Both makes of lenses are equally compatible on both makes of camera body. Naturally, Olympus and Panasonic are the two main manufacturers of MFT format lenses. Typically, they have stepping motor autofocus systems which gives rapid and highly accurate performance for stills, as well as delivering virtually silent, smooth focus transitions when shooting movies. Most MFT lenses are impeccably crafted, combining clever design with premium build quality and superb optical qualityĪlthough they tend to be relatively small and lightweight, most MFT lenses are impeccably crafted, combining clever design with premium build quality and superb optical quality. Again, the physical construction of the MFT format lens will be smaller and lighter. For example, a 35-150mm telephoto zoom would give you the same ‘effective’ range as using a 70-300mm lens on a full-frame outfit. Secondly, the actual focal length for any given type of lens is halved. Firstly, the image circle produced by the lens only needs to be a fraction of the size of a full-frame lens, so the optical elements can be made with a relatively small diameter. When it comes to shrinking the physical size of lenses, the advantages are two-fold. At the heart of the MFT system is a comparatively small image sensor that has a 2.0x crop factor, compared with full-frame cameras.
