Summary: It is hard to describe the D4 without superlatives. This large professional DSLR has a full-frame 16 megapixels sensor which reaches a class-leading ISO 204,800 and can shoot continuously at 11 FPS for over 15 seconds. Image quality from the Nikon D4 is among the very best in all areas.
Pros: Class-leading image noise, Superb dynamic-range, Ultra-fast autofocus, Very fast continuous drive with deep buffer, Extremely fast and responsive, Ultra-short black-out, Good color-accuracy, Flexible self-timer and exposure delay, Highly customizable with plenty of controls, Dual memory cards can...
Cons: Poor Automatic WB in low-light, Overly soft JPEGs, Bizarre, Poor Live-view, not, Exposure Delay, Indistinct ISO button, Rather bulky, No 16:9 guidelines for time-lapse, Asymmetric memory card types
Summary: <img src="http://www.digitalcamerareview.com/assets/48865.jpg" width="320" height="240" alt="" border="0" style="float: right;" /> The past year may be known as the year of the full-frame camera and Nikon has a nicely balanced selection with the D4 for speed and low light, the D800 for its whopping...
Pros: Excellent performance, Stellar image quality, Expanded video capabilities unmatched by competitors, Excellent low light/high ISO performance, Illuminated control buttons
Cons: Only camera to use expensive XQD card for second slot, ISO 205,800 is, perhaps, overkill, D3s may handle noise a little better, Not much of a jump in image quality from D3s
Excerpt: The Nikon D4 continues the tradition of being the alpha male (if there can be such in the camera world) of Nikon’s DSLR lineup. Introduced back in 2007 as the D3, Nikon’s professional full-frame offering has had variants cater to both studio and sports photographers alike (with the D3, D3s and the...
Conclusion: The Nikon D4 is a pro shooter's dream, with controls galore, and a big, bright optical viewfinder. This fully loaded full-frame D-SLR rattles off shots at a quick 10 frames per second, but all of this comes with a rather high sticker price and a steep learning curve.
Pros: Full frame sensor. Every physical control you could ever want. Integrated vertical grip. Shoots at 10 frames per second. Very low image noise. Uncompressed 1080p video output.
Cons: Big and heavy. 16-megapixel resolution. Only one CF card slot.
Excerpt: Faster, smarter, and more lust-worthy than ever, the Nikon D4 ($5,999) is the culmination of a carefully chosen list of features and enhancements, leaving what works and adding what’s needed for the latest in a long line of full-frame (FX) pedigree pro cameras.
Excerpt: The Nikon D4 has some fairly big shoes to fill. Its predecessor, the 12.1-megapixel Nikon D3S was a veritable low-light killer, capable of shooting crisp images even in poor lighting without a flash.
Pros: Separate 91,000-pixel sensor is dedicated to light metering, autofocus and recognizing and adjusting to different shooting scenarios. More rounded and ergonomic design with lower pentaprism still lets you see 100 percent of what you’re shooting through the viewfinder. Back-illuminated buttons hel...
Cons: Second card slot is Sony’s new and expensive XQD format. Built-in mic only offers mono sound. Burst shooting is a frame slower per-second than the competing Canon 1D X.
Summary: Whenever a new piece of top-level gear comes along, there’s a rush by many pros (and more than a few amateurs) to get it right away. While the D4 does outshine its predecessor in many ways, we would not call it an essential upgrade for still shooters who already have a D3s.
