An objective mat thanks to its good brightness, its focal range (in this regard, it is not in the exploits of some 18-200 but that's enough to cover a lot of topics) and especially its tiny footprint . A word about the clutter: certainly there are even smaller in the range (14-42 mm F3.5-5.6) but I find it even more versatile 12-35 for a size and weight that (when compared to an SLR) are very small. When the optical quality, no fears. Panasonic has released a resolutely high-end product that is reflected in the price but also the quality of photos.
