![]() Even their PEN mirrorless series offers extensive bracketing options, advanced metering modes, Bulb exposure and much more. Olympus has the tradition of making feature-rich cameras with advanced functionality across the board. The Olympus lineup is divided onto the entry-level PEN series and the OM-D class which is split among three levels of advanced cameras. This required collaboration between the camera and lens, so it is not available on all body and lens combinations. Olympus later implemented an equivalent system. When Panasonic started with built-in stabilization, they invented Dual IS which combines both in-body and optical stabilization to deliver further improvements. Since then, 2/3 of their new Micro Four-Thirds mirrorless cameras include it. Panasonic initially went with in-lens optical image-stabilization until they added IBIS to the GX8 in 2015. They have been perfecting their system for years and now offer best-in-class stabilization with up to 7-stops of efficiency using a 5-axis sensor-shift system assisted by GPS. ![]() With state-of-the-art sensors, there is little performance difference left between these two AF systems.Īll Olympus mirrorless cameras feature built-in image-stabilization. Olympus added Phase-Detect AF to many of their cameras, although Contrast-Detect remains in use among their entry-level offerings. They invented the Depth-from-Defocus technology to improve the performance of Contrast-Detection. Panasonic used Contast-Detect AF on every single one of their mirrorless cameras. The approach taken by these two companies differs on several key features. Olympus added last year the OM-D E-M1X reviewed here Olympus OM-D E-M1X for professional action photographers. They each maintain multiple series of Micro Four-Thirds mirrorless digital cameras, from entry-level to high-end professional models. Panasonic and Olympus continuously introduce new Micro Four-Thirds cameras. Physics puts Micro Four-Thirds at a 2-stop disadvantage in comparison to Full-Frame and just over ½-stop compared to APS-C. but the intended sensor-size is identical. The name Four-Thirds refers to this aspect-ratio, while the term Micro was added to describe a shorter flange distance The distance between the sensor and lens mount. Both these platforms were designed for a 2X crop-factor and 4:3 aspect-ratio. The standard behind Micro Four-Thirds is based on an older system used by now discontinued Olympus DSLRs. This head start, plus the fact that it is actively developed by two major digital camera manufacturers, make it the most extensive mirrorless system in terms of cameras and even more so when it comes to lenses. It was launched in 2008 jointly by Olympus and Panasonic. Micro Four-Thirds is the original mirrorless system.
