Comparisons between the skiing areas of Kosciusko National Park and overseas should be made with a great deal of caution. The skiing areas of the northern hemisphere are in temperate high latitude areas receiving extensive snow falls. By comparison, the Kosciusko resorts are in the same latitude as the African side of the Mediterranean Sea! In addition, ski field developments in Australia are all at or above the tree line, and in ecological terms are effectively far higher in the mountains than most of their overseas counterparts. There are very few examples overseas of ski resorts which are developed in environments as restricted in their continental distribution or as fragile as the alpine area of Kosciusko National Park. The international importance of the Park was officially acknowledged in January 1977, when it was designated a Biosphere Reserve under UNESCO' | Comparisons between the skiing areas of Kosciusko National Park and overseas should be made with a great deal of caution.

- | A 50 mm lens is normally supplied with the camera as the standard lens. It covers an angle of view roughly equivalent to normal forward vision. It is a generally useful bland compromise giving restricted visual effects. It will focus to 0.5 metres at which distance a page of this magazine just fills the frame. Far too big for wild flower studies. Pointed at a landscape all but the most prominent features flatten out leaving the centre of interest framed with a devastatingly blue sky occupying 20% of the frame.

By buying a second-hand camera, two additional lenses and a close-up set one can develop an infinite range of vision. Second-hand cameras with built-in light meter sell for around $100, a zoom lens a bit more, a 28 m.m. lens a bit less, and close-up sets next to nothing. Add later a teleconverter for $30. About $300 its still not much more than 50% of a basic new camera and restrictive standard lens. Any camera is just a black box - it is the lens that shows you the world. The added weight of all the lenses is around one kilogram. |
