Nikon D3S, The Perfection of D3

Nikon is a Japanese camera brand that has proven reliability and quality. Entering the digital age, Nikon does not want to miss with the demands of consumers who want digital quality is not inferior to the quality of celluloid film.


By prioritizing the quality of color are qualified, Nikon D3S re-issued the latest variant in the class professional digital SLR cameras. With a series based on the D3 that has a resolution of 12 mega pixel Full Frame (36 x 24 mm), 51 point of view sensor, Nikon D3S offers several additional advantages such as high definition video recording capabilities with a stereo mic and 720x1280p HDMI HD video output, an LCD monitor size 3.0 "922,000 pixel resolution, ISO 200 to 12.800 can even reach 102.400! What is with this ability can be dismissed the notion that the camera has a high pixel resolution is not supported with high ISO will produce a dark image results when exposed to field a low-light photos?

This camera agility was claimed as a full-frame DSLR camera with the ability to capture the fastest 9 frames per second! Matter of convenience and shapes, also claimed as Nikon camera that has an ergonomic shape and comfortable when grasped. Having a sturdy camera body with a magnesium alloy cast and the battery life is excellent even when the LCD video screen is activated.


Of course the values ​​of more cameras this one is followed by the word "but ..." Indeed, even after Nikon announced the launch of D3S in 2007, not a few commentators have questioned why Nikon does not use a sensor with higher resolution. Especially now, four years later, 12 million pixels look more conservative than competitors D3S new. Indeed, the penalty in this resolution means that image quality is more stable at high ISO-at least this is the justification of the Nikon. And photographers who often shoot in low light conditions would probably agree. But the D3 is the first model is already reliable handle high ISO, and extra-high ISO capability in D3S looks as if to answer critics who never appeared. It seemed most people will not take pictures with higher ISO of ISO 3200, let alone 102,400.


In addition to the sensor resolution of the issues that aging earlier, there are some other minor complaints about 3DS. White balance, for example, not so good under artificial light; although admittedly not many cameras that can handle this one aspect right. AF arrangement is also relatively small compared to its viewfinder area. D3S video recording capability is also somewhat disappointing, although in fact better than the Nikon digital SLR ever. With a resolution of 720p, 24fps, the video quality may be a good sort, but still below most DSLR rivals; also no option to record in MPEG format. All-in-all, D3S is a camera that has almost all the specifications to become a professional DSLR camera that should be owned by any photographer who wants to have a camera with very good performance. Finally, if you are looking for is flexibility and speed, and high resolution can be 'sacrificed', then the Nikon D3S is a solid choice. (Gadget / roc)
