The image sensor format, between those of larger SLRs and smaller point-and-shoot compact digital cameras, yields intermediate levels of cost, performance, and convenience. Offering long reach with an advanced feature-set and optical design, the M.Zuiko Digital ED 40-150mm f/2.8 PRO from Olympus is a versatile 80-300mm equivalent telephoto zoom for Micro Four Thirds mirrorless cameras. Thus, the Four Thirds System has crop factor (focal length multiplier) of about 2, and while this enables longer focal length for greater magnification, it does not necessarily aid the manufacture of wide angle lenses. 80-300mm (35mm Equivalent) Aperture Range: f/2.8 to f/22. For example, a Four Thirds lens with a 300 mm focal length would cover about the same angle of view as a 600 mm focal length lens for the 35 mm film standard, and is correspondingly more compact. The cameras name pays homage to Olympus iconic OM-1 film camera, introduced 50 years ago, and even carries the Olympus name on the viewfinder. The size of the sensor is significantly smaller than for most DSLRs and this implies that lenses, especially telephoto lenses, can be smaller.

Today, OM Digital Solutions (OMDS) announced the OM-1, a 20MP flagship Micro Four Thirds interchangeable lens camera that is the first under the company’s OM System brand. Lens design has been tailored to the requirements of digital sensors, most notably through telecentric designs. Many lenses are extensively computerised, to the point that Olympus offers firmware updates for many of them. We round up the best Micro Four Thirds lenses, including primes, ultra-wide angles and super-telephotos Included in this guide: 1 Panasonic Lumix G X Vario 12-35mm f/2.8 II ASPH Power OIS Check Price 2 Panasonic Leica DG Nocticron 42.5mm f/1.2 ASPH Power OIS Check Price 3 Panasonic Lumix G X Vario 35-100mm f/2. Unlike older single-lens reflex (SLR) systems, Four Thirds was designed from the start to be entirely digital. Proponents describe it as an open standard, but companies may use it only under a non-disclosure agreement. Patent 6,910,814 seems to cover the standard. The system provides a standard that, with digital cameras and lenses available from multiple manufacturers, allows for the interchange of lenses and bodies from different manufacturers. The Micro Four Thirds system invented modern mirrorless photography and, with more than a decade of lens development, has something for every photographer.
