Frankenstein Camera System

There are times when I fail to leave well enough alone. With a mix of older Olympus Zuiko bodies and lenses from the OM era, combined with regular 4/3rds bodies and lenses as well as µ4/3rds gear, I find I can mix and match up some very interesting combinations of bodies and lenses.

There will be a super moon tonight, and I wanted to play around a bit with trying to get a large clear image. So I've decided to shoot the moon tonight with an OM 4.5/300mm telephoto lens using an OM-1 adapter, mounted on an EC-14 teleconverter either on the E-3, or else, with an MMF-1 adapter, on the E-P2. The lens and EC-14 combination give me an equivalent 420mm 1:5.6 telephoto lens, which the 4/3rds sensor then multiplies to 840mm (or thereabouts, as the multiplier isn't quite 2x).

For testing purposes I chose to use an E-1 body in the back yard because it was lying next to me on my desk when I got this particular wild urge. I was looking to see what kind of detail the whole combination could resolve, which was why I trained it towards the screen. You can see the individual weavings as well as spots of dirt on the white paneling. Overall, I think this is pretty decent. I also think I need to replace the screening this year, but that's another issue.

Both of the images are from the same exposure taken of my screened-in back porch. I processed both in Lightroom 4.

For this set of images the 300mm was closed down to f/11. For the color image at top I pulled up shadows +30 and whites +50 to help pick up the detail a bit, especially the screen weaving. For the black and white I pulled the shadows in +50. While this impromptu experiment in the backyard was done on a ladder for support, tonight I'll use an official tripod. I'll also try this with the Zuiko Digital 50-200mm racked out to 200mm with the EC-14. This will give me an equivalent 280mm/560mm telephoto view.

I'm not so sure about the OM 300mm any more, as it shows tremendous purple fringing in high-contrast images all across the image. I'm waiting for the next release of Lightroom 4 because it's supposed to reduce purple fringing in software. If it doesn't work, I think I'll put the OM 300mm up for sale. But until then, here's hoping for good shooting tonight.
