Olympus has been a part of the photography landscape since for over 70 years, and was one of the early consumer digital camera innovators. Today, as well as a huge range of (mostly relatively modest) compact cameras, Olympus offers two distinct, but closely related interchangeable lens systems. The E-system, based on the Four Thirds standard, was launched as (and remains) the only ‘fully digital’ SLR system (with no need to support legacy film products). Despite offering smaller than average camera bodies and competitive features, the E-system has not, thus far, delivered Olympus much market share. In 2009 the company launched the mirrorless Micro Four Thirds (PEN) system, to much acclaim.
