Olympus 2X-A Teleconverter doubles focal length for OM-mount glass.

The 2X-an is a purpose-built teleconverter for a specific set of Olympus OM-mount lenses: the 100mm f/2.8, 135mm f/2.8, 135mm f/3.5, 200mm f/4, and 200mm f/5. Pair it with any of those lenses and you double the effective focal length, getting 200mm reach from the 100mm or 400mm from the 200mm, all through manual focus. The compatibility list is tight by design, this converter was engineered for those specific optics, and that focused scope matters for optical quality.

For a film-era OM shooter who already owns one or more of those compatible lenses, the 2X-an extends a kit that was already paid for. Reach goes up without buying a longer prime. The manual focus operation fits right into OM-system shooting discipline, where deliberate, controlled technique is already part of the workflow. If you're building or maintaining an OM film kit and want more telephoto range without adding a separate long lens, this converter does exactly that.

Who It's For

Film photographers shooting with Olympus OM-system bodies get direct value here, specifically anyone who already owns the 100mm f/2.8, 135mm f/2.8, 135mm f/3.5, 200mm f/4, or 200mm f/5, since those are the confirmed compatible lenses. A wildlife or nature photographer working a film OM kit can push their 200mm into longer-reach territory. Portrait shooters with the 135mm who want occasional extra distance have a path there too. Manual focus discipline is required, which suits methodical shooters already comfortable with OM-system glass.

  • Compatible with five Olympus OM-mount prime lenses
  • Manual focus operation

FAQ

Which Olympus OM lenses work with the 2X-A?
The 2X-A is designed for five specific OM-mount lenses: 100mm f/2.8, 135mm f/2.8, 135mm f/3.5, 200mm f/4, and 200mm f/5. It won't mount on other OM glass or work reliably with lenses outside this list.
What focal lengths do I get when I use the 2X-A?
You double the focal length of the base lens. A 100mm becomes 200mm, a 135mm becomes 270mm, and a 200mm becomes 400mm.
Is the 2X-A an autofocus or manual focus converter?
It's manual focus only. There's no autofocus operation with the 2X-A.
Do I need to own the original OM lens to use this converter?
Yes, you need one of the five compatible lenses. The converter mounts between the camera and the lens and is designed only for that specific set of optics.
Will the 2X-A work on digital cameras with OM adapters?
The verified information covers use with OM-mount film cameras and the five compatible lenses. Behavior on adapted digital bodies is not documented.
Why is compatibility limited to just five lenses?
The 2X-A was engineered for those specific focal lengths and apertures. Tight compatibility ensures optical performance when used as intended.
