Hello Tomcat,
I wonder if your observations concur.
Taking into consideration that the Venue imaging engine is at work here, it does appear that up to F8 across all focal lengths, the Leica maintains better colour contrast and edge resolution. Tonal rendition is consistent on the
ZD but the Leica seems to hold snappier tones at the largest aperture.
For optical performance at the lenses edges, it seems that the Leica is ahead at 14mm but the
ZD catches up trailing slightly behind at 50mm.
From the current samples, the Leica appears to be consistently superior to the
ZD. When prices of the Leica lens which will soon be sold separately from the L1 becomes available, we can have a better idea of the true value of this lens over the well regarded
ZD.
Cheers,
