As well as being compared against other mirrorless, the Olympus OM-D E-M1 is also often compared to pro DSLRs, entry-level DSLRs and pro digicams. The Olympus OM-D E-M1's top rivals come from Olympus (such as the OM-D E-M10 II and the OM-D E-M5 II) and Panasonic (such as the Lumix DMC-GX80 and the Lumix DMC-G3)

compared toMirrorless interchangeable-lens competitors

Generally, some of the advantages of the Olympus E-M1 compared to other mirrorless interchangeable-lens competitors include: it has a much higher resolution screen (1,400k dots vs 921k dots), slightly larger viewfinder (0.71x vs 0.59x), has better image stabilization (sensor shift vs none), has a touch screen and has a weather sealed body.

However, on average it records higher quality movies (1080p @ 30fps vs UHD @ 30fps), doesn't record movies in 24p, doesn't have an OLED screen (LCD vs OLED), is older (august 2013 vs february 2015) and is slightly larger (prosumer size (130×94×63 mm) vs mid size (122×71×44 mm)).
