Ive just stumbled upon an AGFA isolette II Apotar pronto in an antiques store for £5. after trawling and trawling the net looking for manuals i havent found one specifically for this camera. there are a few differences on it to the cameras i have found in the manuals so far. can anyone help with a manual or any tips on the depth of field ring and whether the scale on the focus ring is in m or ft? it says m on it but im not sure if thats for macro or not!!!
