Nikon Coolpix Lens
The Coolpix series on offer by Nikon is the point and shoot, non-SLR series of digital cameras. There are an innumerable number of models of the Coolpix series manufactured by Nikon. The camera models of the Nikon Coolpixs series have the advantage of an excellent internal zoom lens with remarkable macro capability.
It has also an exclusive range of optical lenses. The lenses used in Nikon Coolpix cameras vary from a fish-eye, which specializes in giving out 183 degrees of coverage to a teleconverter of thrice power that claims to offer coverage of 7 degrees. All of the lenses of Nikon Coolpix are screwed on to the zoom lens at front, excepting the Coolpix 880. Nikon Coolpix 880 needs a UR-E2 step-down ring for its usage. The Nikon Coolpix lenses that screw on to the front of the zoom lens instantly converts the internal optics to an exclusive view.
Some of the Nikon Coolpix cameras also provide exclusive modes in their setup options for the use of converters. The finely incorporated set of optional lenses that are used in Nikon Coolpix cameras currently includes Fish-Eye, Wide-Angle (2), Wide-Angle (3), Internal Zoom, 2x-Tele and 3x-Tele lenses.
Nikon Coolpix camera’s zoom lens cannot be removed like any other 35mm lens from an SLR. But this certainly does not mean that the focal length of the Coolpix cannot be changed. A person can easily use these optional lenses with any of the Coolpix by screwing one of them to internal zoom lens which is sealed at front. By doing so, the focal length of the camera can be changed very easily. The focal length of a Coolpix just measures the distance from the middle of the lens, i.e., its rear nodal point, to the plane at the rear end of the lens where images at infinity come into focus. The focal length tells about two things. It tells how much of the scene the lens embraces and how large the image will be on the focal plane.
There are some shortcomings of every lens and none of them are perfect. But Nikon has done a remarkable job in minimizing the abnormalities in its optional lenses. The Eagle Eye used in Nikon Coolpix has the capability of tolerating the many peculiarities in lenses and thus provides exceptional magnification in the long run.
The flash sensor of Nikon Coolpix cameras are blocked while the converters are attached to them. Thus the onboard flash is lost by a person while they try to use these converters. Just like the flash sensor, the Coolpix LCD monitor will also be blocked by these converters, while a person tries to compose any shots. This is so because the optical viewfinder would be blocked with the use of the converters. As a result of this it would fail to offer the person a true composition of the converted scene. But in actual use a person would find both these problems to be a minor one. And this is because most of the work would be actually composed on the LCD in natural light.
