    There isn't an integral meter, so there's no ASA dial on the body - it's on the prism finder (if you've got one and it's a metered prism).

    There should be a filter thread on the 80mm lens. I don't know the size, but on my 70mm/2.8 it's 58mm.

    Take some time to study the loading path for the roll film. There's a diagram on the insert as a guide (I missed that first time and got a blank film!)

    Watch out for depth of field - 80mm on 645 has a field of view similar to around 55mm on 35mm but the same depth of field as 80mm on anything. This applies to all focal lengths and is a MF drawback with wideangles.

    Also be aware that the shutter release lock just locks the button - a cable release will still fire the shutter (BTDTGTTS!).
