On Nikon D810 Preview preview (1533 comments in total)
In reply to:

lacroix75: I learned great lesson in the past couple years from Nikon, never buy their first release of anything. Case in point, D800 (early on focus issues, etc..) vs D810 (much more refined version of practically the same thing with minor upgrades), D600 (Oil issues) vs. D610 (again cleaned and refined version). So for me going forward, wait for the second pass, i.e., D910 instead of D900 (if there's such a thing in the future)... ;)

I think your both missing his point. Which is wait for the second release of a Nikon product, as the first release will have problems. Don't buy a D600, get the D610. Don't buy a D800, get the D810. Don't buy a D900, get the D910.

falconeyes: I wished people would stop confusing light field and sensor array cameras.

A light field camera a la Lytro is ignoring some physics (known as plenoptics) which severely limits the usability of such devices and makes them unsuitable for the consumer market. Except you are in a search for venture capital and an exit scenario ...

A sensor array camera a la Pelican is the de-facto standard for future high end smartphone cameras and is parameterized to operate in the usable range for the consumer market (about 9-36 lenses all large enough to deliver enough resolution diffraction limited).

This is like day and night. DPR, please stop calling the Pelican approach light field. It is not, even though a limited range for refocussing is an inherent property of camera arrays (you can refocus with shallow DoF determined by the array diameter within the *focussed* DoF of a single lens within the array).

Fully agree.

Also I would like to see a correction to this article. The sentence: "With control over focus, perspective, aperture, and the ability to tilt or rotate the focal plane, light field imaging expands the set of creative opportunities available to a photographer."
The photographer has always had this control! The word Photographer should be switched with Viewer. That's the new part.

On Kodak Pixpro S-1 First Impressions Review preview (182 comments in total)
In reply to:

Artpt: Agreed with other comments on the industry milestone of three companies offering a mix of lenses and bodies in a common format!....a win for consumer choice.

Brand loyalists may not see the benefit in cross competition among the M43 products, but the exchange of common format opens up an entire industry to innovate on other technological aspects....

Pros already use this model to manage multiple aspects of their work but within their camera brand.

Another thought to consider is how fast a company can innovate a product if the R&D works around a known format over innovating the entire format (lenses, bodies, etc). The legacy costs do eat away at budgets and limit creativity.

@Artpt
Nikon did tolerate it. The last Kodak was a Nikon or Canon mount. The SLR/n was nikon mount and the SLR/c was canon mount. The Canon version was really a Sigma camera and not many were sold. However lots of SLR/n and 14n were sold (nikon). Also the Fuji SLR of S1-S5 were all Nikon mount with great DR, used mainly by wedding photographers and some student photo places. However both of these alternatives to Nikon died.

On Sony Cyber-shot DSC-RX100 III First Impressions Review preview (2970 comments in total)
In reply to:

Alphoid: This may seem like a highly unusual request, but please do compare digital zoom in the review. The RX100 is a bit short on the telephoto end. It has a 1" sensor, high megapixels, and a fast lens. A 2x digital zoom would still place it at, hypothetically, identical performance to a 5 megapixel image 1/2.3" camera with f/2.8 lens at 140mm equivalent, or a 1/1.7" 7MP sensor camera with an f/2.8 120mm-equivalent lens.

That's plenty for portraits in most settings if it works well.

"If it works well" is the key question. How does the autofocus system hold up? Do issues with lens sharpness kick in? Is it usable in that mode? Etc.

I fully agree! A 20MP sensor cut to 5MP by doubling the 70mm still should output good 8x10 photos. I would really want to see this.

I find it interesting that the EM1 with a Panasonic sensor gets this feature.

Whereas the older models using a Sony sensor (know to have this feature) haven't got the update yet.

Either the update is coming or the Sony sensors sold to Olympus don't support this feature. Maybe somethings are better with Panasonic sensors, thus the shift in the high end pro model.

On Sigma fixes Nikon D5300 lens compatibility issues article (37 comments in total)
In reply to:

Paul Petersen: This is really getting old with the bullies at Nikon picking on Sigma.
It has most likely been going on for a while. The last round was a lawsuit over supposed patent infringement of image stabilization technologies. Not much ever came of it but it matched up well with the introduction of the SD1 with superior resolution to anything out there at the time. The D800 was the first to beat it.
Now Sigma has been on a tear with their "Global Vision" product line. All pretty much outperforming most lenses at greater prices. Now a new Nikon body makes all Nikon lenses malfunction. Very suspicious. Gotta love the agility of Sigma to get a fix out. It seems rather prescient of Sigma to introduce the USB adapter for their new lenses. They must have saw this coming after past skirmishes and figured Nikon would engage in these games next.
Checkmate to Yamaki-san

Who said Nikon gave the communication protocol to Sigma!!
Sigma has stated they they need to reverse engineer mounts to get them to work. If Sigma was handed the protocol, then I would think they would fix all lenses, which doesn't seem to be the case.

Joe Ogiba: Sigma needs to come out with an E mount version with OIS for the A7, A7r and VG900 or people will just buy the new 24-70mm OSS E mount lens coming out in a few months.
http://www.sony.net/Products/di/en-us/products/lenses/lineup/detail/sel2470z.html

I partially agree. Sigma striping out OIS is silly. Just add a switch on/off. Then the user can decide. Also the price will be the same with OIS removed.
However, I don't think this is a lens for the A7's. You should look for something smaller. But if do buy the Canon version and use the Metabones Electronic adapter. Then you get slow AF, but control over OIS and apeture. (not the speed booster, then normal one).

