Summary: Despite the fact that the Nikon D4s does not offer significant advantages in image quality when compared to the D4, Nikon incorporated a few important changes to the D4s that make the flagship camera noticeably better than its predecessor.
Conclusion: If you're a full-time pro, all the the little things about the D4s add up to make getting a couple of D4s a no-brainer. I whine about the loss of most of the external AF controls (buttons and spinning dials do not replace dedicated levers), but the new AF system already knows what I want it to do,...
Summary: Although the D4S might look like its little brother the D4, there are some subtle changes that make it a better value and a better camera. Take the 11fps shooting, add in full 1080 60p video and super-fast AF; this baby has your ticket to fast professional performance.
Pros: 60p in full 1080HD, Rugged build quality, Lighter than comparable cameras
Cons: Not all buttons easy to find, ISO not as easy to change on the fly, Live View monitor has lots of glare when in sunlight
Conclusion: Given its heritage and flagship status, it was clear coming into our Nikon D4S review that the question we'd be looking to answer wasn't so much whether this was a great camera, as how great it might be.
Pros: Excellent, tank-like build quality, Same great ergonomics you know from the D4, Big, bright viewfinder with 100% coverage, Dual card slots, Excellent overall image quality, Outstanding low-light capabilities, Very good dynamic range, Superb performance, Even faster burst speed with continuous AF/...
Cons: Fairly minor upgrade of the D4, especially if you only shoot RAW files and aren't a movie shooter, Large, hefty body (but that's par for the course in a pro camera), XQD card format hasn't been widely adopted (but you can still opt for CompactFlash cards if you want a more broadly-accepted format...
Summary: It is hard to describe the D4s without superlatives. This large professional DSLR has a full-frame 16 megapixels sensor which reaches a class-leading ISO 409,600 and can shoot continuously at 11 FPS for over 15 seconds. Image quality from the Nikon D4S is among the very best in all areas.
Pros: Class-leading image noise, Excellent sharpness, Superb dynamic-range, Ultra-fast autofocus, Very fast continuous drive with deep buffer, Extremely fast and responsive, Ultra-short black-out, Flexible self-timer and exposure delay, Highly customizable with plenty of controls, Manual focus assist d...
Cons: Poor Automatic WB in low-light, Stiff 8-way controller, Indistinct ISO button, Bizarre Auto ISO, Poor Live-view, not Exposure-Priority, Exposure Delay mode hidden in menu, Heavy and bulky, No 16:9 guidelines for time-lapse, Asymmetric memory card types
Summary: The jump in continuous shooting speed of a frame a second might not sound like much, but it will certainly be good news for professionals, while the similar improvement in AF performance will also be welcome.
Pros: High ISO performance; Improved continuous shooting; Enhanced video performance
Summary: Nikon D4s review: Nikon’s D4 replacement is a true workhorse of a camera, but has enough changed to warrant an upgrade? Find out in our Nikon D4s review. After weeks of cloak-and-dagger secrecy and sneak previews in glass cabinets, Nikon finally announced its Nikon D4 replacement.
Excerpt: It's been two years since Nikon introduced their flagship SLR, the D4. While that camera has undoubtedly stood the test of time, Nikon has decided that it's time for a refresh. That camera is the D4s which, on the surface, doesn't look much different than its predecessor.
