The wide-angle to telephoto zoom range of the Leica X Vario offers great scope for creative composition, whether used for capturing indoor scenes, sweeping landscapes or intimate portraits.
I don't see how this lens is especially useful for any of these needs. Creative composition will be limited by such a slow lens, and shooting indoors at f/3.5 isn't ideal. An EFL 28mm isn't going to produce particularly "sweeping" landscapes. You can pretty much forget about shooting "intimate" portraits using f/6.4 either as much of the background is likely to be in reasonably distracting focus.
The camera will no doubt have Leica build quality and handling with the usual traditional manual controls, and I'm sure the lens will be of excellent quality despite its very mediocre specs, but I can't really see anything here to tempt anyone whatsoever (except the red dot).
Leica's M-series, coupled with one of those great lenses, still has something unique and unparalleled to offer the serious photographer despite the enormous price. However, even if the rumored price of the X Vario (north of $3000... without the optional viewfinder ) were reduced by half, offerings other manufacturers (especially Fuji) just blow it out of the water.
I don't want to be over-critical of a new untested camera, but can anyone help me out here?
