On Hasselblad unveils pixel-shifting 200MP H5D-200c MS article (248 comments in total)

I'm rather surprised that no-one has mentioned the "Photoacute" software package that does essentially the same thing with a series of files taken by any digital camera. Their trick works and the package is not very expensive. Processing is a bit slow - and requires more than 4 images for best results. You can try it without having to buy the package - but the images cannot be saved without a disfiguring watermark.
What matters most are the quality of the lens, accuracy of focus and having a static subject. Since there is no point in trying to make super-resolution images when any of these factors is lacking having the option built into the camera at enormous extra expense doesn't really make a lot of sense. Since a basic 16-25Mp image is more than sufficient at almost all ordinary print sizes the need for such acuity doesn't arise very often.

In reply to:

oldfogey: Either I'm blind or DPR has missed the most significant advance that this camera represents. The high ISO RAW files from the FZ-1000 are almost as good as the best m4/3 cameras, are significantly better than those of the Sony RX-10 and are dramatically better than those of the Nikon V3. If this really is the same 1" sensor that Sony put into the RX-10, Panasonic know something about signal processing that Sony/Nikon did not.
DPR's also claims that the Sony lens is sharper than the Panasonic's. If so the test images shot with the Sony must be a bit out of focus.

Look at the portrait of the bearded gentleman. Chroma Noise destroys all detail in the V3 image whereas there is very low chroma noise in the FZ1000 image. Although chroma noise is relatively easy to reduce there is always a loss of detail. There is still significant hair texture any eye detail in the FZ1000 image. The Sony is somewhere in between.

In reply to:

oldfogey: So DPR - apart from the lens comparison and RAW image dynamic range questions frequently noted below.- How much video 4K or 1080P can the FZ1000 record on a single battery charge? Does the sensor overheat when long video clips are recorded? What are the filesizes/min? And How well does the IS system work?
By the way how can any lens based IS system do "5 axis" - i.e. (especially) correct roll? And what about flash - is the wireless control the same as Olympus's or would one have to invest in a different system?

jkoch2 has the "Right Attitude" while "Prince-cody" is clearly a fanboy. If you have ever been stuck having to change batteries while trying to record a presentation with the camera on a tripod you would know what a serious issue battery life can become. Unfortunately manufacturers don't often provide this sort of information although it can be vital - and the "try it for yourself" approach really would make the effort spent reading reviews pointless. My question about "roll" correction is one that doesn't seem to have come up in discussions of image stabilization - but it is one area in which IBIS systems may have a definite advantage over optical stabilization.

Reply to Quapat below. I was looking at the ISO 12800 comparison where the FZ1000 does seem to hold the edge. Funny how the results seem to vary over a 1 stop window.

peevee1: DPR wrote: "The first thing you'll notice here is that a) the Cyber-shot DSC-RX10 is noticeably sharper"

Huh? Check out the brick building near the bottom right corner, and a yellow structure near it. There is no question about which one is sharper - of course it is Panasonic. There is not difference in the center, but FZ1000 clearly wins in the corners, at least at wide end.

Also check the foliage - the Panasonic is much better in the off central areas of the 25mm image, the Sony 24 mm is a fuzzy mess.

On Budget M43: Kodak Pixpro S-1 First Impressions Review article (137 comments in total)
In reply to:

Mike FL: Per DPR, S1 has "...extensive use of plastics in their construction, including the mounts...".

Metal body but plastic mounts. now we know why Kodak went out of the business yeas ago...

The 40-150 m.Zuiko is sold as part of a 2 lens kits with the e-pm2 and e-pl5. My copy of this lens is significantly sharper than my copy of the Panasonic 40-150 f4-5.6 - or either of my Zuiko 40-150 4/3 lenses. In my experience of 4/3 lenses with plastic parts there have been no issues that relate to the use of plastics. My only concern would be that after many-many lens changes the flanges might wear slightly so that the lenses would not sit as tightly in the bayonet but thus far it has not happened. Obviously they might not survive a severe sideways blow as well as a metal flange - but I would rather have the lens break off the camera than have the whole camera destroyed.

