Will there be a rod support system available for this new adaptor?
It sure looks nice...
Jimi :)

The neutral density filter enables light in to be controlled without closing the iris on the front lens. It would be placed between the SLR camera lens and the gg. It makes it easier to control light without losing the creative depth of field effect of having the front lens aperture wide open.

Image path in my arrangement is :-

SLR lens >> Neutral density filter >> GG >> prism erector >> Achromatic dioptre >> camera.

Also, I chose to have the prism offset, down and to the left of the camera lens centre axis of the PD150. This places the centre of mass lower and makes it easier to use handheld. It also puts the noisy bits away from the camera mike if I use it.

Bob,
I think Quyen meant controlling the light using the camcorders iris, which would not affect the DOF effect.

Marco Mezzalana · December 13th, 2005, 03:35 AM

Many camcorders, as my 170, has built in Nd filter, so for example I can use it. I did some test in very bright location and I found 2 way:

1) if you want low DOF then you close the iris or use camera built in ND

2)if you want high DOF the you close the SLR iris.

Ok are not a huge discovery, but it could be useful to someone...

only problem is that if it's too bright (eg in a bright sunny day) then the image being projected on the GG could be blown out...

Wayne Kinney · December 13th, 2005, 05:23 AM

True,
Infact i think the P+S mini35 has its own iris, must be for the same purpose.

Michael Maier · December 13th, 2005, 02:03 PM

Looks nice Quyen. How much for this one?
I also remember you talking about an adapter with a relay lens for the HD100 and a HD adapter somewhere in the boards or in your site. When will those be ready?

Jeremy Edge · December 13th, 2005, 10:33 PM

Quyen,
I sent you an email.
The adapter looks to be very cool...any estimate on what this one will go for?

Andreas Rylander · December 14th, 2005, 09:01 AM

Wow!! =)

It seems you are a friggin' genius! :D

Can't wait to see your progression =)

Kyle, It looks as though the SLR aperture is being closed and opened, not the camcorders (or looking carefully, maybe a mixture of both), but the changing DOF you see is due to the aperture of the SLR lens, not the camcorders iris.

EDIT: On closer inspection of the clip, i think this is whats happening:

The SLR aperture closes, widening the DOF....then the camcorders iris is opened to make the image brighter, no change in DOF. The cam's iris is then closed again, no change in DOF....then the SLR aperture is opened again, shortening the DOF.

I assure you it's the camcorder's iris being opened and closed.
