It is true, but then, of course, a wide angle zoom is more complex than a wide angle prime. Also, the price of the FA*24/f2 went down these last 3 years. Why I do not know. Generally Pentax products (like the other FA* lenses) tend to get more and more expensive. Maybe they made too many?Guess the 24/2 is the best selling FA* lens in history. FA*250-600/5.6 the least of course. :)
How do you know? OK, plastic has some advantages, e.g. it insulates, but that is unimportant in a lens. The only advantages I can identify for plastic parts in lenses are weight and production cost. Maybe somebody else can name other advantages?The ability to hold it's identical physical dimension in varies temperature (before it melt)?
