Right around two.5 years when the introduction of Nikon's most up-to-date game-changer (yeah, we're bragging concerning the D3S), its correct successor has emerged. while not qualification, the quantity of hope and expectation surrounding the Nikon D4 was immense. In a way, most Nikonians were (perhaps foolishly) expecting the D4 to be to the D3S what the D3S was to the D3, and we tend to'll confess that we were cautiously saving up precious pennies within the event that the sport was modified over again.


For higher or worse, the particular specifications of the D4 ended up as hardly price writing home concerning, with an ISO vary mirroring that already seen on the D3S, a megapixel rating less than that of the cheaper D800 and a battery rated for fewer snaps than the outgoing D3S. All at an MSRP that is beginning at $800 higher than where the D3S started. you may notice lots of comparisons throughout this text with the most effective Camera of 2009, however that is intentional; yours actually has spent the last two.5 years using the D3S for business and pleasure, and it's solely logical to pit the D4 against a camera that has become molded to several palms here at Engadget HQ. is that the D4 a worthy upgrade? or perhaps a worthy successor? Let's conclude.


Design

Non-technophiles in all probability would not be able to distinguish the D4 from D3S initially blush, and even avid users might have quite a passing look to inform the distinction. whereas there are refined changes all round the body, the D4 remains a monster. In alternative words, those hoping for technology to magically shrink the scale of this issue are going to be sorely disappointed. It's price stating, however, that Nikon has shaved two.1 ounces from the load, that is simply enough to be noticeable the primary time you grab it (coming from somebody who has touched a D3S on a near-daily basis for over 2 years, anyway).


Those at home with the D3S layout can solely need a brief learning amount to grasp the layout on the D4. The Live read button has been ever-so slightly moved, and there is currently a passionate video record button simply north of the most shutter button. Not surprisingly, these are probably owing to the D4's warming to HD video; this guy supports 1080p capturing (20 minute cap in 24p; thirty minute cap in 30p), whereas the D3S stops at 720p (and is restricted to 5 minute clips). we have a tendency to honestly cannot say that the repositioning of buttons on the D4 makes life to any extent further or less beautiful; it's simply... different. we have a tendency to do appreciate the 2 customizable multi-directional nubs on the rear, and we're happy to mention that the infinitely helpful toggle wheels are as solid and sturdy as ever.



The added thumb bumper along rock bottom, that was implanted so as to produce a far better grip when using the D4 vertically, is indeed a helpful additional. Referencing back to the D4's penchant for shooting movies, there is conjointly a awfully welcome microphone input (as well as a built-in mic for amateur captures). maybe the foremost jarring hardware modification is that the built-in Ethernet jack. We've lined the needs of that rather extensively, however it strikes us as one thing which will profit an incredibly touch of shooters. Not that we've a tangle with serving a distinct segment, however we're assuming this is often one issue that added undue price to the package -- one thing we'll address additional in a very bit.
One alternative fascinating modification here is that the deletion of twin CompactFlash slots as seen on the D3S. Instead, users are presented with one CF slot alongside an XQD slot. many years from currently, maybe XQD can appear as if a additional intelligent choice, however it appears super awkward as-is. This move can virtually actually force shooters to currently carry around 2 card readers -- you will assume that is no massive deal, however one additional issue to recollect can virtually actually rub rushed professionals the incorrect manner. it is also not possible to shop for one XQD card over 32GB immediately, whereas SanDisk is hawking a CompactFlash card with 128GB of area. Sure, the transfer rates will hit 125MB / sec (compared to 100MB / sec on the aforementioned SanDisk ExtremePro), however it's still powerful to visualize the logic here. On the intense aspect, a minimum of Nikon did not shove a combine of XQD slots in here and force existing users to burn their CF cards in some variety of dark, hate-filled ritual.


We break this out principally due to simply how fantastic this feature is on Canon's own flagship, the EOS 5D Mark III. Over there, "Silent Shooting" are often used even in high-speed shooting, effectively silencing bursts of shots in an auditorium where you would be ejected if shooting with the everyday, highly audible "click." On the D4, you truly need to move the mode dial beyond High-Speed Low and High-Speed Continuous, over to a passionate "Quiet" mode. Here, you'll solely hearth one shot per shutter press, and every shutter click is delayed quite noticeably. Introducing even an eighth of a second into a nighttime shot will manufacture enough motion blur to ruin the instant, and worse still, this "Quiet" mode is basically something however.


