Leica makes a range of slide projector lenses. These are available in two different mounts, the older P mount shared with most, if not all, of Leitz' and Leica's earlier projectors and with the current P2002, and the newer P2 lenses used by the P150, P300, and P600 projectors. The two families are optically identical and vary only in the mounts for the lenses between 60mm and 200mm in focal length; the P series includes lenses both shorter and longer than this, though, including such specialty items as the 35mm f/2.8 Elmaron -- talk about being able to show slides in a phone booth! -- and a 300mm f/4.3 Epnor which would be suitable for projection down the nave of the Cathedral of St John the Divine. There are also two zoom projection lenses available in both mounts. For normal purposes, the shorter the focal length, the shorter the distance necessary to fill an entire screen. A 35mm lens will fill a screen at a remarkably short distance, 7 or 8 feet. In America, where rooms are a bit larger than in Europe or Asia, slide projectors often come with 100mm or longer projection lenses, but in Europe, the land of apparently small rooms, an 85mm or 90mm is normal. (And how many of you guys remember the lamented Prado Universal for which the 2.8/35 Elmaron-P lens was introduced in 1968? There were attachments for hooking microscopes or test tubes up to the Prado Universal projector, so that an instructor could sit with a student at his or her desk and project the results onto a screen immediately in front of them. I owned one, once, and stupidly sold it -- it was one of the neatest Leica toys I've every had.) The P150 comes with a so-so, not-good, not-bad 85mm f/2.8 Hektor-P2, but this can be, and really should be, replaced with the much more satisfactory 90mm f/2.5 Colorplan-P2, for glass-mounted slides, or the Colorplan-P2 CF (curved field) for cardboard-mount slides. An even finer optic is available in the 90mm f/2.5 Super-Colorplan-P2. I do not have a current Leica pricelist in front of me, but I would guesstimate that the Colorplan lenses are available for under $200 and the Super-Colorplan around $325. Medium-format projectors are a step beyond this. There, the normal projection lens is around 180mm or so in the US, 150mm in Europe. (And, stunning as a 35mm slide can be, a "superslide" (4cm by 4cm) is even better, and a 6cm by 6cm slide MUCH better. Fall is coming -- and my Rolleiflex and I will be firing off some E100S of those turning leaves.) Marc email@example.com FAX: +540/343-7315 Cha robh bas fir gun ghras fir!
