Agus,

What brand of CDs are you buying that have this "already grounded glass?" The two I have are clear, so I must frost them myself (man I hope I don't screw both up!). As for the support, I am hoping to get some long rectangular aluminum brackets that create a mount to both my camera and box (I plan to use lots of washers). We'll see what old Lowe's (a hardware store here in Texas) comes up with! The more the better...keep posting everyone!!!!

Clay

By "haze" I mean that the image has some crisp details that are obscured as if they're shot through a fog. I'm re-attempting my initial design today, using the Radio Shack motor instead. If increasing the disc's rotation doesn't help, I'll assume it's the ground glass that's causing my problem.

Agus -- what kind of motor are you using to spin your GG?

Well, that remains to be seen. I've already used one, and it's certainly quiet and stable, but it may not rotate at a high enough rate.

More to the point -- I've seen a lot of Agus's footage, but little of everyone else's. So I'm inclined to use Agus's design as the best point of reference.

DOF, lenses, etc...

I really want to build an Agus35 but before I do I want to get my info right, so please bear with me on this one.

Does the .7x wide angle converter (Century Optics) or the Achromatic Diopters (Century Optics) create depth of field to be used with the Agus35?

I'm not to keen about the physics of light and the lenses you guys are using. What lenses do you guys recommend to a novice like myself who doesn't know much about SLR lenses?

I want to do some close up work, like with the achromatic diopter mentioned above. What lenses would you guys recommend?

Is a eBay a good source to find these things? What about Ritz, or B&H Photo Video, etc.?

The interchangeability of lenses have been adressed before and I wanted to know all lenses were compatible with the F to C mount adapter mentioned in a post earlier. Thanks for your guys' help!! :]

Really Fine Sandpaper

You can find "Sanding Films" where they sell plastic models. They are made by Testors and the finest is REALLY fine. I used the next finest to start with then used the finest to finish. I started my adapter last nite and I will post some pics as it progresses.

Randy,

I had the same confusion with the wide angle adapters, but they are saying you need to get one that is wide angle and macro so that you can use the macro part, not the wide angle part. Go to ebay and type "wide angle macro ??mm", with the ?? being your thread size needed. That's where I got mine, and it was only $32. As for the SLR lens, get the best one you can. I would try to find a 50mm f1.8. The 50mm is the closest to what the eye sees. Remember, you want the best lens possible! Good Luck...

Clay

Danny,

The macro is for the video camera. You don't need the wide angle part. Here:

Camera - macro - spinning cd - fresnel - SLR lens

That's the order. If you are confused about mm, look at your video camera lens and there will be a number (37 for mine) with a circle and a line through it next to the number. This is the thread size for filters, extensions, wide angle and macro lenses to be added to the video camera. Hope that helps...

Clay
