select: nice improvements, but the lack of 4k video, wifi and gps, is a shame for a camera that costs over 3k euros

Wifi and GPS in camera have inherent problems. You generally see these features in entry level and enthusiast level cameras for two reasons. 1) They often use more plastic in the bodies and they aren't as weather sealed, this is adventageous if you're trying to get radio signals through without the use of an external antenna. 2) If the features don't work perfectly an amateur/enthusiast is not going to care as much, the features are still fun. If however you need the features to work consistently and accurately, you're not going to be happy if they fail or are problematic while working on a paying job. Most professionals will prefer to use a separate WiFi adaptor that is more reliable (or use a physical cable in some case). Similarly for GPS they will use an add on antenna that has a clearer line to the sky or they'll use a separate geo-logger that won't drain their camera's battery.

viking79: Go price how much OLPF glass costs, and quickly see Nikon is saving tons of money not including any AA filter at all. Rough guess is a full frame filter is going to cost $100 US +/-.

Seems like a small upgrade, Nikon must be feeling a lot of pressure from the competition to push it out so soon.

It's not just about manufacturing costs (which you're estimating base on purchasing one for yourself through a specially vendor, they're buying in bulk and the price would likely be significantly less than half that). There's a lot of design work that has to go into a new camera. They designed their image processing around the old sensor with the AA filter and with the AA canceling filter, and in both cases with that. They also have to plan out and design the manufacturing line, get regulatory approval in every country they plan to sell it, pay lawyers to file patents, etc. This leads to a cost of million and millions of dollars before they sell their first camera.

Now the biggest issue is that it's practically guaranteed that this camera will not sell as much as the D800 did (because many of the people who wanted a camera like this already bout a D800/E and only a handful are likely to upgrade from a D800). So they have to make more per unit to pay off the development costs.

Retzius: Nice camera. However, I must say the latest releases of digital cameras are getting awfully expensive. Even for an admittedly pricey hobby, the cameras and lenses released within the last couple of years really are pushing the boundaries of "affordability" for the amateur or hobbyist.

Marcelobtp, I agree with you. "Professional" is not a binary choice where this camera is professional and that camera is not. It's closer to a continuum where something like a D5300 has controls that are more designed for an entry level user. For an extra $300, the D7100 is far more professional in it's controls. The D300s has a few features and nuances with it's button layout that are even more professional (though slightly compared to the difference between the D5300 and the D7100), however there are people who will pay $500 more (and take a hit in specs like megapixels, dynamic range, and high ISO performance) for that improvement.

Yes some of those people are just hearing that it's more professional and want it, but most are people who need a specific feature or ability and will pay.

I could get professional results with a D3300, but as a professional that doesn't want the camera to get in the way, I'd probably just be more frustrated with the camera in use.

This is a more "professional" camera, not exactly intended for hobbyists. You can get a very good entry level DSLR like the D3300 for $600 (which includes a zoom lens), or you can get one with more professional controls an autofocus like the D7100 for $1,100. If you really want full frame, the D610 can be had for $1,900 and is a very good high-end enthusiast camera.

To complain this is not affordable for amateurs is missing the point of the camera. It would be like going to a guitar store and seeing the one high-end $15,000 guitar in a glass case and complain that the prices are too high while ignoring the rows of guitars on the wall priced under $500.

In reply to:

bob elkind: Why does the photographer own the rights to these photos?

If the photographer hired the Waltons as models for his photos, and the Waltons signed a model release, then yes -- the photographer owns full rights.

I suspect that the Waltons hired the photographer to photograph them, the Waltons did not sign a model release (why would they?), in which case the photographer does not own the rights to these photos.

Model release has absolutely nothing to do with copyright law. Model releases are only really needed to prove you have the right to use their image (particularly if say you were going to use them in an advertisement).

The only way the Waltons would have copyright would be if they employeed the photographer full time (as defined by IRS laws).

You take a photo, you own the photo. Unless you are employed full time (not on a contract) as a photographer working for someone else. Then that person (or company) owns copyright. Model release has nothing to do with copyright.

If they go ahead with it, then you should be able to get the original files taken at a WalMart portrait studio.

In reply to:

Donnie G: Now this is the kick ass Pentax that I've been waiting for. Not some wannabe medium format pretender dressed in FF 35mm clothes, but the real deal at an enthusiast accessible price point. Ricoh! You done good baby!

But this is a medium format want to be. 43.8x32.8 is hardly full frame and noticeably smaller than real 645. It's a good step, and I'm glad they're mocking Hasselblad and Phase with their ludicrous prices for the same sensor, but true medium format, this is not.

KAllen: You will not need to go a D800 to ask that question.
I don't own MF digital but I would if I could despite all the comparisons people make with the D800 etc. It's not all about the number of blades of grass you can record But I can't justify it.
I wouldn't go the Hassy route all the same, the 1/800th of a second top speed kills it for my needs.

Different cameras for different needs. Our H4D-50MS is great in the studio for reproducing artwork, and blows away the D800. However if I'm going to a show in a dimly lit club, the D800 is going to blow away the Hasselblad. Different tools for different jobs.

In reply to:

stratplaya: Who manufactures the sensor? I didn't find that in the release.

Do you have a source saying with certainty it is Sony. There have been a lot of rumors saying so, but I would like to know for certain. All other sensor that Hasselblad sources for MFD are from Kodak or Dalsa. Phase One seems to be using the same sensor in their new 50MP CMOS and they only source from Dalsa. I can see Sony stepping in, but I'd like to see documentation before I start repeating rumors.