On pool_fun in the Those Lazy-Hazy-Crazy Days Of Summer challenge (15 comments in total)

A delightful image - but appalling Image Quality. This is a Photo site, not facebook! I really think it should have been DQ'd on the quality issue alone - if it really was taken with a Nikonos and not a phone in a plastic bag the scanning could have been done at higher quality.

Few Mac owners realize just how conveniently their bundled iPhoto program handles RAW files. Providing you have a supported camera, RAW files are developed automatically when the file is imported into iPhoto - and are redeveloped when adjusted with the iPhoto editing tools - so that the current JPEG or TIFF does not deteriorate through rounds of adjustment. The convenience of iPhoto's in-line RAW conversion has turned me into a RAW-only photographer - which makes all of the fuss and bother about comparing cameras' in-camera JPEGS on this site and others - a waste of time.

rsf3127: Minolta Rokkor 58mm f/1.4 @ Ebay: 49 usd.
Adapter: 10 usd
Rokkor on my NEX: priceless.

Have you checked its transmission? I bought a 50 mm Rokkor X PG hoping that it would be a stop brighter than my ZD f2 macro. It was only about 1/3 of a stop brighter, and although very sharp for an f1.4 of its generation, nowhere near as sharp wide open as the ZD. It does have a shallower DOF wide open so I have kept it, but mostly these days I use the equally bright and much sharper mZD 45mm f1.8 -which also auto focuses very quickly. At 90mm/f2.5 equivalent FOV/DOF to the Nikon not a strict replacement for a 58 mm ff - but less than 1/3 the cost.

babalu: I think I'll revise my opinion about vote rigging.
I have now looked again at all the entries, and, just from an aesthetic point of view, this is a worthy winner. I concur with Rumpelhund's comment below.
Congratulations .
(still, the voting seems to have a strange pattern; 11 5.0 votes are very rare).

Voting pattern in Langenheinrich's 34'th place entry in I Spy: women with red clothes (Nov 10, 2012 ) look similarly anomalous - maybe that time not quite enough high end 5.0's to bring it to the top.

thomo: I can't believe mine came 129th - and they were real photographers!

Accept it as a badge of honour! Perhaps a better way to judge your acceptance is to count the number of "views" that show up in your gallery before the voting is finished. Even though I came in 40'th that image received 56 views before the voting was completed - and I didn't think it a "good photograph" - although it did show a subtle interaction between two budding female photographers.

Regression to the median! One of the problems of challenges that also allow the entrants to vote is that the winner is most often the median of the entries. She does look cute - in a sexist sort of way - but hey - wasn't that how most of the entrants interpreted the challenge. This wasn't an effort at gender equality after all! The focal plane seems to be on the stockings rather than on the eye makeup.

On Panasonic Lumix DMC-GX7 Review preview (566 comments in total)
In reply to:

oldfogey: An undocumented but very useful feature of my old EPL-1 was the on body flash that can be tilted into a vertical (bounce) orientation with a little pressure from a forefinger. Unfortunately that capability disappeared from later editions of Oly cameras - so the "deer in the headlights" direct flash option is the only choice with Oly's newer m4/3 bundled flash units. It looks a little as though the Panasonic GX7 unit might be able to do the EPL-1 bounce flash trick. Could DPR or any of you GX7 owners out there comment on this?

No it isn't useless - in a small room with a white ceiling the EPL-1 flash in bounce mode is a very effective assist. You're forgetting that the sensitivity of modern digital cameras allow good signal to noise at high ISO and that some of the fast lenses available for m4/3 can give a usable image in typical ambient artificial light without any flash assist. And don't go telling me that I should be using a full frame. I do own a powerful add-on flash - but these days I almost never use it.
