I'm on the list of those waiting the delivery of a Wanderlust Travelwide camera. There is a note on their site that says "Designed for the Schneider Angulon 90mm ƒ/6.8" but you can use other 90s. I like the small size of the Schneider so I went ahead and found an Angulon 90 on ebay in a Compur #0 shutter. I don't like the fact that the shutter speeds are marked as 1, 2, 5, 10, 25, 50...etc instead of the usual 1, 2, 4, 8, 15, 30...etc. I found a f5.6 Copal #0 shutter. My question is, does it make a difference that the shutter starts on 5.6 instead of 6.8? Can I simply not open it up further than the 1/3 stop after the 5.6. I've seen f6.8 shutters that only have two 1/3 stops between 6.8 and 8, which leads me to believe that the first 1/3 stop mark after the 5.6 mark is the same as 6.8. Are there size differences I'm not taking into consideration?
