Title: ND filter and related workarounds
Post by: Anton2707 on July 04, 2012, 10:45:55 PM
It would be nice to have audio control. Noise filter is the same as in Canon menu?
I do not want to create a new topic, ask here.
Is it possible to make a very low ISO (under 50)?

Try it. Probably won't work.  Iso 80 can happen in movie mode. Maybe drop more than .3 ev and see what happens.

In movie mode i can go to 25ISO silent pics (not sure if real, it's darker than at 100 but i've made just a quick test).

I know that, but image quality is bad and white balance too...
A low ISO get a quality built-in camera vari ND, normal white balance and focusing...

I'd just record a movie and average all the frames, like this:

A single frame from the movie:
