Like many photographers in the Olympus / OM System world, I’m in the process of upgrading my photography gear from the E-M1III to the OM-1. Fortunately, SmallRig just started shipping a camera cage for the OM-1, since their long-unavailable cage for the E-M1II (which also fit the E-M1III) does *not* fit the OM-1. Before I sell off the old cage, I thought it might be helpful to compare the two models for anybody that may be in the market for one or the other.
At a high level, there are some key changes: some mounting points went away, or moved; the overall shape changed just slightly (in the process, access to body-front buttons is improved); and the new cage has a built-in Arca-Swiss mounting plate and captive attachment tool.
Back in February, I preordered one of the new OlympusOM System OM-1 camera bodies, and after a few weeks of waiting, it arrived at my local camera store. There are plenty offullreviews of the camera available for your perusal online, so I won’t attempt to compete with / duplicate them.
Just the same, I’ve spent a few weeks traveling with the OM-1 (using it daily), and I’ve got some thoughts:
Edited 3/28/2020 to add measured power data for both battery charging and tethered shooting.
Olympus, to their credit, has finally been replacing their old proprietary USB camera cable interfaces with USB-C on more-recent OM-D camera bodies. But until the E-M1X was released in early 2019, this just provided a data interface — for things like firmware updates, and file transfers.
With the E-M1X, Olympus began to use USB-C as a power interface as well — for battery recharging, and for tethered power supply to the camera. Olympus took a middle ground with the E-M5III, using USB for data and battery charging (but not tethered power, and even then using an old-school micro-USB connector). More-recently, the E-M1III followed the E-M1X‘s example in using USB-C for data, battery charging, and tethered power supply.
I’ve recently seen confused exchanges online about the uses and limitations of USB-C with the E-M1III — so as a card-carrying geek, I thought I should attempt to clear things up a bit. But first, you’ll need some background — so find yourself a comfortable seat and a warm beverage, this won’t be a fast read. Continue reading →
