![]() ![]() The internal construction of the lens includes aspherical elements as well as 5 extra low dispersion elements, 2 Super HR elements and 1 HR elements. ![]() Externally the lens has good weather sealing. That is a good thing if you would like to keep the same DoF across the focal length. The maximum aperture of the lens is a constant f/4. You could shoot wide angle as well as little bit of birding and a lot of portraiture as well with this lens. With a focal length of 12 – 100mm, which on a 35mm sensor format becomes the equivalent of 24 – 200mm, this lens is effective for a wide range of photography. # 3 – Olympus M.Zuiko Digital ED 12-100 f/4 IS PRO lens It is able to resist inclement weather giving you extra protection should you choose to shoot even when conditions are not perfect. Finally, the lens has great weather sealing. system which is available on select Panasonic Lumix cameras. The mechanism is compatible with Panasonic’s body based Dual I.S. It reduces blur when shooting with slower shutter speeds. The 12-35mm also comes with what Panasonic states as Power O.I.S. The aspherical elements suppress aberrations and distortions which are normal in wide angle lenses. ![]() The Nano surface coating of the lens ensures flares and ghosting are suppressed. The internal construction of the lens consists of four aspherical elements, one UED element and one UHR element. The widest aperture is not what you would be shooting in though. A rounded 7-blade aperture helps in creating nice bokeh. The maximum constant aperture of the lens is f/2.8. The crop factor of the lens makes this a 35mm format equivalent focal length of 24 – 70mm. This micro four-thirds system lens comes with focal length of 12 – 35mm. # 2 – Panasonic Lumix GX Vario 12 – 35mm f/2.8 II ASPH.POWER O.I.S. The best bit is that the lens comes in a tough weather resistant construction that promises workability even in the worst of weather conditions. The lens has a unique focus clutch mechanism that needs a bit of getting used to. ZERO coating has also been provided to suppress lens flares and ghosting common with wide aperture lenses. These elements produces better clarity and color in the frames. Apart from these the lens also has 1 DSA, 2ED, 1HD and 2 HR lens elements. These suppresses aberrations which are quite usual for wide angle lenses. The 12-40mm f/2.8 comes with 1 aspherical ED & 2 standard aspherical elements. What is, however, is the capability of the lens to produce distortion free images. But bokeh isn’t a priority for landscape shooting though. The lens diaphragm is made up of 7 rounded blades. The maximum aperture possible on the lens is a wide f/2.8 which promises nice bokeh. It covers the essential focal length range that promises great landscape photos. When mounted on a 2x crop MFT system the effective focal length becomes the equivalent of a 24 – 80mm. This wide angle medium tele-lens has a focal length of 12-40mm. # 1 – Olympus M.Zuiko Digital ED 12-40mm f/2.8 PRO lens In this review we look at the best wide angle landscape lenses designed for the micro four-thirds system. However, the ultra-wide angle focal length lenses ensure that you have a few workable landscape lenses to choose from. The 2x crop takes most lenses beyond the 50mm threshold. This system with a crop factor of 2x, are at a handicap to find workable wide angle lenses. The micro four-thirds system has seen a surge in the availability of new lenses.
