Leica S with the 30-90mm f/3.5-5.6 Vario-Elmar-S ASPH @ 30mm: Aperture Series 'Pescadero Creek, Downstream'
Get Leica 30-90mm at B&H Photo.
The 30-90mm is a lens I hear about from some Leica S shooters as one that works great as an all-arounder and is good for travel, being about the same size as its fixed focal length siblings.
This example confirms the main weakness with the 30-90mm (seen also in the Rushing Water series and Mossy Boulders in Pescadero Creek series), and ought to be instructive to every prospective user of the Leica 30-90mm.
