Ο τύπος είναι σίγουρα κακός στα μαθηματικά πάντως:
"The K20D is equipped with Pentax's moving-sensor image stabilisation system, which has shown itself to be one of the best on the market. Pentax claims that it offers four stops of extra shooting stability, but this is a little optimistic. Using the kit 18-55mm lens supplied, at the longest focal length of 55mm, conventional wisdom says that you need a shutter speed of at least 1/60th of a second for hand-held shooting, so adding four stops to this would give a shutter speeds of 1/8th of a second, but shots taken at this speed show very visible movement blur. Speeding up by one stop to 1/15th of a second produces shake-free shots fairly reliably, which is a three-stop advantage. It may be that the shake reduction works better using lenses with a longer focal length, but with the standard three stops is the limit. Mind you three stops isn't at all bad, and compares well with the performance of lens-based IS systems used by other manufacturers."
1/8 είναι 3 και όχι 4 στοπ κάτω από το 1/60, και 1/15 είναι προφανώς 2 και όχι 3 στοπ κάτω.
