17-70 SDM .. the versatile
This must be the most versatile DA lens from Pentax. You can use it almost in every context, .. landscape, portrait, arcitecture, .. even macro (closest focus 28cm, magnification rating 0,31x). Very sharp from f5.6, and razor sharp from f8 through f11, that's whatever focal lenght. Best tested result with f10/33cm.
SDM technology makes focusin process fast and silent. Manual focus ring is full time operational (that’s even when AF is on). That’s more than a walk around lens.
no WR, .. no ED
