wetsleet: How come they don't just make the thing waterproof right off the bat, instead of faffing about with a separate rain-jacket?
And can we have it in a heat reflecting colour please? In a hot sunny country your gear fries in a black bag.

it's pretty grim out there! The camera bag market generally, I've never been too impressed. Lots of same-old products relaunched to get the column inches. Very much like inkjet printers, just the same menu served up again and again with a new model number.

The challenge has been met, except by Lowepro. Waterproof jackets these days, they have waterproof zips.

arrr: Very nice but is this just a HD version of a FRESNEL LENS?

no. A fresnel lens is a refractive glass lens, same as a normal lens, just folded in on itself in concentric rings like a bellows.

LukeDuciel: As an illiterate in optics, my 1st reaction is "renamed Fresnel lens?"

But I feel this might be the break through we have all been waited for. We know from high school physics: when the dimension of things are reduced to be comparable to the wavelength of light, a lot of strange stuff start to happen.

A Fresnel lens is just a regular refractive lens concertinaed down. It has the same refractive curved surface of a normal lens, collapsed down in a series of concentric rings, so that the interior bulk of the lens is removed. The easiest example to understand is old lighthouse lenses, where you can clearly see what is going on.
Whatever these guys are doing, it is not normal refractive optics.

taktak91: Another spectacular product from Nikon that is incapable of replacing my D300, nor my K-5 II, which I ended up purchasing.
Is Nikon suggesting that I should eventually replace my K-5 II with K-3?
That's fine by me, but I don't know how Nikon can profit from it.

fair enough

Aur: I'll never undererstand the argument some ppl use about weather sealing. Afaik, none of the DX lenses have weather sealing, only FX lenses have it. Are people really putting $2000 lenses on a crop sensor?

If you want weather sealing, you should be looking at Pentax, they have $200-$1000 lenses with weather sealing. Nikon only has weather sealing in their most expensive lenses, and even on those, Nikon seems very reluctant to tell users how much they can withstand, the info is really hard to find. Pentax has no problem telling it's users which lenses are fully weather proof and they even show it off in promotional videos.

Ppl take these cameras on safaris and then complain about dust on their pictures with Nikons, yes..because none of the DX lenses are weather sealed, so your body being weather sealed is completely irrelevant.

I'd love to know where you get info *from Nikon* about weather sealing on lenses. I've looked, they just don't mention it. Maybe I missed it?

"you probably favor the Pentax or you need the extra reach a crop camera gives you."
Um, that "extra reach" through cropping is equally available on FF bodies. In fact, I'm not sure why all the D400 die-hards don't just get a D750 [pro build quality, layout, features, image (no, that can't be it?)] and stick their stable of DX lenses on it.
After all, the D750 weighs less than the D300, and is near enough the identical size. What's to gripe about?

tonywong: Not ripping into Mr. Burrard-Lucas but I guess everyone will want their share of the drone photos before it gets commonplace and/or regulated. Since he spent a year in the area he likely exercised due diligence and caution regarding the welfare of his subjects but other photographers may not.

I am conflicted about the use of drone photography in wildlife photos. In the crush to get the closest and newest photos and perspectives that no one else has gotten yet, will the animals now be surrounded by a cloud of flying drones and wheeled remote buggies during an animal encounter?

It is bad enough to see multiple rows of jeeps surrounding a lion hunt in eastern Africa, but now everyone will have to contend with photoshopping out the remote cameras popping in and out of their photos.

I think that there may have to be a policy once these devices become commonplace and common courtesy is forgotten, and the animals will be constantly harassed by these devices.

"It is bad enough to see multiple rows of jeeps surrounding a lion hunt in eastern Africa"

It's not pretty, but it keeps the lions alive.

otto k: Regarding multiple shots without tripod: apparently samsung is able to read full 28MP sensor in NX1 240 times a second. It might be DR limited, we don't know yet, but if sensors are able to complete full scan in 1/1000s in few years time it would make multishot usable without tripod. For 8 exposures one would need to hold still for 1/125s which is quite manageable even on tele lens with OIS already. It could also bring CMOS sensors closer to dropping mechanical shutter altogether.

otto, I was asking is it possible smultaneously to engage OIS and 40MP mode? The sensor shift would have to add together the movements required for both functions. So at the same time as executing its 8-point circuit to achieve the 40MP image, the sensor would need to overlay the compensatory movements required for OIS. It might be possible but it is far from self-evident, and the issue is not addressed in the article.

