They are good options if you don’t want to splurge on digital SLRs, but still demand better-quality images than what compact cameras deliver.
Also known as mirrorless interchangeable lens cameras, most have the large image sensors and lenses that allow DSLRs to shoot high-quality photos.

However, there are two main drawbacks: First, Micro Four Thirds can’t match the autofocus speeds of DSLRs in continuous shooting mode. Second, they can’t track moving objects as well as DSLRs.
