View Full Version : Still Confused

I've read the FAQ's and Stickies, but I'm still pretty confused on what purpose a 35mm adapter serves.

I've gathered that it decreases the DOF for more specific focusing, but does it affect the actual image quality at all to look more "movie-like?" Or does the fact that the focus is more "movie-like" give the impression that it's "movie-like?" My apologies in advance for an idiotic beginner's question.

When I shoot I borrow our church's DVX100B, and I use the 24p. (Planning on getting my own very soon.) Can anyone post a video of a DVX100B with a 35mm adapter?

Yup that's all.

This is a preliminary website with a small presentation film I did for a painter. DVX100 (original) and Redrock M12 with Nikon lenses 50/1,4 and 85/1,8. Almost everything handheld - takes some practice. However ONE scene of this film was done with DVX native lens...It's up to you to guess!

The DVX100B should yield better edge-to-edge sharpness due to the fact it will zoom closer to the groundglass of the M2 adapter.

nice stuff, my guess is the shot where she is frame right, standing in the bushes, or whatever that stuff is. edge to edge seemed too sharp. Nice looking footage though.

Thanks Papa - You're absolutely right! "The bushes" is a field of sunflowers...

Okay thanks guys. Besides an adapter, are there any other accessories/techniques that can make something appear more "movie-like" on a dvx100b?


And....what does the lens size have to do with the picture?

Forget the movie-like story, forget the historical meaning of shallower d.o.f. story and focus on this:
Video is 2D, but we see in 3D
A shallower depth of field helps our brain see depth where no depth is present.
Bluried things have a specific meaning for our brain: they are nearer or farther than the thing we are watching to. Our brain enjoys 3D things. A shallow d.o.f. helps the brain reconstruct a 3D space.

Well the FIELD of view is completely different (and depends on the lens added), and I believe this is also a MAJOR if not the biggest part of the movie look.

the 3D shape can also be done without a shallow depth of field. All you need is LIGHTING hehe. Lighting will create somewhat of a 3D'ed object where a 2D image exists. Create depth, texture, and so on with light. And yeah, shallow Depth of field is great too.

One of the elements added to the look is what I'd refer to as latitude compression. This changes with the adapter, and with ours, from CF1, CF2, and CF3. What you end up with is a foreground/background (out of focus) with as much of one stop of extra exposure room.
