A Tale of Two Lenses

Canon TV C-16 21.6mm-129mm F2.7 Zoom

Canon TV C-16 21.6mm-129mm F2.7 Zoom

Since my Panasonic GH series cameras can be adapted to use just about any lens, I am always keeping an eye out at thrift stores for vintage 35mm still camera and16mm motion picture and TV lenses. Usually when you find a lens in a thrift store it is usually either overpriced, not very special, or is in poor condition. I was very pleasantly surprised when my wife found not one, but two interesting lenses in the same week at the same thrift store. Continue reading

DIY GoPro Jaybilizer Jib Arm Test

This is a test of a DIY jib arm design for small, light cameras like the GoPro Hero. the boom is a 12′ paint extension pole. I need to work on the trapeze so that it has less friction, but overall I can see this as a useful tool. I want to try my Samsung HZ10W next, as the GoPro is not the best video quality and the fisheye lens is so wide that you cannot avoid lens flares. Shot at 720 60p conformed to 24Fps. ungraded, edited as Prores in FCP, compressed with the Elgato Turbo H264HD.

GoPro on a Mic Boom

This is a test mounting the GoPro Hero HD on a microphone boom, with some care and a better boom operator, this might be a good solution for quick and dirty crane shots. Below zero temps outdoors made this a an indoor test. This was shot at 720P 60fps conformed to 24fps. Edited in FCP with no grading.
Note for animal lovers: All the trophy mounts were inherited from my Father-in-law.. I only shoot wildlife with cameras.

Jabilizer 3000 Canon 5Dmk2 problem

I’ve run into a problem with the Canon 5D Mk2 and the Jaybilizer camera stabilizer.
I had two customers that are using the 5D and had sent me good reports, However, I have found that they had to add significant ( 1.5 lbs) counterweights over the washers that are shipped with the Jaybilizer.
I was able to do some hands on testing today and need to share the results.
First is that I discovered that we need to under sling the counterweights to lower the center of gravity and to provide mechanical advantage for the weights. Otherwise the weight of the camera and stabilizer becomes unmanageable.

Please look carefully at the attached photographs and notice that I had to reverse the bottom 3 1/2″ screw so that is pointed downwards. I then added 4 large (2 1/2″ Dia. (62mm)) washers in addition to the ten of the 1 1/2″ ( 37mm) washers for a total weight of 14 Oz. or 400 grams.
I then mounted the “kickstand” beneath the counterweights and affixed it using the wing nut.
For side to side counterweight, I loosened the gimbal handle screw and moved the aluminum rod as far to the left as possible and added 9 – 1 1/2″ washers to the plastic knob screw.
Note that you will have to purchase the 4 or 5 large 2 1/2″ washers in addition to the 25- 1 1/2″ washers that ship with the Jaybilizer.
This is a temporary work around to allow you to shoot with the 5D. I’m working on engineering a more elegant solution and will ship current 5D/Jaybilizer owners the upgrade your Jaybilizer at no charge as soon as it is available.
In the meantime I am not recommending using the Jaybizer 3000 with the Canon 5Dmk2.

Panasonic GH1 Jaybilizer3000 torture test

Testing the GH1 on my DIY Merlin-type camera stabilizer (the Jaybilizer3000 )
This is kinda a worse case scenario, I was testing for rolling shutter with rapid side to side movement and to see how 24fps looked when moving quickly on a stabilizer also I wanted to see how smooth the camera was on the stabilizer. Obviously for real production footage I would have slowed down my motion to smooth out the 24p.

Jaybilizer 3000 Camera Stabilizer Shooting Techniques and Montage

I finally shot and edited this video that goes over some of the shooting techniques for the Jaybilizer 3000 , my homemade “Steadicam Merlin-type” camera stabilizer. The techniques include orbiting shots, tracking shots, low angle tracking shots, flying Shots and crane shots. I shot most of the video with a Canon HV30 on the Jaybilizer 3000 with some additional hand-held footage shot by Rob Martin with a Sony EX1.

Cheap DIY LCD Mirror Flip Shade hack for DOF adaptor

I demonstrate a DIY mirror LCD shade for the Canon HV30 to “flip” the image so that it appears upright when using a Jag35 DOF adapter. It should be noted that the mage is only corrected as far as being upright, the image is still “flipped” left to right. This can make panning difficult, but for static shots I find it an acceptable solution.
