Leandros S: Under what terms are you using these images? You're a commercial site, and commercial use is not permitted by the copyright holder (Val Klavans for the retouched versions). Your versions are on the rather large side to be claiming fair use.

According to the comments on Valerie's Flickr stream, she's been aware that the pictures are here on dpReview for 36 hours. So, unless you're her legal representative (in which case, it's disingenous for you not to admit so) you're fighting a battle for another adult who did not ask for your help.

Oh, and as far as your notion that processing a raw file qualifies as creating a "derivative work", you have a lot to learn about IP law.

tkbslc: Your sample images presume the width of a square and a 16:9 display would be the same. However, generally monitors are priced per area, so a square monitor with the same area as a 16:9 monitor would be 75% as wide, but 133% taller. So your horizontally displayed photos get smaller, but your vertical images get larger. It's a nice compromise, but it also ensures nearly every photo wastes about 1/3 of the screen space instead of half of your photos wasting half the screen space.

The other issue is that movies just look better on a wide format screen. It's not even really a debate. Companies are saving lots of money by converting to all one aspect ratio and that's looking to be 16:9 all the way.

A consumer grade (or even image processing professional grade) 1:1 screen will never be built. The photographers who want one are too small a number. Most people want a general purpose web browsing, word processing, video watching, image viewing computer, not a specific "slide show" workstation.

As you decrease quantity, prices soar. So much so that it's cheaper to simply mask a 24 inch (that's 21x12 inches) LCD down to 12 inch square. A lot of image viewers can do that already.

Again, you cite an incorrect example of why something was done, in order to support your arguments. The e-reader was created for a multitude of reasons, including cost, size, weight, and battery life. It's no more "glare free" indoors than an emissive display.

Oh, and once again, humans have an oblong visual field, so no, "consistent image size" is not "important to shutterbugs" at all. Maybe on some other planet, but here on Earth, pretty much everything that has eyes scans an oblong field.

Your assumptions are fatally flawed.

It is natural for vertical artwork to be smaller than horizontal artwork because the human visual system (eyes, positioning muscles, and the brain running it all) works on a basically rectangular field. The larger the display, the more applicable this is.

You talk about the broadcast industry designing things systematically. That's also incorrect. The broadcast industry adopted their near square 3:4 format because of physics: it was easy to mask onto round CRT displays and vidicon camera tubes. Once they had the freedom to cut glass in any shape they wanted, aspect ratios increased.

144 square inches of LCD weights about the same and costs about the same whether it's a 12 inch square or a 16x9 rectangle. Which do users prefer? The market already voted 3:4 and 4:5 off the island.

Oh, and I have enough experience with IP to know that your comment about manufacturers not looking at your "invention" is also incorrect.

Actually, Nikon makes some of the finest spotting scopes on the market, advertises heavily in hunting magazines, and even sponsors hunting contests.

Personally, I think Oly's endoscope and camera operations could achieve synergy. Imagine the campaign "shoot the ...."

RoweLee: I hope Nikon would wisen up and do something different-- How about something that has more appeal than that joke 1 system? Nikon used to have a cool rangefinder lineup. What happened to that? A real rangefinder camera at a sensible price would be nice. I'd prefer that over the 1 system any day. Fuji has the X series, Olympus has the PEN system, why isn't Nikon reviving their old S-mount? I'd pick a leica M for its simplicity over any DSLR too bad it costs several DSLR's! What I'd give to see a Digital Nikon S3 or SP...

The rangefinder died (except as a multi-thousand-dollar fashion accessory) because an SLR is a Swiss Army Knife, working with wide angles that require aux finders on a rangefinder, telephotos that you can't even focus on a rangefinder, and macros.

Despite being louder, bigger, louder, heavier, louder, and requiring compromises in the lens design, the versatility of the SLR took the market by storm.

Well, you asked...

AbrasiveReducer: This is the inevitable result of cameras becoming electronic gadgets. I see name brand point and shoots, blister packed at Target. Not saying this is Nikon's fault but it is what it is. For now, they can still make some money on interchangeable lenses and overpriced accessories.

So, how do you explain that 15 years ago, over 50% of pictures were taken with disposable cameras and simple, fixed lens P&S cameras? It's not "electronic gadgets" that are the problem, it's that the high cost of digital temporarily delayed the ubiquitous cheap alternatives, so the camera makers got used to selling $200 boxes, when the masses clamored for the return of the $15 blister pack P&S and the $5 disposable.

The ship has sailed on the camera makers getting that ubiquitous market back, because now "everyone" has a phone that came with a "free" camera in their pocket or purse. Even the $40 blister packed, card fueled phones have cameras.

JPR.lda: No need to change the concept, just implement properly a few things:
1- built in WIFI across the full Nikon camera range, without limitations
2- make Nikon 1, ergonomically compatible with D4, D800
3- make Nikon 1 compatible with CLS flash system
4- make a Nikon 1 top of the line, with a 6Mpx Hi ISO sensor V#x and V#h
5- Articulated LCD

I explain what I mean by the above requests:
1- communications are important, just build WIFI inside the camera, not a stupid adapter at silly prices. In a shoot I need to show the customer the photos on a tablet, or post them i
Immediately for approval.

2- I am a Pro using D3s and V2, each one for different jobs. It's crazy to memorize all the different ways to set the camera. V2 and lens are priced at pro level, so make it easier for a pro to use it

3- I want to be able to Nikon flash and Pocket Wizards

4- there is a D3s and a D3x, I would love a V3s, with better ISO then standard V# and 6Mpx is enough for most jobs

1 - fine.

