In fact, almost any still camera, movie or video camera interchangeable lens that has a flange focal distance greater than or marginally less than 20 mm can often be used on MFT bodies via an adapter. While these so-called "legacy" lenses can only be used in a manual focus, manual aperture control mode on MFT cameras, hundreds of lenses are available for use, even those that survive for cameras no longer in production.

Advantages of Micro Four Thirds over DSLR cameras
- The smaller sensor size gives deeper depth-of-field for the same equivalent field of view and aperture. This can be desirable in some situations, such as landscape and macro shooting.
- The shorter flange focal distance means that most manual lenses can be adapted for use.
- Greatly increased sensor size (5–9 times larger area) gives much better image quality, e.g. low light performance and greater dynamic range, with reduced noise.
- Interchangeable lenses allow more optical choices including niche, legacy, and future lenses.
- Shallower depth of field possible (e.g. for portraits).
- An advantage of wildlife shooters and birders in particular lies with the fact that old 35mm telephoto lenses become extreme telephotos due to the system's 2x crop factor.
Practically speaking, this means that a 50 mm lens on a MFT body would have a field of view equivalent to a 100 mm lens on a full frame camera.
Happy to hear that?
