Lenses
It is said that lenses are what makes a picture, rather than your camera body. While the camera is particularly important in digital infrared photography, it is also necessary to choose the right lens for the best pictures and maximum infrared exposure.
P & S wide angle adapters
Since point and shoot cameras have a permanent built in lens the only thing that you could really do to change it is via lens adapters. It used to be pretty common to have a nice wide end, in some cases as wide as 24mm (35mm film equivalent). Unfortunately, for some reason manufacturers started shifting to medium wide, usually around 35mm (35mm film equivalent), which is not very wide at all. This is particularly important for infrared photography as infrared tends to be shot wide in order to capture the landscape. Fortunately the wide end is slowly is creeping back in point and shoot camera designs, this is a welcome change for sure.
It is possible to buy wide angle adapters for point and shoot built in lenses, which are attached to the front via the filter thread or another specialized mounting system.
However, wide angle adapters on point and shoot lenses don’t provide the true wide angles of a dedicated digital SLR lens; the image quality is usually poorer, especially in infrared as wide adapters tend to capture stretched, distorted IR images, much more so than the normal visible light images.
