Ok, tomorrow i will try to open a new post, explaing from a scratch how to build it, and showing diferent examples...

PLEASE everyone that have built the adapter, PLEASE SEND THE PICTURES that you have post in here, or new ones so i can also use them as example of diferent versions...

Thanks Again for the support of this adapter, and prepare because maybe after new year, the comercial version will be out.

Sounds great. Any ideas about the price?

Hello all. ........I'm not a genius when it comes to cameras and that sort of thing. If fact, I'm not a genius at all. ........anyway ....Agus .....I dont understand how you are focusing on the projected image, with the lens of the camera so close. ....(2 or 3 inches?) .........Seems like it would have to be at least 7 or 8 inches away before you could start to focus? .....Can you explain how you are achieving the focus at such a close proximity?

thanks,

chris

Chris -- you need a macro adapter, which allows your camera to get focus at objects less than an inch or two away from your lens.

Agus is using a wide-angle/macro adapter built for the small, 1-chip Sony cams - it goes for about $35 off of eBay, I think. The unit is two pieces - a small macro attachment that sits behind a wide-angle attachment - they screw apart, giving you access to the macros function. Depending on the size of your cam, the adapter is threaded for 37mm, and you may need a step-up ring.

If you have a GL1/GL2 or another camera with 58mm threading, Century Optics makes macro adapters going for $210.

Well isn't there a macro mode on the GL2? If you simply zoom all the way out and focus manually? Would that work?

Aaron Koolen · December 9th, 2003, 06:50 PM

No, I doubt the Gl2 could focus anywhere near that close - my XM2 can't....Just build a long adapter ;)

Hey, i drew a diagram of how I THINK it is built like. agus, plz let us know if it is correct. and i also have 1 question, how are you keep the entire thing connected to the camera lense? doesn't it fall off?

The GL2 does in fact have a superb built-in macro mode. Take off the lens hood, zoom out all the way to full wide. As long as there's enough light, the auto focus will pull in objects tack-sharp right to the surface of the glass. I've shown this feature to people many times, and it works great!

Aaron Koolen · December 9th, 2003, 08:36 PM

Chris, that's good to know. I usually focus manually, and have had all manner of troubles focusing close (i.e. just wouldn't happen) On my ladyx couldn't get closer than about 30 cm to one subject I was shooting. I'll experiment some more

Peter Sciretta · December 9th, 2003, 09:50 PM

would that telephoto lens support be long enough for say a pd150 or gl1????

Mike Bridgman · December 9th, 2003, 11:03 PM

Couple questions...

I'm curious if anyone has tried this with a DV953 yet? I think I'm going to tackle the project this weekend.

Also, I've been searching ebay for a 35mm lens to buy, and got lost in the hundreds of options...what are some good lenses for the Agus35 setup?

Agus this is definately the coolest thing ever...thanks man! ;)

Dale Anthony Smith · December 9th, 2003, 11:53 PM

Instead of ground glass or sandblasting or the like... what about using some FROSTED MILAR film. I've used it for shooting rear projected slides and as a diffuser for shooting HD from 4X5 transparencies. for the thin film I sandwiched it between glass or just taped it to one side of a glass sheet. You might be able to go with a plastic that's thicker and avoid the glass altogether.... Just a thought

This won't work with the Agus35, though, as you need to zoom in on the suspended picture (not out), and you're not going to have a lot of light at your disposal. Which leads me to...

You want to get the fastest lens around, which for a reasonable price would be a f/1.4. There are new, faster lenses - a new f/1.2 runs for about $560 new, half that used, but f/1.4's go for about $120.

Incidently, Canon makes an f/1 that goes for $2,600!

Re: the frosted mylar - where can we get some?

Stewart McDonald · December 10th, 2003, 08:59 AM

Would an f/1.8 lens do?

About the focussing using Gl2, how about if you brought the projected image closer to the lens so you don't have to zoom in on it? You can then manually focus whilst in macro mode to focus the image?
