Coming late but let me add my 0.02..
zero image cameras are fitted with an exposure dial as an accessory which helps you determine quickly the exposure needed at f/138 while you meter the scene say at f/16 with your lightmeter .. simply adjust the dial with your meter's f-stop and exposure value at ISO 100 to get the equivalent exposure at f/138 - really handy..
plus Fuji Arcos 100 behaves as a wonderful film having very little reciprocity failure..
