On High-end full frame roundup (2014) article (573 comments in total)
In reply to:

StephenL: When will people realise there is no such thing as full frame? m4/3 is full frame to an Olympus user. Yet to a Pentax 645 owner, a Canon 5D sensor is tiny.

"Full frame" is NOT 35mm. 35mm actually refers to the film gauge popularized by movies (which were then shot 4-sprockets/frame). My understanding is that the use in still cameras began for testing exposure and processing, and then took off as a way of leveraging movie film for stills. A variety of movie film formats, including ones that specify anamorphic compression, are still based on 35mm film.

What still photographers now call full frame is the 36x24mm, 8-sprocket/frame, use of 35mm film in 135 cartridges. So-called half frame 135, at 4-sprockets/frame, was also reasonably common and roughly matches APS-C -- but it is essentially the originally intended 35mm movie frame size. Thus, one could argue 36x24 is actually double-frame 35mm. ;-)

Odd that people get so upset about a name. Also interesting that the most popular still formats today come from a fusion of movie and still technologies that happened a century ago....

Let's see... pick a body using a Sony sensor. I don't necessarily agree on the details, but that sounds right to me. Canon really needs to get it's act together.

It's done... and the top 3 are all kite photos!

Obviously, KAP is alive and well in the drone age. :-)

On Kalari Fighters in the Up in the air challenge (6 comments in total)

As challenge host, I don't get to vote... but I'm very happy to see a shot like this. It's really impressive -- and even moreso taken from a kite. I suppose it could have been luck, but I think it's much more likely that the photographer deserves credit for recognizing the potential shot and making it happen at the extreme effort of using a kite rig (and at the water's edge, which adds a little to the equipment risk and constrains the kite control).

On Samsung NX mini Review preview (105 comments in total)

The high-ISO raws looks really impressive. I'd guess Samsung is doing significant cooking of their raws, but it's hard to argue with the results. Samsung is doing a great job on the JPEG processing too. Not a camera that appeals to me, but it's worth noting that Samsung is doing a heck of a lot right on everything in cameras right now....

On Enthusiast mirrorless camera roundup (2014) article (304 comments in total)
In reply to:

cxsparc: Very weird, where do I find the A6000? Given its performance is better than the Nikon 1 and at least on par if not better than the M1, and also that for the next part the A7 is supposed to be included, this selection is very odd.

Yeah, as many have pointed-out, DPReview seems to have bent over backward to leave out the Sonys that actually dominate this market sector. I get the feeling they wanted the GH4 to win something... and perhaps it should, but what it should win is something more like best self-contained 4K capable (although I'd probably give that to the NX1, a slighting which I guess DPReview compensated for by doing that "fluffy" video "review").

On Enthusiast compact camera roundup (2014) article (185 comments in total)

I think all these comparison articles narrow the field too arbitrarily, but do have some useful content within the group they review. Favoring the LX100 seems to have worked in that it's the one listed as "out of stock" at the end of the article. ;-)

Actually, the $120-more-expensive black version LX100 is in stock; it's just the silver version that isn't. Strange price difference....

In reply to:

hindesite: I'm very surprised by this - if you read the popular sites, it seems like everybody is using quadcopters and KAP rarely gets a mention, but here the kite photos far outnumber the others. They are also pretty good quality - for something that for me resembles "fishing" for photos :-)

I wonder if kite photography is really more popular, or are the quadcopter pilots spending all their time learning to fly and repairing instead of taking photos? :-)

I suspect we're seeing three things here:

1. KAP has been around for a lot longer than quadcopters.

2. KAP is hard, and the people who do it are very serious about it. The KAP community is filled with people who have great technical skill and have invested lots of time in developing their KAP skills.

3. Kites can lift heavier camera rigs, and go higher, than most cheap quadcopters. The KAP cameras often have better IQ than the cheap, light, ultrawides typically on quadcopters.

For what it's worth, I have an ARDrone 2.0, and the built-in cameras do quite well in the same way the GoPros do well: nice video, somewhat unimpressive stills. I wasn't good enough (ok, maybe I just didn't put enough time in?) to get much going with KAP, but you definitely can get better IQ.

