The Nikon D4 DSLR is equipped with a new Nikon FX-format CMOS image sensor (imaging size of 36.0 x 23.9 mm) and EXPEED 3, the latest image-processing engine specifically optimized for digital-SLR cameras, making it the next-generation flagship Nikon digital-SLR camera with the ultimate in versatility and functionality that offers superior image quality rich in detail along with excellent high-speed performance. It has an effective pixel count of 16.2-million pixels and offers superior image quality under a broad range of lighting conditions with its image sensor supporting an incredible range of sensitivities from ISO 50 to ISO 204800.
The new 91K-pixel (approximately 91,000 pixels) RGB sensor supports the Advanced Scene Recognition System, which is able to recognize human faces even when images are framed using the optical viewfinder. In addition, the Advanced Scene Recognition System offers significant improvements in AF, AE, i-TTL flash control and auto white balance (AWB) control accuracy.
The 51 focus point AF system has been improved with faster initiation of autofocusing and the ability to detect and focus on subjects with less lighting. In addition, 11 focus points are fully functional when lenses with a maximum aperture of f/8 are used. All of this means more precise autofocusing when super-telephoto NIKKOR lenses are used with teleconverters (2.0x). The Multi-area Mode Full HD D-movie movie recording function is capable of recording full-HD movies at 30 fps and offers three movie recording formats for selection according to recording conditions or creative intent.
In addition to built-in wired LAN features, the D4 also supports high-speed image transfer via wireless LAN when the new, compact, easy-to-use Wireless Transmitter WT-5 (available separately) is connected to the camera. The D4 is also equipped with a number of new functions that support a more efficient workflow for professional photographers, including one that allows users to add IPTC (International Press Telecommunications Council) information to images.
It may sound redundant, but this camera is tops when photographing sports or fast moving wildlife. Its ability to track and focus is the best I've ever experienced within the Nikon family. If the first picture of a burst in action is not in focus, its definitely the second one. I would say about a third of the time, the first shot is in focus and 2/3 by the second, unless I've done something wrong (its not the camera). Low light-no problem. From an ergonomic standpoint, I have big hands and it fits very well. Its weight is off-set by the rounding of corners and balance/weight distribution. Its getting an upgrade, but the value of this body will last a long time.
The Nikon D4 camera body is well suited for photographing very fast wildlife on the run. The below photos of a cheetah running a straight 100 meter track were taken at Continuous High Speed shutter release, a shutter speed of 1/1000 of a second, an aperture of f/4, focal lengths of 300mm and 400mm, ISO values between 1250 and 1800, Center Weighted Metering, and Auto White Balance.
Love the camera itself but I have put less that 500 shots on it and got an error code that required going back to Nikon. Im hoping this is a flute. But when it works its an awesome rig.
Use camera for covering sports and nature photography. The Nikon D4 is fast, quick auto focus, great image quality and file size and outstanding in low light with the high ISO's.
Even two years after it's release, this camera stands the test of time. It's a solid workhorse with fantastic low light image quality that feels and sounds as a pro camera should! Until... You have any issues with it and then it's all down hill if you are out of the warranty period. This was one of the first cameras released so maybe that's the the issue with my body. In any event, here's my story. 13 months after I purchased it at Adorama, the mic input went out on me during the middle of a video shoot for a client. I sent it to Melville, NY for an out of warranty repair that took 3 weeks. 9 months later in the midst of a photo shoot for another client, any and all lenses stopped responding. In both instances a back up D800 saved the day. Out to Melville, NY it went again this time for a little over a month with some electrical related issue that had to be repaired again out of warranty. When I received the camera back, it worked for all of 10 minutes before it stopped working and wouldn't even turn on. In less than a year I've had more issues with my Nikon D4 camera than I've had over the previous 5 years across 4 different Nikon bodies (D300S, 2-D7000's and a D700) that all saw more video and photography action than my D4. I pride myself on taking good care of my equipment, but at least in my experience, this is not your daddy's war camera and thus it gets 1 star for its durability and 5 stars for it raw technical prowess.
Tried to go less camera after using the D3 and associated Nikkor lenses. Process too difficult. So I Upgraded to Nikon D4Camera w Nikkor 80 to 400 mm Lens. I'm happily in the saddle once again. I cover sports action for the local college and some high schools. I have all the range I need for football, baseball, golf (shoot after ball is struck), basketball (use no flash) and tennis. I prefer the zoom over multiple lenses to obtain the cover I need. Convenience wins over multiple lenses requiring lens changing as you go. This described combination consistently has produced outstanding images for daily print media. Richard.
Just got the D4 body yesterday and have been busy shooting with D3. The D4 feels real natural in my hands as did the D3 did after F-100. Only complaint: How do I load Provia 100F into this thing?
I do not know what DSLR offer little more, AAA D4.
Great in low light situations. Very quick on focus Ergonomics make it very easy to handle
It doesn't get any better than this. I was shooting a Canon 7D and 5D Mark2, both great cameras. I like the external control buttons a lot. I thought I would miss the big Canon control wheel, but I don't. I do miss the C1, C2 and C3 custom control and Nikon banks are a poor replacement. I think I like the chip set in the Nikon better than my Canons. Tones seem to be more natural without correction. This camera is easy to shoot, and while it is expensive, I don't think you can find a better camera.
