Pentax SMC-DA 70mm f/2.4 Limited - Review
The Pentax SMC DA 70mm f/2.4 Limited is an great lens with no really significant technical weakness. The resolution characteristic is generally excellent regardless of the (tested) aperture setting and the resolution distribution is much more harmonic compared to the SMC FA 77mm f/1.8 Limited although it sacrifices a tiny bit of peak performance.

SMC Pentax-DA 70mm f/2.4 Limited
Sometimes when reviewing a lens it's just so hard to actually hand it back after the job is done and this is one of those lenses. It's a superb piece of engineering and has optical qualities that are balanced to just my taste. It is not a macro lens, so very close shots are not possible, but it is ideal for medium range applications and especially portraiture. Highly recommended.