In fact, it's in all probability eighty p.c as audible because the normal click, however it drags on for what looks like forever. the quality click is over and done with instantly; the Quiet click is additional sort of a loud sloshing noise that takes 2 or thrice as long to finally fall silent. beneath no circumstance would we have a tendency to suggest flipping to Quiet mode; you lose valuable shutter speed time, barely gain any noise reduction and develop a click which will probably be even additional noticeable by bystanders just because of how obnoxious the sound is. These days, most folk at a venue will simply tune out a well-recognized sound -- a baby crying, a camera clicking or a gentleman coughing -- however this sloshing sound is not possible to ignore. we have a tendency to hate to mention it, however Canon has Nikon beat six ways in which from Sunday on this one, and it is a shame; there are untold situations where skilled Nikon shooters might use a good quiet mode.


Longing for a better resolution panel over the D3S? Fuhgetaboutit. In fact, prepare for a panel with even worse pixel density. The D4 uses identical quantity of pixels (91,000) within the D3S, however incorporates a show that is zero.2-inches larger (3.2-inches versus three.0-inches on the D3). it's crisp and sharp, however it's hardly an upgrade. we'll confess that zooming into shots up to 46x makes previewing on-the-fly slightly easier, however a rise in megapixel count implies that you will be wishing you had additional dots on the rear of this issue.
ISO 25,600 and beyond
As with the EOS 5D Mark III from Canon and Nikon's own D3S, you'll indeed snap usable pictures at ISO twenty five,600. you will not need to blow 'em up and toss them on a wall, except for internet usage (or simply capturing blur-free reminiscences for yourself or clients), it's a minimum of attainable. something at twelve,800 or below is totally printable, and whereas you will see visible noise on dark shots using ISO eight,000 or on top of, it's remarkably minor within the grand theme of things. Even shots at ISO fifty one,200 might in all probability be used on the net, and shots at ISO 102,400 to 204,800 (Hi 1.0 through four.0) quite literally permit you to capture subjects in near-pitch darkness... handheld.



But here's the thing: this is not nearly as spectacular because it was in late 2009. When the D3S arrived, its nighttime talents were unprecedented within the sub-$6,000 camera market. quick forward 2 and a 0.5 years, and also the D4 makes no major forward leaps when snapping when dark. Yes, autofocus will notice its subject within the dark (perhaps with barely additional accuracy than the D3S), however we'd argue the nighttime capabilities of the D3S are a minimum of ninety eight p.c as stellar as on the D4. the extra quantum leap in nighttime shooting merely is not here. maybe we will be faulted for expecting an excessive amount of, however that is a bullet we'll happily absorb the hunt for consecutive true game-changer.





Fast forward 2 and a 0.5 years, and also the D4 makes no major forward leaps when snapping when dark.
That aside, the results at twenty five,600 and up are simply as wonderful as on the D3S. The shots below were captured entirely at ISO twenty five,600 and up, with no tripod used. It's all handheld, and it's all at nighttime. Also, no post-production (Lightroom, Photoshop, etc.) help was given.

HD video capture

Perhaps the foremost vital capturing update to the D4 compared to the D3S comes on the video facet. there is still no autofocus mode here when viewing video, however the power to capture 1080p24 and 1080p30 with length caps as high as half-hour makes it immediately additional helpful than the D3S. That guy was capped at simply 5 minutes of 720p. what is clear is that -- within the right hands -- the D4 is capable of capturing insanely stunning content. there is practically no jelly result (a drawback that doomed the D90's ability to be taken seriously as a video machine), and therefore the ability to affix your own external microphone can surely tempt skilled still shooters who have continuously questioned what they'd do with a formidable video mode.

That said, we won't very envision too many of us coughing up six giant to use the D4 predominantly as a video rig; if we tend to had to guess, we'd say the worth proposition of paying a grand additional and obtaining twoMark IIIs for multi-angle shooting is much bigger. At any rate, there is a video below cooked up by knowledgeable, followed by a novice clip showing what is created straight out of the camera with none color tweaking or post-processing to talk of.

