Since I've shot with the same system for years, I've always assumed that hot shoes were pretty standard for a long time. I got a surprise last night when I tried my Voigtlander external 35 VF in the hot shoe of my G1. It won't slip in at all--fits all of my Canons though slightly loose in my G9. I was thinking in the terms of the EP-1 (not planning to buy it, but someone wondered about the other external VF available, so I tried it).
So-curiosity is now making me wonder why I can't fit it in the G1 hot shoe. And--if I decide to buy a 3rd party flash for the G1, like a Metz perhaps, would it fit?? Anyone else with a very tight hotshoe on their G1??
