Technology has indeed taken a leap - with its advancement it opens a gateway for us to see the world beneath the waves, to capture the details which seemed to be impossible. Nikon - one of the world’s leading brands in innovation - has been established since the year 1917. With its dependability and consistency in the world of cameras it has been a market leader for years.
It is really the functionality of Nikon that has made them so desirable.
Camera controls are intuitive to operate, starting with the upper toggle switch on the rear of the camera, switching between wide angle and telephoto views. The image that you are focussing on is displayed on a small screen on the rear of the camera – there is no eye piece as such, unlike the conventional cameras the you may have seen.
A little pressure on the focus/execute button makes the camera focus and calculate exposure - a full press will cause the camera to take a picture. Most users will use this fully automatic mode.
The screen found at the back of your camera will allow you to review images taken. It makes it possible to review the shots that you have taken, and you can delete the images you do not want to keep. Use the lower toggle switch to step through the shots you have taken.
To quote the words of one professional underwater photographer, "the Nikon D70 allows access to all of the most frequently used buttons and functions. Absent is the Depth-of-Field preview button, which I feel is rather useful but some may not even know exists!"
Indeed, using the additional settings of AF-C (Continuous Auto-Focus) and Dynamic-AF area, one can shoot macro, wide-angle and even portraits by simply and quickly changing the lens. You'll see the benefit of this sharp and precise auto focus system when it comes to chasing and capturing very fast subjects.
Nikon underwater cameras are designed both for professionals and first time users.
