Formatting your SD card directly in the Olympus OM-1 keeps its filesystem exactly how the camera expects — here's where to find the menu option and what the OM-1's format actually does (and doesn't) erase.
The Olympus OM-1's two SD card slots can back up, split, or roll over automatically between cards — but the default Standard setting doesn't do what most people expect. Here's how each of the six slot modes actually behaves.
You can choose from among several options for the aspect ratio of photos on the Olympus OM-1. But there's a catch worth knowing about.
What does a 12-100mm zoom actually look like on a Micro Four Thirds body? These real-world sample images, shot on an Olympus OM-1, show the full range from 12mm to 100mm (a 24-200mm full-frame equivalent) in practical terms.
Faster isn't always better: the OM-1 and OM-1 Mark II don't need the priciest V90 cards to hit full burst performance. Here's the UHS speed class, capacity, and card picks that actually match what these cameras demand.
My name is David Coleman, and this is my site. I take photos for a living. Seven continents. Dozens of countries. Up mountains. Underwater. And a bunch of places in between. I'm based in Washington, D.C.
This site is where I post practical photography help, tips, and troubleshooting.
All posts and reviews on this site are written by me. And I only review gear with which I have personal hands-on experience. By a photographer, for photographers. More about me.
