Nikon has brought in the D4 with the latest of features enabling it to become a powerhouse performer among the current crop of high end single lens reflex cameras. It is indeed an incredibly impressive camera with an intention of catering to the demands of its professional user base.
The new Nikon D4 Digital SLR is now the flag bearer of the high end SLRs with a series of additional features which fully complements the great camera that it is. It is a fully loaded monster of a camera which feels and looks its part. The gadgetry apart it adds a comprehensive list of improvements to a feature set, which was already the best in the industry. It features a new 16.2 megapixel full frame sensor, 11fps shooting, Full HD video and a number of unique features. The camera has been designed to offer better performance than the D3s in low light, with an increased pixel count, lower noise at high ISO settings and increased dynamic range. The camera features improved subject detection and tracking with a new AF system. The Nikon D4 has a solid body with a magnesium alloy core and is weather sealed. It certainly feels solid in the hand and extremely ergonomic and comfortable in use - the grip when used in landscape mode is deep and has an excellent grip. The comfortable handling seems to aid in making the camera feel lighter / smaller than it actually is and it doesn't feel unwieldy or overly large despite having a built in vertical grip. The camera has a wealth of ports on the side, including: flash sync terminal, 10 pin remote terminal (both on the front), accessory port, USB, headphone, microphone, Ethernet and HDMI. The Ethernet connection supports HTTP or FTP uploads so that you can upload shots straight to the internet, a useful feature for sports photographers at the Olympics, who will be provided with network connections. Buttons on the camera have been redesigned, with a new AF switch and button that allows you to change the AF mode without taking your eye away from the viewfinder. Vertical shooting has been improved with a mirrored layout whether using landscape or portrait shooting. There is a dedicated movie record button, a vertical function button and a re-designed shutter button position with a ""more comfortable"" 35 degree angle compared to 28 degrees which is designed to be more comfortable for extended periods of shooting. The camera gives better battery performance despite the new battery being smaller than the battery in the D3s. A new law recently introduced means they can't use the D3s battery Shutter response, focus, switch on time and shot to shot time are all excellent. This is a really fast camera. Continuous shooting is extremely quick, and in addition to the 11fps shooting mode, it's possible to shoot up to 199 shots at 9fps in JPEG Fine mode without slowdown. There was some benefit shooting with the XQD card, allowing more shots to be taken without slowdown. The Nikon D4 also offers the best video output of all Nikon Digital SLRs to date, with Full HD recording, 20 level adjustments for the microphone in port, and a headphone out port with 30 level adjustments, visual sound level monitoring and professional level sound recording with the ME-1 microphone. ISO200 to ISO204,800 is also available for video recording and it's possible to take a live frame grab whilst recording video at 2 megapixels. Video is recorded as H.264 with B frame compression and the camera provides a clean HDMI out at 1080/720 with no compression allowing video to be recorded to an external device beyond the 29 minute limitation recording internally. Index marking is available to assist with editing. Multiple frame sizes are available FX, DX and a pixel matched 1920x1080.
