spidercrown: sensor's dynamic range may no longer matter in the near future.

The dynamic range of this camera sensor is low, it's just taking multiple exposures to produce HDR images, just like photographers have been doing for years.

dtibi: I'm thinking if the sony A7R2 would handle this scenario or not. But probably not.

Not in video mode, but for stills, sure. As far as I can tell this camera is just doing multiple exposures per frame in order to extend the dynamic range, like photographers haver been doing for years. There's nothing revolutionary going on.

CaMeRa QuEsT: Is the rocket nozzle moving up and down a lot or is it just a terrible case of rolling shutter due to vibration of the camera itself?

I believe it's thrust vectoring of the nozzle, not a camera artifact.

PanoMax: Would be nice if they used a Foveon sensor

@HowAboutRAW

The only way the Quattro competes with medium format is in awkwardness!

The images look good because of the amount of deconvolution sharpening and processing applied by SPP. You can do the same thing to Bayer images with good results...

Nikonandmore: I have the feeling, just about all lenses now are "Leica" and MF price range. Sony, Zeiss, Canon, Nikon.. amazing! I don't understand how these manufactures survive to sell enough of these or how people manage to have money to feed this price frenzy. It will only take cell phone sensors, lenses and technology to get a bit better FOR ONE to buy DSLRs anymore. This market is dead and at these prices, sinking faster and faster. Costs 10 grand (or more) these days to buy a pro/enthusiast grade body and 2 or 3 lenses. Sorry, but this and it's pricing momentum is all becoming absurd. And mind you, these new lenses are all mass produced in 3rd world countries and with more and more dubious quality control. Long gone are the "Made in Japan" days with solid products made with extremely qualified manual labor, excellent quality control AND real long-term post sales support! Indeed Leicas start looking really affordable..

Cell phone sensors will never match DSLRs, there's really not much more room to improve - once you convert 100% of the incoming photons the only thing you can do is capture more photons, which means things have to get bigger.

Lens pricing has gone up, but so too has the quality. In fact the current lenses are arguably better value for money. Look at how much Canon used to ask for their original 35mm f/1.4L. If you don't want to pay these prices, the old lenses are still available for decent prices.

And finally there's no evidence quality control was any better in the good ol' days, I'd guess variance was just as high but no-one knew about it because film was too expensive to waste on shooting test charts and brick walls!

"The Tamron 85mm F1.8 claims the title of the world's first fast-aperture 85mm lens with stabilization"

Zeiss Batis 85mm f/1.8 anyone?

TyphoonTW: 70-300mm F4.5 – 5.6 = $1,200
Is Sony slowly trying to compete with Leica?

@TyphoonTW:

"Why are we comparing this to Canon's L lens? Just because it has the letter G ?"

Yes.

shigzeo: In contrast to anachronistic cameras from Fujifilm, Olympus, and even Nikon, this is refreshingly forward-looking. And unlike Sony, it isn't festooned with badges. Is it pretty? I'm not sure, but it is attractive. Well done.

I assumed by "badges" you meant features, because looking at my A7R there are only 2 badges on it which hardly seems excessive... as for the number icons, I turned those off as soon as I got the camera....

Thematic: Fantastic releases.

Depending on where the prices settle, these models with a nice ART series lens should make for a compelling combo.

Macro, comercial, still life, landscape, travel, portrait, documentary, fine art etc.

Exciting!

You mean... macro (in really good light/studio), commercial (in a studio), still life (with a tripod), landscape (in good light), travel (in good light), portrait (in a studio), documentary (in really good light), fine art (in good light).

Horshack: For those unfamiliar with what the Foveon is capable of, here is a full-sized sample from my DP2M. The shooting envelop is rather narrow in terms of color temperature and ISO but as a portable landscape camera it's extremely impressive.

https://horshack.smugmug.com/photos/i-4ddV9hG/0/O/i-4ddV9hG.jpg

There's a LOT of processing going in in DPP (the results from Sigma cameras with Irident Developer don't look anywhere near as good). If you replicate this processing you can get the same level of detail and "pop" with a high-res non-foveon sensor, but you'll also be able to take photos in low light!

> unlike Sony, it isn't festooned with badges

Yes, thank God they didn't put a full frame sensor or image stabilisation in there!

On article Primer: Why would I buy a mirrorless camera? (563 comments in total)
In reply to:

KrisAK: My Canon AE-1 35mm SLR has a massive optical viewfinder...the biggest I've ever used. And yet, dimensionally, it's only a few millimeters wider than an A7 series camera, and actually a bit thinner. With a 28mm FD lens, it's remarkably portable.