In reply to:

rikyxxx: 1/16000 silent shutter is great. Isn't awkward that Sony and Panasonic, two companies w/o a photographic history and background, try (and succeed) to innovate more than Canon, Nikon and Pentax?

cheddargav, your too hard on Olympus! I would say the EM1 is an amazing camera. And including the EM5 sensor in small EPM2, EPL5 and EP5 cameras offers a lot. Also looks like Olympus is starting to release the lenses we want in M43rds!

Pentax on the other hand is having some troubles.
Nikon and Canon just have the name, but I wouldn't be surprised to hear major problems from them within 5 years! Nikon's also not doing so well on the Microscope front, whereas Olympus still is!

Sadly I would be too surprised if Samsung takes over the #1 spot. Camera phones are becoming king.

In reply to:

Jorginho: Exciting zoom cam. All is nice and well. But: in these times with 600-1200 mm zooms. Is 24-200 mm still a superzoom? Is this enough for wildlife and birds?

I use the 200-600 mm Panny ion my m43s and can say that 200 mm is surely not enough for wildlife and birds in general. Even 400 mm doesn't cut it.

It is a great cam but what is the usergroup they target? I think that it might be that for most users it is just not "it". Not good enough IQ, not enough zoom, not small enough to consuder over a G6 or a GH3. Not focussing well enough for fast action....

Still: an intuiging cam and for those where it does fit the bill: have fun with it!

Jogger, your nit picking and I think Jorginho's point is valid. For the target market, 200mm focal length is not enough. I can see people buy the panasonic super zoom over this, same size and will not care too much on image quality, just want the image.

Wow, Comparing the Olympus EM1 to the IQ180 is interesting. Setting both to print, you see the slight sharpness difference.

The EM1 only really falls apart with the blue on Red circles. Very interesting.

I think they drank everything on the move to Seattle. This was noticed as the bottle top opened between some reviews.

Your looking at the full res option! Go to the top right and change it to Print or Web to see them on equal footing.

In reply to:

chillgreg: This is a case of shareholder-driven management-driven-accountant-driven-marketing-driven brand dilution. Note the lack of a $500 Rolex or $15,000 BMW.

Ask Coca Cola what happens if you dilute your brand...

It won't bring them down, but apart from a (slight) better balance sheet, it won't be doing Fuji's carefully realised reposition and reputation much good either.

I don't think they are diluting the brand at all. But making it more accessible. Some people don't like the X-trans sensor as still has issues with Raw development. But they like the compact size and the lenses. If this model is popular, you might see traditional Bayer pattern in a better body, like an X-E. Would be nice if you could get an X-Eb (Same body but with bayer sensor instead of X-trans).

In reply to:

Marvol: Is it just me or is this camera just a straight-up head-to-head with the NEX-5 range of models? Nothing more, nothing less? I didn't do an exact count of specs but sensor size, MP, ISO range, kit lens specs, flippy screen, size, design philosophy, Wifi... all say "this is a camera just like the NEX-5".

So Fuji is making this a battle of sensor versus lenses and hope their lenses win?

Fuji lenses do win. But the mistake is no EVF option. NEX-5 does have the option for an expensive but good EVF.

I would have hoped that now with 2 models Fuji would have worked out an external EVF! Maybe in the version 2 of these.

tommy leong: are you able with a quick glance
tell from this Corporate release
how this camera is different from its siblings ???

What art of communication is this...

Yes. I think its easy to tell all the differences.
X-A1, no EVF, Mode dial, Regular Bayer Sensor.
X-M1, no EVF, Mode dial, X-trans sensor.
X-E1, EVF, Classical exposure control, X-trans sensor.
X-pro, EVF/OVF, Classical exposure control, X-trans sensor.

How could you not see that!

A Fool: This makes a lot more sense than a $500 RX100-like lens with no controls that can't shoot RAW.

@Cane, I think your replying to Butoa.

But his is correct the Sony QX lenses seems to be the highest pre-orded camera or what ever it is ever. Stores are having a hard time to get stock.

This think is interesting. Its a single shot, so no Image blur. But the lens is so crazy fisheyed that the IQ seems poor at the distance people (me included) what to look at the image. If they used a larger sensor with more pixels, this might be really good.

On Hands-on with the 20.7MP Sony Xperia Z1 post (81 comments in total)

20Mp is a bit high. But since its on android, would be great for a 3rd party to write a binning software to improve noise. 5Mp would be enough and might offer great results.

Would also be interesting to see if 4K video would be possible. But the process would really have to be fast to handle data. But might be more common now that other 4K phones are out.

In reply to:

nimrod1212: Give either of these a way to power-up externally and an app to remotely connect to something other than a mobile device and I'd buy one or three. The compactness, relatively low price and wireless transmission has numerous applications in wildlife photography, multiple camera video capture, scientific work etc etc.

They have their own batteries and can be used without a phone or tablet. So one of you two is covered. It would be amazing if a 3rd party wrote an Android app to connect to it and offer all the features missing.
