However, f/1.4 lenses with 10-to-1 zoom ranges are easy to find on 8mm movie cameras. Question: why don't camera makers offer super speed lenses on subminiature format still cameras? The Pentax 110 SLR is a cute toy with its 24mm/2.8 (or whatever it comes with), but with an f/1.0 or faster lens it would make available darkness fans such as myself wake up and take notice.
