The Panasonic Lumix G Vario 7-14mm f/4.0 ASPH Lens has an impressive wide-angle zoom range of 7-14mm (35mm camera equivalent; 14-28mm), the lens is surprisingly compact and lightweight for casual on-the-go use.
Taking advantage of its wide, 114-degree angle of view, users can easily fit subjects into the frame even when shooting indoors where the distance is limited. The world looks extraordinary when viewed through the lens, allowing photos and movies to be recorded with a uniquely rich perspective. This high-performance lens system achieves outstanding compactness by combining 16 lens elements in 12 groups, including two aspherical lenses and four ED lenses. Image resolution is high from corner-to-corner even at the wide-angle setting. It also features f/4.0 brightness over the entire zoom range thanks to its large-diameter glass moulded lens elements.
This lens is a great match to my 14-140mm kit lens. It has fair amount of fisheye-like barrel distortion, but not nearly as much as a true fish-eye lens has. If it were brighter, cheaper and set up for filters it would be perfect. For an idea of the kind of shots you'll get, think Imax-style video.
As for Samys, this was my first order with them. The order was held up because they wanted to verify more information than what my bank requires for a payment. I'm ok with that, but the Samy's representative was not that honest about what the hold-up was and gave me quite a run-around, to the point where I almost canceled the order. Life is too short to waste time with this sort of thing.
