phoenix15: Only if Lenovo let the motorola brand alive. Only moto is not enough.

More specifically, Google bought Motorola Mobile Devices, stripped out MMD's patent portfolio for enhanced ammo in the Microsoft/Google/Linux patent wars, and sold the remainder to Lenovo.

PKDanny: DISLIKE Motorola!!!

I like them. I have a first gen Moto G and they have been very good at pushing out the Android updates/upgrades.

GotoDengo: DPR, shouldn't you add a "NOTE:" to this story indicating the results appear to be hampered by a sub-par lens, and a substitute is on the way?

Your comments make that clear. It needs to be in the story.

@Thematic

No. According to the Zeiss USA website, Otus is only available in Nikon F and Canon EF mount.

Joe Ogiba: Smart idea of Ricoh using the older 36mp Sony sensor to keep the cost well under $2K. Too bad Pentax did not have 4K video mode with H.265 like the Samsung NX1 to increase sales but it looks like most Pentax users are not interested .

Going with an older sensor and getting 4K video is simply not going to happen.

I did note Pentax got the video data rate almost up to the AVCHD max. spec. and the audio sample rate up to 48 KHz, both big improvements.

DoubleDash: Kodak and Polaroid. Very true. IPhone one #1, ridonculous.

The fact that a computer is not on #1 is just shamefull.

@Roland Karlsson
Yes, there were computers before the transistor, but none of those would fit in a house, much less under or on your desk.

Robert Zanatta: Pretty good battery life.

Is like to try the viewfinder.

But only USB 2.0?

I noticed that also.

I am going to assume that on the smaller APS-C bodies space is at a real premium - and the USB 2.0 connector is undeniably smaller.

For fastest import of media, I would remove the card from the camera and stick it into a USB 3.0 card reader anyhow. Purpose built hardware has a way of being faster than what is built into most cameras.

very appealing but shoot for two hours and you could have bought this -

You just nailed why this Kodak product is such an epic fail.

Marty4650: And now... the elephant in the room.

$75 for 2.5 minutes of low fidelity video. Making it into "high priced motion lomography."

Is this a serious tool, or just another toy for hipsters?

It's a serious tool for removing money from hipsters.

Mssimo: I think the number 4 is thought to be unlucky in Japan if I remember correctly. Maybe that is why the skipped D400 name. No idea why they kept D4 and others.

And there is also the Panasonic GH4.

In reply to:

Francis Sawyer: I was going to applaud Kodak for creating this somewhat perplexing but bold product... until I saw the price. The price for the camera is too high, but the price for the film is PREPOSTEROUS. Why in hell would anyone pay that, when most people have no way to project film and the included scan isn't going to be as good as what you can shoot with a BlackMagic Pocket Cinema camera?

This whole thing is baffling.

Not only will the included scan not be as good as a Black Magic Pocket Cinema Camera, it won't be as good as a Panasonic GH3, a body almost half the cost of a BMPCC.

RedFox88: So this will be a sony camera (sensor ) with a k mount.

You do realize many, maybe even most, of Nikon's camera have a Sony sensor? I don't think that makes them Sony cameras.

If it isn't K-mount, then Pentax likely just went bankrupt.

What would you like to see from a full-frame Pentax DSLR?

Available for purchase.

They announced that it was nine months in the future, now it's another six months in the future, at this rate by the time it is released its time will be passed.

In reply to:

Earthlight: This is really good news for starfield shooters. I will start saving my pennies for this camera and a metabones adapter.

With this resolution, DR and lossless RAW this cam will serve me for a long long time. The only thing that worries me is battery life, but I can probably plug in a USB power bank and be set for loooong sequences in cold climates.

Something like this? https://vimeo.com/125775652

Create: All the Canon and Nikon fanboy neurotics are at it again, 4 Sony cameras in the top ten, and yeah i know about clicks.

@vesa1tahti
What makes that funny is Nikon uses Sony sensors, as does Pentax.

In reply to:

chse: If you ask yourself why Sony is using that lossy compressed RAW, the answer is simple:
Money.
50% guaranteed compression lets you
- use older or cheaper components towards external memory
- use exising designs (save development cost) towards external memory
- use a bigger sensor - say 42MP instead of 24MP - without to much effort
- look better in the continuous shoot department
- sell the same cam under a differnt name as "professional" version

That sounds good except to take advantage of the higher quality 2K & 4K video recording modes of these new cameras you are required by Sony to buy newer SDXC U3 memory cards.

For cameras at this level there is no excuse anymore for using 7 bit offset compression schemes. Even in a Rebel there is little reason for these kinds of tricks. Storage space is not the issue it was 10 years ago.

Steve in GA: Let's say you're on vacation, as I was recently in New Mexico. And, you have your wife, daughter and granddaughter with you. And, you're visiting one of the absolutely spectacular sights that NM has to offer, such as El Malpais National Monument.

At the natural bridge in the national monument, the clouds are moving across the sun, periodically changing the lighting. You want to get photos not only of the natural bridge itself, but also photos of your family enjoying the experience of being in such an exotic location.

That's going to mean that you're going to need to focus and expose on different elements in the scene. Sometimes people, sometimes the sky, sometimes the rocks.

Making your DSLR go through its paces to get all this done, and done well, is fun to me. I don't know, maybe I'm just an old nerd that enjoys making a complicated machine like a DSLR do what I want.

CaPi: This article raises a point: We enthusiasts are willingly being exploited. The rest of the population isn't willing to be part of that. I currently take part in a metal cruise. I carry primes.. Zooms .. the works. The mix of bad lighting indoor misc scenes and daylight scenes when on trips takes it all. I have a list of new stuff I believe I need. The other participants humor me and use their top of the line phones. Guess who has pictures up first? The use apps that let them process and post in only two steps. Me? I get to stay up late and fire up a notebook to post process. Guess who will se the difference when posting pics on web? Only us enthusiasts. No one else. Why pay for the nose for gear and software and be a mule carrying it all over the planet? That's the killer for this industry. Use case driven development wins the day. Gear for the sake of fractional improvemt is only for us camera romantics

kdt82002: I still use P & S because I find smartphone pictures to be inadequate when viewing on 23+ inch computer screens. A phone picture can be noisy and even a little out of focus but still look "great" on a phone screen. Bring it up on a big screen and its flaws are revealed.

This is a big reason I instantly upload NOTHING to the internet. I like to review EVERYTHING I shoot on a big screen, do a little sweetening of the image (If I keep it at all) and then maybe upload it.

I think the real reason the camera market is cratering is DSLR's have gotten really, really good. The huge upgrades in resolution & dynamic range are no longer there to be had. Most folks, even at the high end, are basically happy with what they have. So the camera market is doing a fundamental reordering from buy the latest-new-and-improved to the buy-when-it-breaks model.
