I have 2 Pentax kit lenses for sale. Both of them were purchased in December '06 used sparingly with UV filters attached... so they are both like new cosmetically and optically. Both of them also include all original accessories, paperwork, and packaging. I've used the Canon and Minolta kit lenses before, and I can honestly say this Pentax is the best of the bunch when it comes to entry-level performance.
My dad and I only upgraded to 16-45mm lenses for slightly wider field of view when neither one of us could get a handle on the ultra-wide 12-24mm we'd purchased (
for sale here).
So I have these 2 kit lenses available... $65 a piece, insured shipping included.
PM me if interested or if you have questions.
UPDATE: 1 lens has sold. I have 1 left.
