The User’s Review: The differences between Pentax SMC DA L and DA II (18 - 55mm) Lenses

Some people believe that the DA II lens produces better images. And the two models do have differences physically. At this time, I have both lenses side by side to demonstrate them (Figs 1 - 2 and Table).

The key difference is the quick shift (QS) in DA II. The lens releases the gear with the focus-driving motor in camera body and allows manual adjustment of focusing once the auto-focusing finishes. I use QS for two purposes (1) manual focus adjustment if I can do better than auto-focusing, and (2) for storage, I set the distance ring to infinity to reduce the lens length, without switching to the manual focusing mode on camera body.

The DA L lens was sold online for USD 37 including shipping, on May 20, 2011.