2a - you're talking about trying to counter smart phone models that sell in the 10s of millions. That's not Nikon 1 territory, and a few hundred thousand 1's won't make back losing 10 million compacts. That's "crazy".

2b - the steep learning curve UI of a pro DSLR will kill them in the 10s of millions markets. Nikon even changes the UI between the D3200 and the D800 class. Trying for an "ergonomically compatible" product line is also "crazy".

3 - not possible with current technology. CLS pulse messages use flashes in the 5 microsecond range. You need the discrete metering cells up in an SLR prism to read that, the main sensor on a mirrorless isn't fast enough.

4 - There "was" a D3s and D3x. There "is" a D4. Lower pixel count only improves high ISO performance when you pixel peep. Higher MP counts are the future. Look at the Nokia 40mp phone on today's front page.

Tim Moynihan: Special thanks to Dave Rubin (http://www.dsrphoto.com/) for letting me borrow his Nikon D800E for this piece.

Ziv, that's not entirely true.

Sure, the Android and iOS operating systems don't support raw, unlike the marginal and useless token support in desktop OS's like Windows and OS-X, but...

Just like on desktops and laptops, what really defines "support" is the apps that process raw files. Multiple raw decoders, including the popular LibRaw, have been ported to both IOS and Android, and there are several apps in the App Store and Google Play that use LibRaw.

Peiasdf: That's why camera with wi-fi is a great idea. Save us $50 and we can use any card. Hear that Nikon, Canon, SONY, Pentax and Fuji?

@Reg, Use an 8 gig card on "any camera"? There are six 24mp APS DSLRs and mirrorless on the market, today. Tomorrow, this card will be scrap.

@Teru, you missed the disadvantages of the metal shrouds that half-surround the SD card slots in most cameras, the lack of power available in the SD card slot, and the size and orientation of the antenna. Like others commented, this thing has a range on the order of 2 feet. Nikon's smaller external WiFi unit goes 10-20 times farther. Oh, and if a camera maker integrates it into a camera, then there's a UI to set it up.

@Pieasdf, artificial price differences abound. There's one right here: AFAIK the Mobi and the more expensive X2 share the same hardware, the only difference is the stripped down software.

Reactive: With something like a Canon EOS 700D, he could have changed exposure settings using a smart phone app, I believe.

I believe you're unfamiliar with the smartphone apps that do the same thing for a D800, like DSLR Dashboard or Helicon Remote.

Although the overall experience is a bit different from using such software on a Canon. For example, the D800 doesn't lose its OTG connections constantly, the way the 5D II does.

gbainbridge: One small thing worries me. Does it allow you to plug in headphones so that you can hear sound with the video? It looks to me as if it blocks the iPhone's mic and speaker.

Yes, the pictures show access to the headphone jack.

joe6pack: As far as viewing 3D video, you can get a scope for just $7 and it is available now.

http://www.amazon.com/dp/B004T7VIPG/

Now for taking pictures and video in 3D, that's where it shines. I would like to see some real samples.

I cannot seem to find any real samples in their webpage. How come???

Also, without the viewer, I suppose the device can be a lot smaller. It does not seem like it is possible.

The only reason you can buy that "alternative" for just $7 is that it's been discontinued for almost two years, and they're selling it as surplus. You can't even use it with last year's iPhone 5, let alone with the new one that's going to launch in September.

Oh, and my3d has no software other than six anemic games, and no photo viewing software. Which doesn't sound like much of a problem until you realize that a split side-by-side stereo pair can't be zoomed or panned in any meaningful way on an iPhone's stock viewer, and it's harder than heck to even flick through images with the my3d thumb holes.

Poppy fits current phones and has viewing and shooting software.

And they're now up to $123,000 on kickstarter, way over their modest $40,000 goal.

About time.

I can't believe that it actually took them two years to realize that "Pentax Ricoh Imaging Company" had about the worst initials of any corporate entity in the entire world.

I'm in stitches. The first time a major player adopts a lightfield sensor (multiple photodiodes behind one microlens), it's not to achieve some pie-in-the-sky dream of a "focus-free" cameras, or the "solution to a non-problem" gimmick of "refocusing" images on a web site.

Nope, it's to improve focusing (more accuracy, greater AF area coverage) for plain-old, flat images that you can't "refocus".

I can picture the next steps: 4 photodiodes behind each microlens, for better performance on either horizontal or vertical detail, then 9 to cover a wider range of apertures and take the coverage up to 100% of the frame.

wildbild: Thank god it's not 24 mpixel! Defraction would have been noticable from f8 on..

LOL. There is only a 10% resolution difference between 20mp and 24mp. The diffraction difference is essentially invisible.

mpgxsvcd: Finally, Canon got back into the game.

"Don't see any "photographic" improvements,"

There is none so blind as he who simply refuses to see.

This sensor points the way to main sensor PDAF that's as sensitive as existing systems, but doesn't depend on two mirrors and a sensor block all being perfectly aligned to achieve acceptable accuracy. Mirror alignment was what screwed up both the Canon 1D III and Nikon D800 AF systems.

And it can cover 80% of the width and height of the frame, instead of 50% like APS DSLRs or 33% like FF DSLRs.

So, if you "Don't see any "photographic" improvements" in having the best focusing system ever, well...

In reply to:

Atlasman: With this technology, Canon will extend the life of DSLRs.

At the same time, it gives them more time to perfect a mirrorless solution.

I guess we can expect little from their EOS M line.

With this technology, Canon can "perfect a mirrorless solution" easier than anybody else.
