Peter, why dont you make me an offer, and let see what i can do.

Zac Stein November 25th, 2003 12:32 AM

hey i would love to see how this thing works in great detail.. like a 3d plan or at least a proper schematic.

I would then build a version which is more compact and using ground glass not a plastic cd.

Could you please send me full details of dimensions and alike, and exactly what is needed.

My email is zac@mindfreeproductions.com

If i get one built, there is no reason i couldn't get more built after.

I use a dvx-100e.

Zac

ps. when you video the picture on your camera, does it come out upside down, and you have to flip in post?

Agus Casse November 25th, 2003 02:46 AM

Yeah, exactly, you get the picture upside/down, which it is a bitch to shoot, but you can correct it in post, today we shoot a xmas ad for a tv network with the adaptor, it worked prefectly, i will post some material when i get it edited...

i can get used to after a while, but still it is a bitch.... hehehe now... if i could get a pentaprism from a SLR camera, i could correct the image from the adaptor. just like the SLR camera...

I will make all plans in 3dsmax, with complete animations to download and step by step explanations and tips... remember.. this is a homemade version, something that you can make it fast and works 100% perfectly, from there you can improve it and therefore get better video (better ground glass, selective speed, correct image orientation...

A fast solution with the upside/down video is using a LCD monitor fliped out in the tripod, or the stabilizer... i will make some tests with my monitor soon as well.

Some sample... hey.. i was bored... :) -->>>

That looks GREAT! You are a hero!

Zac Stein November 25th, 2003 08:57 AM

just a question.

I have an old broken canon FD slr, if i removed the parts that run from the lens up to viewfinder, and blocked the light from other sections.....

well if i placed spinning ground glass at the end instead of the viewfinder ground glass... would that work... and then used say a diopater to magnify the image.... is that how the real mini-35 sort of works?

Zac

Agus Casse November 25th, 2003 02:05 PM

Yeah, give it a try... try first with a homemade ground glass... or the SLR camera ground glass... if it works, replace it with the spining one

Joe Ryan November 25th, 2003 04:33 PM

awesome
 
footage looks great, can't wait to see more. really looking forward to your tutorial agus, great job.

Sebastian Scherrer November 26th, 2003 05:10 AM

I second to that.
 
I'm very much looking forward to your tutorial. I'll try to mount it to a XL1.

What modification would it require if it was to be mounted directly- that is without the
16x removable lense- to the cam?

Anybody been experimenting on this?
As for the XL1, it'd be much more practical, as the adapter could be made fit with the lense mounting mechanism!

Agus Casse November 26th, 2003 11:34 AM

I couldnt tell, i use a TRV18... but actually you should be able to mount it everywhere.

Paul Bettner November 26th, 2003 01:43 PM

How did the ad shoot go Agus? Got any footage to share?

Richard Mellor November 26th, 2003 04:57 PM

agus thank you for all your hard work. looking forward to the
chance to build this great device . your footage is great , and our tiny dv camcorders , now have a chance to make some great images

Peter Sciretta November 27th, 2003 10:25 AM

I have been trying to make this work with a 35mm lens and I can't seem for the life of me to get a good image that is not croped. I zoom but my camera (pd150) can't keep the focus

Barry Green November 27th, 2003 02:07 PM

You'll likely need a close-focus diopter on the front of your lens.

John Gaspain November 27th, 2003 08:34 PM

man o man, I cant wait for this tutorial!

in the meantime what do you guys recommend for a Film Lens? 35mm ..50mm? Brand?

Agus Casse November 28th, 2003 01:22 AM

I will have the footage of the ad as soon as i finish it adding the 3d animation.

Thanks you all for the interest in this adapter, it is a great thing indeed... i have been working all this week, and the results have been superb so far. I want to make the better ground glass next week.


Peter Sciretta, i solve it using an magnifying glass from a wide conversion lens that i have, the first piece will manify the image without ruining it.

John Gaspain, my best advice would ask for photographer about it, but i found that 50mm lens doesnt actually make closer or farther the image, the 35mm will make it a little up wider, me for example i am using a 50mm minolta lens, but i want to try up 35mm... once you build the adaptor, try to find photographer that let you try some type of lens, then you choose which you preffer.
