Gosh. All I wanted to know was why the DA14mm is so large and heavy? (I know now - thanks Alex). Now everyone is arguing about lenses not being able to magically transform into other lenses, calling each other "jackass" and/or "stupid" - even arguing about who's p**is is the biggest. It's all good fun I suppose.
I still believe Pentax however, when they say (in the owners' manual) that the 5.7-16mm "fisheye zoom" lens on my Optio 43WR is equivalent to 37 - 104mm in 35mm format. Now, I know that there are those who will shrug their shoulders and shake their heads in disbelief at my "foolishness" and "gullibility" in believing the advertising - but we will just have to agree to disagree. Now I'll just sit back and read the continuing stream of invective from all sides.