Will it be possible to combine in-body OIS and simultaneously execute this sensor shift pixel multiplier?

Cane: Are companies just going to keep churning out the same small sensor in this genre? Either you suffer marginal image quality or you buy an big and expensive case for a good camera. The in between is a vast wasteland.

They did, they called it the Nikon 1 AW1

Since the zoom lens has to be constrained within the camera housing, I guess that imposes limits on the size of lens, hence on the size of sensor.
Maybe a bigger lens housing protrusion would be acceptable?

sybersitizen: This new version appears to do its intended work very well, but...

Why does the program, like so many new Windows programs, have to LOOK like a Tinkertoy app running on a Windows phone? There's not a hint of the visual richness and dimensionality that Windows 7 on a REAL COMPUTER so easily provides. All we get is a dreary, gray, flat rectangle. Who declared total lack of esthetics (AKA the Win 8 experience) to be a good thing? Even the Start Menu icon is dull.

Why am I not presented with a drag-and-drop interface until AFTER I load up at least one file from the Windows Explorer interface? What's the point of that?

Why do we have to look at advertisements and panos made by other people every time the program is started?

These things might seem trivial on one level, but they truly diminish the value of what ought to be a visual showcase and something that's fun to use. Despite the functional enhancements, I'm actually considering going back to version 1.4.4.

+1 on the flat thing. I will never understand why flat and featureless Metro/Material design is now preferred over a richer 3D UI. So little for the eye to hang on to. Usually compounded by light grey 10-point text on an eye-watering expanse of shimmering white background (except DPR :) )

viking79: Looks like they are going for possible 645D and other medium format audience.

Nice cameras, sensor/processor upgrade to 5DIII? Too bad about the price, a 50 MP sensor doesn't really cost any more to make than a 20 MP sensor. I suppose they can justify it being the highest resolution, but I never thought MP alone should up the price of a product.

Sony did this with the A7R and A7S as well, ask dramatically more for the same camera because of different sensor. They did a good job of modeling Canon's business plan :)

since when did cost of production affect sale price? Only in the UK's Ministry of Defence procurement. But not in a free market.

In reply to:

theprehistorian: @Rishi - did you check to see if the flare banding was any different after fine tuning the AF? Presumably the adjustment had the effect of lowering the AF module...

"Presumably the adjustment had the effect of lowering the AF module.."
I would assume the AF fine-tune adjustment is a programmable offset in the focussing algorithms, not a physical offset of the AF module.
Edit - I see Rishi types faster than me!

ealvarez: I just tried multiple number of entries of serial numbers and found

equal or greater than 8802634 are not affected

equal or greater than 3026254 are unaffected

I found Serial number beginning with 8XXXXXX are for cameras that being sold in asia and 3XXXXXX for USA and maybe Europe. I'm just guessing but

Try for yourself

is there supposed to be an "equal to or less than" in there somewhere?

On Real-world samples: Sony Alpha 7 II in Kauai article (227 comments in total)
In reply to:

neo_nights: Let's face it: sensor technology has got to a point where you simply CAN'T decide between cameras based on image quality alone. Unless you pixel peep (which is expected from a gear forum, I know), a picture *well taken* with a Canon 1000D and a Sony A7 is negligible for most people's eyes.

So, while those galleries (by 'galleries' I mean: from all the recent cameras that have been posted on DPR) are nice to give SOME idea about a camera, it can't be the decisive factor.

Too true. The first thing I look for is the size of the viewfinder. Then comes handling and ease/accuracy of focus.

Sammy Yousef: "Better" or "just as good" depend entirely on what you're shooting. Under the right conditions and in the right presentation media the phone will do nicely next to a much more expensive DSLR. If you're buying a DSLR purely to take medium wide angle photos in bright even light only to post them on social media then you may well be wasting your time.

This accessibility is fantastic. It allows people to play with framing and composition without an additional financial outlay. It means where 10 years ago you'd normally be caught out because you didn't have your camera with you, you MIGHT just have something suitable sitting in your pocket to capture that shot.

If that moment you're capturing involves long zoom action sports, wildlife, astrophotography, architecture, extreme low light etc. your phone won't cut it and your current DSLR might not be enough. You might be able to capture something complimentary that would suit your phone. (Crowd watching sports for example).

""Better" or "just as good" depend entirely on what you're shooting."
Agreed. Often, in close quarter social situations, whereas taking pictures on a mobile is just part of the scene and unremarkable for that, brandishing a DSLR marks you out as "a photographer" (or even "the" photographer), and changes the scene you are trying to capture.
