Yesterday we are trying to do a interview shooting
so we are trying to use depth of field

but it is really hard to do so ..

one expert said take off the wide angle for vx2100

DVX100 what should we do

depth of field -- DVX100 vs VX2100

which one is better

We have both this machine
 
If you want shallow depth of field on the DVX, open up the iris, zoom all the way in, and use the ND filters if need be. Keep the background as far away from the subject as possible.
 
The chips in the DVX (and the VX2100) are not large enough to allow for great DOF. To cheat it, you have to move the camera back and zoom in. Also, try to light so that you can have the iris all the way open, even if that means using the ND filters.
 
Thanks

Thanks

That mean this 2 machine is still not pro enough to do DOF
----------------

That means I open the whole iris and on the ND ..
Thanks

what about VX2100 .. is it the same..

take off the wide angle .. do this make any point

DVX100 and VX2100 .. which one is more suitable to shoot interview

which cam is best for DOF ( please recomend or there is some filter )

I'm not sure that "pro" and "DOF" are necessarily synonymous.

And the DVX can "do DOF"... it has a pretty wide DOF, in fact. It just cannot get a very shallow DOF (which is what you're after) as easily as other cameras. Is there a reason you absolutely must shoot with a shallow DOF? The use of shallow depth is not the mark of a pro. In fact, heavy use of shallow depth can be just as amateur as having a camera that cannot shoot shallow at all.

Only turn the ND on if it's required to get the correct exposure with the iris all the way open. Under good lighting conditions, yes, you will need the ND. But if you open the iris all the way and have good exposure without ND, then don't use the ND.

Any camera with chips that are smaller than 1/2" (2/3" is even better) will have challenges in getting shallow DOF. Again, the trick is to have the iris open, and to move the camera back so that zooming all the way in creates the desired frame line.

There are 35mm adapters that allow for the use of 35mm lenses, which can help achieve shallow DOF. Those adapters, however, are not always cheap and take lots of care and attention in order to see that the results are usable.
 
ur dvx has 3 ccd's...each of which is 1/3 inch in size. the Larger the chip (ccd) the easier it is to achieve shallow DOF. the dvx has very small chips. Camera's with 1/2 ich and 2/3 inch chips achieve a shallow DOF easier.

As the others have said. Take off any wide angle adapter u have on any of the cameras. Open ur iris all the way, move ur camera as far back as u can and zoom in. Use ur internal ND filter and if u need more ND get an external one, to control ur exposure. Also separate the subject from the background as much as u can.
 
A Sony ex1 is the cheapest camera with a 1/2 sensor. Even that cannot give you too muh shallow depth of field. You need like a 7d or something. And that is a completely different animal.
 
i have had both cameras and ive noticed that the dvx100 has better DOF. it can just get way smaller where as the vx2100 is still good just not as close as the dvx100, but this may just because of the way i look at it, because they are both 3CCD with the same thickness in chips @ 1/3''.
 
What kind of lens connect?
A wide angle adapter "connected" to the DVX will result in deep DOF (more in focus).

I shot these interviews on the DVX with the stock lens- opened the iris all the way, zoomed in almost all the way with the camera across the room, adjusted my lighting to the open iris.
I think it's not super shallow DOF, but medium shallow, how I like it.

Here's something I uses frequently to have some DoF :

I crank my shutter speed a little bit. By cranking up, less lights comes in the cam forcing me to open the Iris. If I got lots of light sources, I used the ND filters to open the Iris even more. If I can get back my camera a little to be able to zoom-in I'll do it. The problem is the sound, your going away from your source sound. If you got a Mic it should be no problem.

I play a lot with those settings with my DVX100 to play with the DoF.

Try that!
