This is not a joke, but a real auction on ebay for a Canon 5200mm (LONG) f14 prime lens.
This is a very rare Canon 5200mm photographic lens. THE largest & most powerful prime lens ever created for dedicated SLR photographic use. Made in Japan. It is my understanding that a customized SLR/DSLR/EF mount can be created/included by the team of optical engineers who presently look after the lens. Due to its large size, it may be better suited to astronomy applications & others... It takes two strong people to lift the lens. It could also be mounted on a customized truck or SUV. A large geared or motorized support head would be needed to get the most out it. The magnification of this lens is truly staggering. If mounted to a Canon HD XL series video camera for example, a reach of 1000x optical (at least) would be possible (approx 37,500mm). The lens could also be mounted to HD & cine cameras. Manual focus & drop-in filters can be used. With so few ever built Canon spent a tonne on the R&D, not to mention the manufacturer of this lens. The Canon factory picture shows the lens mounted to an SLR camera (circled in red) – this will further give you an idea of its size. As the lens is so rare & so unique, it's fair to say that it's a collectors item & attraction in itself. For Canon collectors & owners of the Canon EF 1200mm F5.6 lens - quite simply your Canon collection is incomplete with out it.
Starting bid is $45,000. See photos and details at: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180438980987
