I'm thinking about getting these lenses for my K1000. They're both manual zoom/manual focus so they'd be fine in the respect for my camera. Both around $100-200. I'm just looking for any opinions on these lenses, good or bad. It would be nice to have some all-purpose lenses since all I'm working with right now is a 50mm lens, but if I'm going to be sacrificing quality then I might rethink this purchase and save up for something better. As a side note, I might be picking up a Pentax IST D within the next year, depending on how well the job-hunt pans out. It would be great to have lenses that work with this and with my current camera (either as a backup or for b/w film). Would the lenses I mentioned work well with this, or would I need something specifically engineered for digital use? Thanks!
