As well as being compared against other mirrorless, the Olympus PEN E-P3 is also often compared to entry-level DSLRs and pro digicams. The Olympus PEN E-P3's top rivals come from Sony (such as the Alpha A5000 and the NEX 5N) and Olympus (such as the PEN E-P2 and the PEN E-P1)

compared toMirrorless interchangeable-lens competitors

Generally, some of the advantages of the Olympus E-P3 compared to other mirrorless interchangeable-lens competitors include: it records higher quality movies (1080p @ 30fps vs 720p @ 30fps), has a slightly higher resolution screen (614k dots vs 460k dots), has better image stabilization (sensor shift vs none), has a touch screen and has an OLED screen (OLED vs LCD).

However, on average it doesn't record movies in 24p and doesn't have a screen which flips out.
