Depends. A number of Pentax's good old lenses are expensive primarily because of rarity. Similar lenses in Nikon mount are more readily availible, and thus noticeably cheaper. The Nikkor 15/3.5 is a ready example. Compare also K105/2.8 (if you can find one) to the equally legendary Nikkor 105/2.5 (which is still availible new, plus readily availible used). OTOH, one of the great things about Pentax is the ability to get great lenses outside of the extreme ranges and pro specs that don't cost too much. You've got to actually try to pay more than $100 for a used 200mm lens, and good used 28s are equally cheap. With some other brands you can't get both good and cheap at once. DJE
