    We hear about legacy glass, why not legacy flash?

    Got this OM series T20 flashunit today ($10 including postage!) from an online auction.
    What a sweetie in very good condition for a 30 year old - human or otherwise!:biggrin:

    Fits nicely on top, takes two AA batteries and offers thyristor flash-based auto sensing to 5 metres @ f5.6 with 200 ISO. And came with original olympus leatherette pouch as well.

    I seem to recall reading that there can be a bit of a worry about the trigger voltages with older flash units being too high for modern digital cameras and potentially causing damage?

    I've seen a few people using the T20 on m4/3 cameras, so I assume it is okay. It is definitely worth doing some research before putting an old flash anywhere near a new camera.

    This is probably the best list of safe and unsafe legacy flashes out there: Photo Strobe Trigger Voltages

    It mostly discusses the use of legacy flashes on Canon EOS bodies, but as far as I know, the data also applies to other systems.

    Should be safe based on the list mentioned by stratokaster.
