Hello I recently bought an E-P1 and joined this forum today. I live in Edinburgh, Scotland.

Can anyone tell me exactly what settings I need to use when shooting with OM lenses? I'm aware that the camera can't autofocus the lens, so I have to be in MF. I read that some people people shoot in aperture priority, but how can the camera know the aperture? Do I just dial it in after setting the aperture on the lens? Is there anything else I need to be aware of?

Many thanks.

Welcome,
In A mode with a MF lens, the meter will set the shutter speed to equal proper exposure.
It doesn't really know what aperture is set but it knows how much light it's reading.

Brian Mosley has a few must view videos in the Oly forums.
Check them out and most of your questions will be answered.

So really the difference would not be in how the camera reads the shutter speed, but rather in how much light you get in the viewfinder, right? Whereas a digitally controlled aperture means the camera will always give you the wide-open view in your viewfinder (unless you press the DOF Preview button to manually stop down temporarily), then stop down before taking the photo... a manually stopped down lens will show a dimmer view in the viewfinder as you stop down, making focus a little tougher. Have I got that right?

The camera will bump up the signal so it will be brighter in the LCD/EVF for easier focus, but what you see is not what you get in the picture, at least on the panasonic side.

don't forget to set your focal length into the IS for it to work and switch on your histogram display when shooting to avoid blown highlights...

Do you set the focal length to what it is WITH the 2x multiplier or to the actual focal length of the lens. For instance when using a 50/1.8 OM do you set it to 50mm or 100mm?
