The E-30 was introduced 3 years earlier than the G3 and that is quite a big difference as far as technology is concerned. Each of the cameras have different body design with the Olympus E-30 being a Mid-size SLR camera and the Panasonic G3 being a SLR-style mirrorless camera.

Before getting straight to a complete comparison, here is a brief introduction of how the E-30 scores vs the G3 in relation to portability, imaging, features and an overall rating.