Hate to break it to you. The Hasselblad H line was partly made by Fuji. Look up the Fuji GX545AF.

In reply to:

dynaxx: I am confused ; I thought CMOS used a rolling shutter unlike the CCD sensor that exposes the entire 44mm X 33m frame simultaneously.

How can the H system lenses with their central ( global ? ) shutters work with both CCD and CMOS ?

CCD colours have always been better ( like the Fuji X-Pro 1, the last DSLR with CCD ) so this seems to be the trade-off versus practicality.

Rolling shutter only occurs during video. In the case of still photos (even for cmos) the shutter it turned on before the shutter opens and turned off and read after the shutter closes… no roll there.

"No price premium" except the sensor is physically smaller (on par with the H5D-40 which costs $10,000 less). That's a 1.3x crop vs a 1.1x crop (from 645)

My D800 has USB 3. And Nikon's site claims "High-speed USB" maybe it does.

Aaron801: I know this is a really ignorant question, but I know nothing about this class of cameras... I'm wondering why a camera so bulky and so expensive is only 16mp?

Different cameras are made for different needs. Not all cameras need high MP. What this camera delivers above all else is speed... fast focusing, lots of buttons that give you direct access to a bunch of different settings without having to dig into the menu (it is quite a bit more complex to learn but once you know how to use it, you can change settings very very fast), very high ISO settings with low noise let you shoot at faster shutter speeds in lower light, high speed burst lets you shoot 11 photos in 1 second, letting you get several shots of something moving fast and choosing the best one, the 1080 60p setting records video twice as fast as most TV plays back, letting you do a little slow-mo or playback at normal speeds it at the higher 60fps
for very smooth motion.

I shoot with a $30,000 medium format digital camera that is bigger than this... it's wonderful in the studio and has 50MP but it's horrible in low light and is much slower. Different strokes for different folks.

On article Adobe expands Photoshop and Lightroom offer (628 comments in total)

Ok here's an actual issue I've had, I've talked to Adobe and they have no solution:

I work on the side for a small nonprofit community arts school. We are not an officially accredited school, we just teach classes mostly for hobbyists or artists wishing to expand their range. We only need Lightroom and Photoshop. We are a small program and have 6 computers.

Because we are not an accredited school and because multiple students will be using the software. The only option they offer that we are allowed to use is a Groups option which requires us to purchase the full suite (we do not teach Illustrator or Dreamweaver or Premier) and requires us to have an administrator (which we do not have or can afford to hire) switch the log ins between classes. This is ridiculous.

On article First Impressions: Metabones Speed Booster (355 comments in total)
In reply to:

Timmbits: hmmm... a $60 tele-converter on backwards and selling for $600.

Worth pointing out Metabones makes 2 Canon lens to NEX adaptors: the Smart Adaptor that has no optic but just has the electronics to allow the NEX body to control the aperture, provide power to the IS system, and allow autofocus (though very slow)... that with no optic costs $400.

This adaptor does all that and then adds the anti-teleconverter optics (which is not the same as putting a teleconvert on backwards). Also where are you getting teleconverters for $60? Canons are $450 and even the cheap Kenko's are $150.

My first concern would be that it might lead to color reproduction problems. Foveon has poor color reproduction with certain colors as it makes a hard delineation between where red stops and where green starts and where green stops and where blue starts. The human eye over-laps these colors so there's some green in many reds and some blue in many greens, bayer filters mimic this overlap and have fewer problems with color reproductions. Without seeing specifics I can't say for certain that this technology will have problems, but I have a feeling that it is quite a possible concern.

On article Adobe releases Lightroom 4.3 and Adobe Camera Raw 7.3 (69 comments in total)
In reply to:

SigmaChrome: I find it truly amazing that Adobe still insists on NOT supporting current Foveon technology. Sigma maintains that it has made the all necessary information available - Adobe (for reasons best know to themselves) simply refuses to take it on board. Why? There is a tremendous rise in the number of people taking up the use of Sigma cameras like the DP2M and DP1M - and there would probably be a higher uptake of SD1M users if Adobe took up the challenge. What's stopping them?

It isn't just Foveon. Hasselblad multi-shot uninterpolated images are completely not supported.

They view RAW processing as only applying to demosaicing bayer CFA images. They need to make the system more robust to handle Fuji's more complex layouts (they currently accept the files but handle them poorly) and Foveon and Hasselblad's uninterpolated layouts.

Sigma could also improve things by allowing the camera to shoot uncompressed 16bit TIFF files or DNGs.

In reply to:

NeilJones: And who would actually shoot video at 15fps?

1) Someone who was actually shooting for stills... at 4K that's 8.2 megapixels at 15 frames per second
2) Someone who's shooting video but plans on speeding it up anyway
3) Someone who plans on using something like twixtor to interpolate the frames
4) Security camera style usage
5) Someone who wants to play around with 4K but doesn't want to shell out for a much more expensive camera and set up.
Edit: keep in mind you can shoot 2.7K (a bit over 4MP images) at 30fps, or normal 1080p HD (over 2MP) even faster.

wkay: is dpreview ever going to stop its obsession on toys and social networking? serious photography obviously does not fit into their business model.

I know several people who are making money with GoPros and similar cameras. Not their primary source of income, but offering time laps and "behind the scenes" videos of their main shoots has brought them a little extra cash.
