controll the information we get or get not they controll our information and also our opinions ........ very very suspect!

@RedFox88 Why should type of ownership define the ethics of censorship? Ethics should be independent of ownership.

samfan: Whether we call it censorship or not, I always wonder what is the point of the policy in the first place. What the hell is wrong with nudity?

Why is the society so terrified of as much as a naked breast? Or wait actually it's not even the whole breast, it's just the nipple that the nasty part, I guess?

Wait, no. Anything even mildly, potentially suggestive is deemed a no-no. I work for a web company where we host some user content so we often have to deal with threats by Google that they'll pull their ads. One such case was about pantyhose. PANTYHOSE. Not even any special sexy sort, just a regular showcase of stuff that's available for purchase so the ladies don't get cold in winter.

I guess that's at least one advantage of living in Eastern Europe. We don't get afraid of that stuff. We get boobs plastered all over regular magazines and web sites and yet we don't murder each other or throw excrements at each other.

THERE'S NOTHING TO BE AFRAID OF FACEBOOOK, GOOGLE ET AL.!

Facebook and many other sites are very American in their thinking, possibly driven by a weird and strong religious force. Horrifying violence are considered OK, but innocent and non sexual nudity are considered filthy.. Even this iconic image, is considered to have something sexual about it. A nine year old girl in a life threatening situation! Their minds must be very sick to even think that way.

Its on time this becomes a general debate over there. Not just for FB. I think Europeans have a much more sound view at nudity vs violence.

So cool appearance and size! I would love a lens like that for landscapes and street/architecture. Vignetting is sometimes nice but also easily correctable. Only the price and mount stops me from buying one.

I hope someone will make something similar in specs, but without the Leica pricing. For instance a Pentax D-FA 28mm f/4 Limited.

In reply to:

mr.izo: i guess nikon wants to scare costumers away with their price policy..

I think their logic is like this: "Sales numbers are halved the last x years - We need to double the prices in order to keep up the revenue".

And Sony are not alone with that logic. Just look at high end APS-C DSLR prices now vs before. Or even smaller sensor formats. But medium formats have become cheaper. The price gap is smaller now and have caused an increase in MF sales (and probably will the next years too, helped a by Fuji GFX and Hasselblad X1D)

In reply to:

SimenO1: Only 4 stops VR stabilization, isn't that quite weak for a new lens to be sold for the coming X years? The competition are already at 5 stops 5 axis.

@mgblack74: For some genres of photography I agree about the 1/400s argument, but a 70-200 can of course be used for much other things then sports. 5 stops is better then 4.

In lens stabilization fools the human balance system to think you hold the camera stably, even if you don't. The visual system are one of the two inputs to the balance system. Conflicting inputs between the inner ear and the vision ultimately cause car/sea sickness. Using an in lens stabilization system gives a mild effect of car/sea sickness and reduces the effectiveness of the stabilization system slightly.
