Jane Bown is one of my favorite photographers. She commonly used an Olympus OM-1n with the Zuiko 85mm f/2 lens. I happen to have that exact setup, so I went Jane Bowning with a roll of HP5.
I'm no Jane Bown! As much as I love the viewfinder in the OM-1n, I could not seem to get a handle on focusing that lens. Nearly every frame was out of focus. To be fair, 85mm at f/2.0 or 2.8 doesn't leave much room for error, but still.
