Recently, Alphatron released firmware version 0.5 for their Alphatron EVF electronic viewfinder.
This update can be a bit tricky since there are no on-screen cues to notify you when the firmware update is completed, instead you must rely on the LED status indicator of your USB key.
Watch my video above for a quick step-by-step tutorial on updating your Alphatron, and download the latest firmware from directly from Alphatron.
