"The full-frame DSLR market is highly competitive with solid options from several manufacturers including Nikon, Canon and Sony. And while Canon has had a grasp on those shooting DSLR video since the introduction of the 5D Mark II, Nikon has definitely moved forward with the D4's video features.
But this powerhouse of a camera isn't just for shooting video. Exceptional still images, a feature set that is far too long . . . read more
"Not trying to make any point here, I just love cameras and also statistics. So, I copy, pasted, sorted and tallied the data from the "Reuters Full Focus - Best photos of the year 2012" page (look for the link and thread at the top of  http://www.reddit.com/r/photography/) I'm an amateur and I like to absorb what I can from shot data. Here's what I tallied: Camera: Canon 1D Mark III (4), Canon 1D Mark IV (26), Canon 1D X (6), Canon 5D (3), Canon 5D Mark II (19), Canon 5D Mark III (8), Nikon D3, NIKON D3S, Nikon D4, Nikon D7000, Nikon D800, Sony DSC H5, Prime Lenses: 15mm, 16 . . . read more
"This full-frame DSLR is built for professionals with a sturdy weather-sealed body that provides a large number of accessible controls including dual control-dials and an 8-way joystick on each of its two grips. The Nikon D4 has most features ever built into a full-frame DSLR save for a built-in flash. It adds plenty of its own include an FTP client, built-in HTTP server and Time-Lapse Video."
"At the 2012 Games, Marit and colleague Antonin Thuillier will set up a dozen robots: 10 on the roofs – including one above the Olympic Stadium – and two in the swimming complex. Among the robots deployed for aerial shots, two will have a double camera enabling wide-angle panoramic shots. With 16-to-400 mm zooms, and three axes of rotation, no angle will escape the cameras’ Cyclopes vision."
As has been widely reported lately, Nikons new full-frame cameras, especially the D800 appear to be laden with a number of bugs/malfunctions, that include random lockups and viewfinder/focusing alignment issues. Fstoppers writes about the out of alignement viewfinder issue, and PDN news covers the lockup bug together with Nikon's response and the temp-fix on hand.
"Like its forebears, the Nikon D4 is an extremely well built and responsive camera that seems to react instantly to anything you throw at it. Start-up feels instantaneous, there is no shutter lag to speak of and with the right lens mounted, focusing is also very fast. The camera is about as rugged as it gets, and the ergonomics is first class. There is a multitude of ways to check and modify . . . read more
When it comes to Engadget the 'field' is a bit all over the place:
"We wanted to adore the D4. In fact, we can vividly recall wondering weeks after the D3S' release just what on Earth Nikon would do to one-up it. Turns out, it's not exactly easy to revolutionize the photographic world twice in less than three years. The D4 is simply a refined . . . read more
Yes, we're way past the 'it goes to 11' moniker. The British bookies should start a new bet: 'When will cameras reach 7-figure iso numbers'? My money is on year 2016 (Don't ask why). Anyway, the D4 does wonders, doing a quick oogling and peeping, i think it's safe to say it tops the D3 in every aspect, at least in the series of photos provided at Imaging Resource. . . . read more
Not very much to see here, but a little bit of more info on the D4 is better than no info at all. Oh, and Engadget needs to send some of its editors to video school asap :)
"Support for RAW images captured with the D4 has been added.
"The first High ISO test of Nikon D4 with D3 published at mgphotographer, Before you jump to any decision please note that the D4 used in the comparison is loaded with a BETA firmware, so final firmware version of Nikon D4 may have some better performance, the images taken with the . . . read more
"Usually when something big in tech or photography happens my friends start asking me "did you order one?" This time the big news is the newly announced Nikon D4 DSLR camera. Let me start by saying that I've always had Nikon D3 envy, but just couldn't justify the price. I don't need the . . . read more
"The downsampling of the sensor is similar to the Nikon J1, a $499 mirrorless camera. According to Nikon, “subsampling is only along each horizontal video line; there’s no sub-sampling between video lines. ” Frankly this is bloody ridiculous. I’ve seen the results of this on the J1 and it . . . read more
"The camera is amazing. The high ISO files exceeded my expectations, and after the D3S I had huge expectations! The new video and audio functions have transformed this camera into something beyond what we have seen before. . . . read more
Interesting read for a D3s owner:
"There are things I really like about what Nikon did with the D4 back layout/design and things I don’t. Let’s start from what I believe are good changes. Compared to the D3s, there is one extra button on the back of the D4. Finally, Nikon adapted . . . read more
"As a still photography camera the D4 is a much more modest advance over its predecessor. Announced in October 2009, the D3s had a resolution of 12.1 megapixels while the new D4 comes in at 16.2 megapixels. Not bad, but also nothing like the 20 MP some had been hoping for. The Cannon EOS 1Dx has an effective 18.1 megapixel sensor. . . . read more
"For a professional camera, however, the D4 is inviting and sophisticated, with minor tweaks to an established design. The control layout is nearly identical when shooting in either portrait or landscape orientation, with familiar access to the control joystick, top and thumb control dials, shutter . . . read more
"The PowerShot G1 X handles much like the PowerShot G12. However, its fixed 28-112mm (equivalent) zoom and fully-articulated rear LCD are coupled with a sensor only slightly smaller than that used in Canon's APS-C format EOS DSLRs. [...] " . . . read more
"For example, the D4 is the first digital SLR from any maker to incorporate a headphone jack for audio monitoring while capturing video, plus it can export uncompressed 1080p video through the HDMI port to an external recorder. It's also the first Nikon digital SLR to incorporate on-board wired networking, in the . . . read more
Via Photography Blog:
"Shot exclusively with the D4, incorporating both stills and video, and featuring a mountain biker, climber and kayaker, the Nikon D4 release video is a mouth-watering showcase of just some of the things that this flagship DSLR is capable of."
Check out our extensive hands-on 38 photos gallery of the new Nikon D4 camera at photography blog.
"The biggest change is, of course, the improvement in video capabilities. Given the increasing demand for video footage from professional photographers, and the incredible success of Canon’s 5D Mark II in the professional video market, it was inevitable that Nikon’s pro flagship would need to offer a more compelling feature set than the existing models."
"In what seems to be a move consistent throughout the industry, the D4's body is strikingly similar to its half-decade-old predecessor. There's no edgy new design to speak of, and all of the controls are exactly where you'd expect them to be. That's not to say Nikon didn't make a few tweaks, however. . . . read more
