Originally posted by baro-nite I'm curious about the 16-45, as it has been discontinued for some time. Those are pretty easy to find used at a lower price. The 17-70 is tempting, though.
You're right about the 16-45, it is often available used on the PF Marketplace for much less than this sale price for a brand-new one. But the DA 17-70 is much rarer to find used, and when it is sold, it's for about $350 anyway, which is the asking price on this brand-new model. I'm concerned about the SDM reliability, though, because who knows if these DA 17-70s that are being sold by the website are newly manufactured (in 2012, when apparently SDM problems were fixed for newly made lenses), or older stock lenses that have a ticking-time-bomb of SDM failure. The reason the 17-70 tempts me, though, is the nice range and the optical quality that some have praised; I'm sure it's better than my DA 18-135 but is it really worth me having both lenses?
