Picture changes from 4:3 to 3:4 format?
A number of times on my OM-10 and OM-5 the size of the picture shot at 4:3 changes to 3:4 and you get a small picture when viewed in the monitor. Can anyone explain why this happens? It doesn't happen to all the photographs and I haven't knowingly changed any settings to cause the changes. Once it happens I can't seem to change it back.
Thanks for your help.
