35mm adaptor?

It is used to attach 35mm still/video lenses to a video camera (usually with a fixed lense). The reason for doing this is to create the same Depth of Field as 35mm film.

Here is a good example:

it allows you to attach 35mm format lenses onto videocamera lenses. You can then capture the same depth of field on video that you would normally only get with a film camera.

Basically you have a SLR lens, like canon or nikon, or minolta that captures the light, focuses it onto a opaque surface. That image on the surface is then magnified, so that the video camera can record it.

To purchase, they range in price from $10,000 for the top of the line PS Tech

But there is a ton of information here and on dvinfo.net about how to build your own. Many have here and have had much success. I have built my own, but am waiting to post until I have shot a resolution chart (something that allot of makers seem to not care to post)

and why?-thats where the drawbacks to this adapter come in. Some, many of them the DIY kind, experience artifacts like abberation, weird colors, soft focus issues, distortions. These lenses and cameras werent made to work with eachother, so its difficult to fix these issues. But that said, the images some of these guys are creating are incredible
 
I assume it isn't possible to acheive that look just with the DVX-100AP? Hmm thats really kewl though, maybe I can find a used cheap one...
 
it is possible to get very close to this effect with just a plain DVX. Open your iris to a 2.8 and back your camera as far back from your subject as possible, the zoom in to compensate

ex: f2.8 and Z75 then set focus. Pain in the ass, but possible
 
While that gives the same feeling as the effect its not exactly the same - you always have to have a long focal length and therefore it is always a zoomed in shot so it will feel tight.

This is opposed to a 35mm effect - you can use a 50mm lens and still get the back out of focus - so it FEELS loose but the background is out of focus.

I have used this techniques with the DVX and while it "works" it is very limiting from an aesthetic standpoint.
