The 35mm Ltd Macro has been a go-to lens for my professional work. I recently purchased the DA 70mm for the convenience. I was quite surprised at how beautifully it renders colors and how sharp it can be. It seems to handle light more gently than any lens I've owned. I can certainly understand the comparison with Leica optics. Now it's part of my first-tier lens lineup, with the DA 35mm, and the Voigtlander 125mm.
Just a couple shots from my first few weeks of use:
K20D, DA70mm, 1/180 @ f 6.7, ISO 800
K20D, DA70mm, 1/10 @ f 3.5, ISO 800 + flash (Metz AF 58)+ diffuser (Joe Demb)