At what point in digital camera history did FF DSLRs feel the need to bloat into their current form?

Why can't there be a digital AE-1?

There's a heck of a lot more in a DSLR than a film SLR, circuit boards, batteries, large AF units, LCD screen, card slots, USB/hdmi ports. All that stuff has to go somewhere. Look at a teardown of a DSLR, it isn't just empty space in there (well except for the mirrorbox).

Clyde Thomas: Love these specialty efforts. In a day when some manufacturers are pulling out of entire markets because of downward predictions, Pentax/Leica move ahead with specialty/luxury gear for extremely limited markets.

I mean, did Pentax conduct a trend report concluding that MF IR cams were going to be the next big seller? Kudos to Pentax for making photographers their first priority. This is great news for our industry and strengthens my entire perception of Pentax all around.

"I mean, did Pentax conduct a trend report concluding that MF IR cams were going to be the next big seller?"

Yes I imagine Pentax did some research into use of MF for scientific and conservation purposes that revealed there is a small demand for MF cameras that can shoot in the IR spectrum, at a price that covers the additional cost associated with manufacturing these camera. It's called business.

armandino: I knew this one was going to be trouble. It is virtually impossible pic one camera out of the bunch without a clear mandate of what you are looking for. These cameras are so wildly different that are pretty impossible to compare. Even the price range is so broad. I think It should have been more of what to recommend each of them for.
Personally I do have an A7RII and for as much as I love it and it is amazing what you can do with it, it could not possibly be my only body because just not reliable enough. I am sure that of enthusiasts it is perfectly fine, but for a pro some of its glitches are just infuriating and at times cause of missing the critical shot.

"It is virtually impossible pic one camera out of the bunch without a clear mandate of what you are looking for."

That's why you have to take the award for what it is and not get too upset about it. DPReview aren't saying this is the best camera in absolutely every area, they're just giving out a awards to cameras they think are the best overall. It's just like many other such awards, Time magazine's man of the year for example. Of course it's subjective.

Zeisschen: You know your company has done a tremendous job when you read so many butthurt comments on dpreview section...

Kudos to Sony for being the biggest and most constant challenger and innovator in the camera market since 5 years! The camera world would be boring without you!

If by "ignored" you mean "issued a firmware release to fix", then yeah.

forpetessake: Sony might have made the most technical advances. But in the end of the day it's the pictures that matter. And honestly looking at all those samples it's hard to deny the two Canons the most pleasing colors and tonality, far better than Sony.

Lets see do I want warmer colours out of camera which can be achieved in Lightroom in 2 seconds, or two stops of dynamic range that absolutely can't be replicated in post... tough one.

In reply to:

Felix E Klee: Couldn't this tech be used to get shallow DOF with a smartphone?

Actually you could use this to build a depth map using DFD and then compute a simulated lens blur using that, allowing an arbitrarily shallow depth of field (with any lens with shallow enough DOF to build an accurate depth map).

On article Panasonic's Post Focus feature arrives November 25 (218 comments in total)
In reply to:

GaryJP: So "post focus" basically means taking a still frame from a video focus pull.

It's more that just that, the software analyses each video frame to automatically detect the in-focus areas so you can select a point and it will give you the frame with that point in focus.

On article Panasonic's Post Focus feature arrives November 25 (218 comments in total)
In reply to:

bernardly: There are 2 possibilities. This post-focus technology might be synthetic computational in nature. However, Panasonic cameras are conventional in that the lens focuses the image on the sensor plane at one focal distance at a given time of exposure and records only the intensity and not the direction of the light. If so it might be an interesting gimmick but not much more than that. The other and more likely possibilty is that the camera racks focus at 30 fps but that would not necessarily capture the desired moment. I would prefer the 2nd possibilty and I admit it would be an attractive consumer feature but the tradeoff is giving up the full resolution of the sensor. Another question is would the feature be available in RAW mode? That is 30 fps 4K RAW shooting.

There is one possibility - the article explains quite clearly exactly how the new feature works (did you even read it?): the camera records a 4K video whilst racking focus. It then analyses the images to detect what is and isn't in focus so you can select a point and it will figure out which video frame had that point in focus.

On article Nikon announces development of flagship D5 DSLR (442 comments in total)

First there was the D1, then the D2. After that came the D3. In 2012 they gave us the D4. And now we hear they are working on a D5. I'm definitely seeing a pattern here!
