A word that isn't misspelt often, but is definitely misapplied often, is "zoom". The non-working K2 I have came with a "zoom" lens that looked like a 100-200 zoom in the eBay photo but proved to be the SMCP-M 100/4.0 macro. I didn't complain, because I preferred the macro. However, it does seem that people with no clue about photography often described any lens much physically large than a standard lens as a "zoom"; I think this stems from watching television, where any narrow-angle shot is thought of as "zoomed". -- PDML means I get more e-mail than spam!