I'm very impressed with the kite (KAP) photos. I expected most entries to be from quadcopters, but that obviously isn't the case. Interesting.

Well, mounted to your head the camera is automatically or remotely triggered, so it fits the rules....

By now, everyone who would consider buying one of these knows what they're getting -- a nice Sony camera wrapped as a collectible conversation piece. It's for people with too much money to show their friends.

On Evening Colors from the top of the Aruba Hyatt in the Up in the air challenge (2 comments in total)

This is a close call for the rules. If you shot it using the self timer or remote trigger, rather than holding the camera, it would technically meet the rules for this challenge....

hindesite: Unbelievable. Can people not read the challenge description? The camera is supposed to be in the air, not (necessarily) the subject.

50% of the entries do not meet the challenge rules, which are quite clear.

Those would no doubt be photos taken holding the camera in one hand while tossing the cat in the air with the other. If only they would toss the camera and hold the cat, the photos might qualify. Oh well. ;-)

Shocking, isn't it? I just disqualified 'em.

THE QUESTION is: does this 5-axis sensor movement work with UNCHIPPED manual lenses? For their A-mount bodies, the answer is very foolishly no. I hope that Sony has not forgotten to put menu options in that allow users to specify the focal length of the lens so the IBIS can do its job without requiring a chipped adapter. This is absolutely critical!

CameraLabTester: Hands up, those who will use this!

Come on!

Don't be shy!

Anybody?

Okay... A D750 or 5DIII to anyone who will buy this!

Anybody?

Anybody? (echo)

.

Well, I might... and if you'll make that a Sony A7S/A7/A7R instead of a D750 or 5DIII, I'm sold!

Honestly, it seems to be a fairly well thought-out 360-degree/stereo arrangement using compact camera class components. The physical design is quirky, but clever (and their 3D-printed prototype doesn't look too different from things I've 3D-printed to hold Canon PowerShots in my research). The problem is that this is a very niche product, and most people wanting the "systems camera" features will also be wanting really top IQ. If this was built using four copies of the Sony sensor from the A7S, it would be amazing, but it seems more likely it is just yet another quirky multi-compact-camera thing.

The biggest issue I see with the design is that the lens tubes are a bit far apart for 360 capture. The rule is closest object should be about 30X the distance of the offset from a perfect lens position, which I'd estimate in this case means around 8 feet.

Probably will not be funded....

Very nice research project. Actually, quite simple technology... could easily turn into a modestly-priced product. There will be some stitching issues, which I guess is why they're talking about "3D-aware stitching," but it probably will be pretty good as long as nothing is too close to the cameras....

On Samsung NX1 real-world sample images article (330 comments in total)

Samsung already owns much of the camera market via cell phones. It's obvious from the specs that Samsung also is trying to be a leader in serious system cameras, and the sample images show that they haven't screwed-up very much. I look forward to a teardown, which I expect will reveal that this is almost entirely made from Samsung parts and subsystems. In the near future, how will other camera companies compete against the targeted resources of arguably the world's largest tech company?

Here's hoping this is a motivating challenge to companies like Canon, and not the big, bright, thing in the sky that causes a mass extinction when it hits.

In reply to:

ProfHankD: Not relevant to digital photography and hence not to DPReview. Yet another company trying to distinguish itself by echoing a past that never really was. The irony here is that Land and Polaroid were all about developing new technologies, from instant film to sonar sensors for autofocus. This is just sad.

Looking at the web site, I don't see this targeting artists -- although there has been a lot of art done on Polaroid film using pinholes. I've done a heck of a lot of photographic experimentation, but to me this feels more like mediocrity masquerading as an exclusive nostalgic experience.

It really bothers me to see people being encouraged to waste their money in this sort of way, and the association of it with such an innovator as Land adds significant insult to the injury. Look at their web site to fully appreciate just how heavily they are milking Land's good name (and no, this camera isn't anything like the model 95).

In the end, I suppose it's nothing more than very aggressive marketing of a decent pinhole camera that takes the now rather expensive film they make. And they do deserve credit for saving Land's film technology.... SIgh. I still think this is very sad.
