I don`t care what is writen on the lens, but I don`t thing that one 21mm lens need to be more expensive just for being 21 instead of 20. Opticaly Pentax lenses are not superior to other lenses. They are small and that is great, but they are also slow and that is not so great.
First, thank you.
Secondly, using your counter-example, I question whether an 18 year old, 20mm f2.8 non-L (consumer-level) Canon lens provides the same optical quality as the DA 21mm. And even if it does, what are you getting? It's not just size, but weight (or lack of weight) that matters in the marketplace. The Canon weighs 14.3 oz; the Pentax DA 21mm weighs 5.5 oz with hood. That difference is significant to me and I don't think it's unreasonable that it carries some value in the marketplace cost wise--especially if you are expecting to carry a few other lenses. The 2.8 vs. 3.2 aperture speed difference, to me, doesn't matter much in that focal length.
Oh, BTW, please do show me a faster non-Pentax lens that weighs under 8oz in that focal length. I'll go easy on you and let you throw in the 15mm, 40mm, and 70-ish mm focal lengths as well. They are "superior" optically because no one else does it.
