Neutral Density Filters and DoF...a question

Is there any comparison showing neutral density filters used to reduce the DoF on video?

I'm curious what can be achieved using filters as compared to a 35mm adapter. There are examples of these filters online but they are primarily all with 35mm still cameras and not video.

Is there any value in using these filters to allow a different aperture when compared to a 35mm adapters?
 
The more open the aperture...the less depth of field . It is less noticeable with smaller chips but it still applies.

Combining wide apertures and longer focal lengths will achieve DOF - but maybe not as much as you want in every situation.

I suggest to the O.P that you try using the in built NDs or attachment ND filters to saee how it works.
 
Ya...I was asking if there were any comparisons online to look at...I understand how it works.

I don't have a camera here with me right now, nor do I have any sort of attachable filters. I've seen the examples online but they all use 35mm digital cameras it seems so of course the lens plays into it. In addition to that, manufacturers love to exaggerate the effect by showing the image without the filter half size and with poor compression.

I assumed that someone somewhere has posted their results but I can't seem to Google any myself.
