This is a quick non-scientific comparison video of several lenses. I compared the kit Lumix 14-140 lens to the following:
Canon FD 28mm F2.8
Minolta 35-70mm F2.5
c-mount 35mm F1.8 CCTV
c-mount 25mm F1.2 CCTV
Canon c- mount 11-70mm TV
the c-mount lenses used the SLR Magic adapter.
The subject is a wine glass, lit with 5600K daylight LED light source and the room was lit with 2800K CFL lights. The camera was white balanced for day light.
The GH1 is using the Ptools firmware hack and was shooting 24FPS no pulldown 1080P at 40Mbs with a 1/50th sec. shutter.
Edited as ProRes 422 in FCP. Output to h.264 @400Kbs
A time lapse test with the Panasonic GH1 with kit lens shooting 1/1000sec shutter in shutter priority. F stop varied between 8 and 4.1. Some shutter “wow”. I’m thinking I should have shot f4.5 in manual. any advice is welcome. Next time , I want to compare using apeture priority. as long as the shutter speed doesn’t exceed the the interval time I should be okay.

A perfect spring morning. Warm temps with fragrant breezes.

If you’re reading this article you probably are aware that shooting HD video with DSLRs is all the rage among digital filmmakers. There are far more reasons to shoot this way than not, but one of the problems with DSLRs are their sound recording capabilities. THe Canon 5D Mk2, the Canon 7D and the Panasonic GH1 have external microphone inputs but unfortunately these use auto gain control and have no manual control over input levels. Also these cameras don’t have headphone monitoring. Read more…
Mea Cupla is a short film exercise for my sound design class at Front Range Community College. The dialog and action were totally improvised and the video was shot in a half hour (still enough to irritate some other teachers ) We were testing recording second system sound using a Marantz PMD661 digital recorder and a EV RE-15 microphone on a boom. I was also testing shooting with the Panasonic GH1 camera at 720p at 60fps, the project was edited in Final Cut Pro 6 with a 29.97fps timeline. I used 50% speed with no frame blending for the slow motion shots. And finally I want to demonstrated some running tracking shots with the Jaybilizer3000 DIY camera stabilizer. The entire video was shot with a Panasonic GH1 camera using available light at ISO 1600 on my Jaybilizer3000 DIY camera stabilizer

This is a 60 sec. PSA for the college I teach at. It promotes the use of hand sanitizer to prevent flu infection.
It was shot in one class period using an Canon HV30 camcorder. I also used a Jag35 DOF adapter for several shots and shot all but two shots using the Jaybilizer3000 camera stabilizer.
Post was in FCP I only used the three-way color corrector and vignetted shots to match the DOF footage.

I added a couple things to my DIY camera stabilizer.
Detail of the inexpensive Tripod head mounted on the camera stabilizer
First, I figured out how to mount a cheap tripod head as a camera mount. This gives me a much more precise control of the cameras front to back balance and it also significantly raises the center of gravity of the rig. Secondly, because of the raised center of gravity, I now have to use counter weights on the bottom of the arm. This gives me a little more control of the rig’s roll characteristics. I also optimized the weights for the Canon HV-30 so it takes a lot less time to balance out the rig now.
Overall the design is evolving and improving and as I practice a bit more my shooting technique is improving. I would like to get a more experienced Stedicam operator to take it out for a spin.
