Olympus OM system close-up and macro equipment

Canon digital replacements for Olympus OM 35 mm cameras

None of the digital system cameras have a macro system that approaches the one that was available for the Olympus OM 35 mm SLRs, and so there is considerable interest in making the old Olympus equipment work with a modern, digital SLR or mirrorless body.

Adapters that allow normal lenses to focus to infinity are available for various SLR and mirrorless systems. Canon EOS digital SLRs have become the most popular bodies to use as OM replacements for close-ups, macro and photomicrography, because of their sensor sizes and ability to reduce or eliminate vibration.

None of the early digital SLRs had viewfinders and focusing screens that were well-suited for use with macro equipment or microscopes, but models from 2007 onwards have introduced features that are proving useful, including:

Live ViewProvides real-time preview on the LCD screen that can be magnified to aid focusing.
Articulated LCD screenMore convenient viewing with the camera low down, or pointing down on a microscope or a copy stand.
Remote Live ViewMakes the Live View image available on a computer to check focus, white balance and exposure, and allows the camera to be operated from the computer.
Silent modeSignificantly reduces vibration when used with Live View. The mirror is already up and the mechanical shutter is already open, and an electronic first shutter curtain (EFSC) removes the need for any mechanical action when the exposure starts.
Full frame sensorMakes full use of the 36×24 mm image produced by OM lenses, instead of cropping to APS-C (22.2×14.8 mm) or Four Thirds (17.3×13.0 mm)

The ideal digital SLR for macro photography (and for photography through a microscope) would have all of these features, and be affordable. These are the Canon models that have been available up to early 2023:

** The 3-digit (e.g. EOS 600D) and 4-digit (e.g. EOS 1200D) Canon EOS camera do not have a selectable silent mode, but this feature is included and is permanently on when Live View is selected. More information from Charles Krebs and Canon USA.

*** The Canon EOS 60D and 80D have been reported to have a vibration problem in silent mode.

Most of the Olympus equipment can be fitted to a Canon EOS or Olympus E-series body using readily-available adapters. One exception is the Auto Bellows, because the long release lever on the camera body mount hits the protruding pentaprism on the EOS and E-series bodies. For the EOS 40D and 600D, this problem can be fixed by using a 14 mm extension tube, while the EOS 5D Mk II needs only a 7 mm tube. Most Olympus E-series bodies also need a 7 mm extension tube when used with the Auto Bellows, although the E-1, E-300 and E-330 do not need a tube.

Compact system cameras

Several manufacturers have produced digital cameras that are not SLRs but do have interchangeable lenses. Most of them have shallow bodies that allow Olympus OM lenses to be mounted and to focus to infinity, but most of them have sensors even smaller than APS-C. Canon make EOS M series mirrorless cameras with APS-C sensors, but has made them incompatible with remote use with EOS Utility. The newer EOS R series mirrorless cameras have full-frame or APS-C sensors and allow remote image capture with EOS Utility 3.
