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 ยต4/3rds 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.

Frankenstein Test Black and White
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.

cat-in-a-box channels greta garbo

So I'm sitting at my computer, when I start to notice a racket in back. I ignore it for a while until I hear a load "thump!", as if something had been dropped on the floor, followed by a lot of loud rattling. I turn around and see Lucy in the box just having a grand old time, rolling around and rattling that box a good one. I grab the GX1 and snap a few shots before she notices me and the camera, then leaps out and back into her chair (which used to be my chair before she decided it was her chair).

Just like caring for Katie my black Lab taught me about dogs, caring for Lucy is teaching me about cats. She finds me fascinating, as I do her. And she expresses great affection and love toward me without coaxing. I try to return the affection and love, but she is a cat, and she takes a bat at me on occasion, although I think that's just her being playful. She always has her claws in when she does that.

She sits next to me during the evening in her chair while I sit in mi…

first night for the gingersnaps

The first night has passed and the two have managed to survive, in spite of what their tiny hearts might have thought when first arriving. Greebo, the larger of the two, has been in hiding the entire time so far. Ponder has spent the time zipping in and out of hiding spots, checking things out, and learning just how comfortable pillows are for resting your head.

During the night I felt the tiny body of Ponder hitting the bed as he leaped up on the side, and then climbed to the top to run around on top of me. At least once he play-attacked my fingers. He might be small but his claws are still quite sharp.

When I got up in the morning the bowl of cat kitten food was fairly well depleted. It's been refilled and fresh water put in the big dish on the floor. I'm assuming that both Greebo and Ponder are feeding and drinking. I have seen Greebo under the furniture peeking out at me when I went looking for him. I'm leaving him alone while he continues to adjust.

So far the guys h…

vm networking problem fixed

Over the weekend I upgraded to Windows 8.1, then discovered that networking for the virtual machines wouldn't work. Then I tried something incredibly simple and fixed the problem.

Checking the system I noticed that three VMware Windows services weren't running; VMnetDHCP, VMUSBArbService, and VMwareNatService. VMware Player allows you to install, remove, or fix an existing installation. I chose to try fixing the installation, and that fixed the problem. The services were re-installed/restarted, and the virtual machines had networking again.

Once network connectivity was established there was exactly one updated file for Ubuntu 13.10, a data file. This underscores how solid and finished the release was this time. Every other version of every other Linux installation I've ever dealt with has always been succeeded by boatloads of updates after the initial installation. But not this time.

Everything is working properly on my notebook. All's right with the world.
