Today I experimented with an old 135/3.5 Olympus OM tele on the
E-510. It's like using a 270mm lens on a 35mm camera. Manual focus, manual
stop-down, aperture priority metering, and in-body image stabilization. I
focused wide open, then counted clicks down f/8 to shoot.
This is the best shot from today, a natural abstract with a crow and some
electrical wires:

Behind this typical childhood scene is a weird optical effect. Out of focus
highlight disks are greenish donuts surrounding a reddish core. Here's a
1:1 crop showing the effect more clearly. See the highlights on the
woman's glasses, bolts and washers on the bench, and cris-crosses on the
fence behind.

A couple more scenes from the park with the 135:

Focusing is difficult. If I keep using this lens, or my 100/2.8, I'm going
to want a focus confirmation chip on the lens adapter, and/or a Katz Eye
screen. Anyone with experience with either of these--how well do they work?
