Our Verdict
OM SYSTEM OM-1
OM SYSTEM OM-1 Mark II
The OM SYSTEM OM-1 Mark II is an updated version of the OM SYSTEM OM-1. Physically, the cameras are nearly identical, though the OM-1 Mark II does add rubberized control dials that offer a bit more grip, as well as having more onboard RAM in its sensor, allowing for faster processing and a larger buffer depth. A few other notable improvements include a more robust Live ND feature, with new graduated ND filters and improved autofocus and IBIS implementation. Those looking to upgrade from an older model will benefit from going with the OM-1 Mark II, but if you're on a tighter budget, you won't be disappointed by opting for the OM-1. The cameras are also similar enough that it isn't worth the upgrade if you own an OM-1.
