I think you put your finger on exactly what is WRONG with this thing, what is it? Nice web site but, what is it? Can you imagine spending lots of money on developing something and then starting the sales thing and STILL what is this thing? I guess we are dopes because we don

These “gizmos” (there are at least three I can think of) allow you to attach 35mm lenses to a video camera so you get the same depth of field as movie cameras. I have one and it is awesome.

[alex viarnes] “These “gizmos” (there are at least three I can think of) allow you to attach 35mm lenses to a video camera”

Which are the other two?

P+S technik and redrock micro are the two I know. P+S very expensive ( about $10K) and Redrockmicro M2 about $1K. I own the M2 and for the money is an incredible l product. A bit of a learning curve but woth the effort.

Actually, those gizmos look great in DV quality, and with the HVX(and those HDV cameras) it will look even better.

By “great,” I don’t mean to my eye, but I mean to 98% of viewers on 98% of TVs and ALL current delivery formats short of theatrical release(in which case, I’m guessing it looks “alright”).

Heres a link to more info on the cinemek:

The only reason i know this is because i wrote a similar post asking about Pro 35 adapters for HVX.

Interesting, now I know more about it. But, I still don;t know why it takes 2 AAA bateries? If it is just a lens attatchment that allows you to attach a lens, why the need for batteries?

From the FAQ:

“How does it work?
The G35 utilizes an INTERMEDIATE FOCUSING SCREEN, which is tuned specifically to minimize light loss. It works by passing you image through a 35mm lens and projecting it onto a VIBRATING screen.”

The batteries vibrate the Intermediate Focusing Screen.

This gizmo attatches a 35mm lens to the front of a video lens. Inbetween the 35mm lens and video lens is the Intermediate Focusing Screen(IFS). The 35mm lens projects an image onto the IFS (which acts as a focal plane) and the video camera records the image from the other side of the IFS. The IFS is made of a grounded glass and has to vibrate and/or rotate so the ground glass texture blurs away.

Theres probably a better way of explaining this but I am partially iliterate. hope it helps!

That explains it very well. Who’d a thunk. Where will technology take us!
It seems like printing an 8×10 from a 35mm neg through an enlarger as oppossed to making an 8X10 contact print from an 8×10 neg with out any enlarger lens optics. The difference here is you get the depth of field of your selected apature but I can’t help thinking there must be some clarity lost from video tapeing a ground glass rather than 3d reality. (I should say video “recording” as video “tapeing” is becomming a thing of the past) If you could remove the video camera lens then you’re just using the 35mm lens which is the best set up. Perhaps it is good enough that the human eye can’t see the difference.
Another thing is the minimum close focus distance on the viceo camera is about where they must have to locate the ground glass. This would be in the wide end too. Most optics aren’t at their optimum clarity at the end of their zoom range as the curved outer edges of the lens elements are being used. Still I suppose the ccd’s could be the limiting factor over the optics.
