Testing CS-mount lenses on the Panasonic GH2

As a new owner of a Panasonic GH2 Micro 4/3 camera, I have entered the experimental phase of lens gathering.

The large sensor still cameras that also offer video capability are now plentiful and there’s a resurgence in interest in older lenses from still cameras, film cameras, and even security cameras. My research showed that CS lenses use the same screw thread and size as C-mount lenses, but they were designed to be 5mm closer to the sensor. I wanted to see for myself what exactly that differences meant in terms of usability for the GH2. Continue reading “Testing CS-mount lenses on the Panasonic GH2”

Consumer Digital Still HD video shoutout.

If you can get a consumer camera that shoots HD for just a couple hundred bucks, why not load up on the cameras and get multiple angles of an event for next to no cost. img_6430w.jpgPlus, you can move them around easily, perch them in unusual places and you don’t need a half-dozen video camera operators. Sounds great, doesn’t it?

Well, the reality is that the rolling shutter CMOS image distortion in video cameras is just as prevalent in digital still cameras. You can easily see it when you bounce the camera up and down lightly, or pan the camera side to side. Things that you naturally do when you are recording video with the camera in your hands instead of on a tripod. These motions distort the image from what really exists in reality. Camera flashes are partially bad- partially illuminating multiple frames. When you play that back, it looks completely unnatural.

To quantify these CMOS distortions, I secured two brand new digital still cameras that shoot HD video and pitted them side by side in some critical tests and the results clearly demonstrate the difference between CMOS and CCD when it comes to capturing video that faithfully represents what happened.

WIP: Alaska Video / Camcorder Review

circle.jpgIt’s tough keeping a blog going when you are busy with projects and one of those projects takes you up one of the loneliest highways— the Dalton Highway, up to Prudhoe Bay / Deadhorse, Alaska, where the oil is pumped for the Alaska Pipeline.

I was re-shooting an episode of IEBA’s Alaska outdoor adventure series, Wilderness Adventures Off The Beaten Path and shooting it in HD. That’s full HD, not HDV.  But using two different high-end consumer camcorders and writing about it for Event DV magazine.
