Panasonic 12-35mm f/2.8 X HD weatherproof lens
introduction
version I released May 2012, this is Panasonic's 1st weathersealed lens and its first zoom lens with constant aperture throughout the zoom range
giving a 35mm equivalent field of view of a 24-70mm lens, it is half the size of its f/2.8 24-70mm full frame counterparts, with much faster and more accurate AF of still subjects, but of course does not offer the same ability to have narrow
depth of field (DOF)
nevertheless, the f/2.8 aperture combined with its compact size, weatherproofing, high image quality and
image stabiliser means it will be an awesome travel lens in particular.
version ii announced in Jan 2017 offers better weathersealing, and smoother aperture variance when zooming
both lenses can support Dual Sync IS (version I needs firmware upgrade)

reviews
-
very sharp throughout the frame wide open but sharpest at f/8 in the centre
complete absence of CA in the centre and only small amounts in corners where there is also some astigmatism
some vignetting wide open but this is further corrected by software
easily correctable minimal distortions
very nice bokeh
-
-
sharp wide opens except wide end at closest focus and infinity in the corners
mild CA and distortion wide open at wide end
bokeh a little nervous at wide end but smoother at long end of focal lengths
susceptible to flare
but beautiful compact lens for an f/2.8 zoom, although a touch heavy for the smallest cameras