Image quality and focusing

We'll keep it short and sweet here: the image quality is really outstanding on the D4. however here's the rub: it's simply as outstanding on the D3S and EOS 5D Mark III, each of that are markedly cheaper. the colour replica is simply amazing at ISO levels below eight,000, and even between eight,000 and 12,800, the wash-out that emerges is applaudably minor. like the 5D Mark III reviewed simply weeks ago, we'd additionally trust the D4 to capture even the foremost very important of shots at any ISO beneath twelve,800, that is vastly empowering when shooting dimly lit scenes.
But again, it's here that we tend to'll remind you that we said the precise same issue regarding the (cheaper) D3S some a pair of.5 years ago. We'll let the photographs below speak for themselves, however suffice it to mention, you will be hard-pressed answerable the equipment for any lackluster shots that emerge from the D4.



Nikon's autofocus system is improved, however solely marginally. It's still a 51-point system, and whereas it's capable of finding objects in darker conditions, it still pales compared to Canon's 61-point system on the 1D X and 5D Mark III. That said, it's dead-on correct in use and never left us wanting, but again, the 51-point system on the D3S never did either. (Perhaps you are noticing a trend.)
Battery life
Here's a remarkable one: the battery within the D4 is truly rated to require fewer shots on a full charge than the one within the D3S. You browse that right, however there is a proof waiting within the wings. The EN-EL4 and EL4a utilized in the D3 vary is rated at four,200 shots by CIPA, whereas the EN-EL18 (meant for the D4) is rated by an equivalent entity for two,600 shots. because the story goes, new battery pointers out of Japan forced Nikon to style the EL18 differently, and CIPA estimates shots by firing one shutter, waiting a little and then repeating. Nikon appears to assume that almost all D4 users will not be using their camera in that manner, and if utilized in rapid-fire situations, the EL18 is truly estimated to last longer than the EL4 within the D3 line.

My wife and that i carried each the D4 and D3S to a 10-hour wedding shoot, and each were left within the "On" position for a minimum of ninety p.c of the day. At the shoot's shut, each batteries showed 2 bars of life left, however the D4 solely captured 800 shots whereas the D3S captured nearly one,800. that is real-world results, folks, and it's very disappointing to check a more moderen, costlier Nikon DSLR ship with a battery that truly performs worse than the unit it's replacing. As if that wasn't unfortunate enough, the EL4 and EL4a aren't compatible with the D4, nor the D4's charger. So, users hoping to upgrade to a D4 from a D3 won't be able to use their existing D3 battery in their new camera. Oh, and did we tend to mention that the EL18 is currently priced around $70 quite the (more impressive) EL4a? Bah, humbug.

We wished to adore the D4. In fact, we are able to vividly recall wondering weeks when the D3S' unleash simply what on Earth Nikon would do to one-up it. Turns out, it is not precisely straightforward to revolutionize the photographic world twice in but 3 years. The D4 is just a refined D3S, with a smattering of options that will lure in new customers who disregarded the D3S for one reason or another. Color replica, autofocusing and handling are practically just like the D3S, and whereas the addition of an Ethernet jack, 1080p movie mode and an external microphone jack are appreciated, they will not justify the $5,999 value tag for the majority of consumers.

Even if the EOS 5D Mark III did not exist, we'd still advocate the $5,199 D3S over the D4 for anyone who would not routinely profit of tethered Ethernet action or the 1080p movie mode. When wanting strictly at image quality and nighttime capabilities, there simply are not $800 value of enhancements here. And even for people who are forking out six grand to utilize one among the few actually new options on the D4, you will be doing therefore whereas knowing that your cash very is not shopping for a major upgrade within the low-light performance arena. otherwise of viewing the D4 is this: the D3S is that the D4's worst enemy. Nikon created such a transformational product within the D3S, that the D4 feels additional like one thing that was created to satisfy product cycle needs than one thing designed to blow the doors off of Canon, Olympus, et al. once more.

Nikon D4 tethered Ethernet hands-on
Nikon D4 high-ISO shooting
The other harsh reality here is that the full-frame EOS 5D Mark III will exist, and it's currently selling for $3,499. That's $2,500 but the D4, folks, and therefore the savings you will see by choosing it's quite enough to choose up one or 2 high-end lenses. there is merely no method for many users to justify the large value delta here, and though you are beholden to Nikon because of a considerable lens investment, most everybody wanting to form the leap to full-frame -- hardcore videographers notwithstanding -- are still more contented grabbing a D3S on closeout. you would possibly argue that Canon's 1D X could be a additional smart opponent, and at $6,800, it's definitely nearer in terms of value, however that beast justifies its MSRP with faster burst shooting, additional AF points, a native ISO ceiling of fifty one,200 and a so much, much more versatile HD movie mode.
