setting the ISO when filming in full HD

Hi all

I am the very proud owner of a K5. The first digital SLR I have bough since I bought the first IstD when it came out. I am very happy with it. I am however about to embark on some filming for a music video and am interested in any tricks and tips when shooting Full HD on the camera.

Specifically, how can I set the ISO myself?

I have various 'M' lenses, like the 55mm F1.8 and Tokina 17mm F3.5, 'A' lenses like the 35-70 F4, and a couple of later zooms like the Tamron 28-75 F2.8.

So far I have found I can use the manual aperture only when the camera is filming when using lenses set on manual.

I have sussed out I can set my Auto ISO parameter rating in the menu, say 400-800, or 200-200. Does this remain when I change to film mode? There seems to be so little info out there, apart from the lack of compression when compared to a 7D (a good thing).

Congratulations for your decision...

As far as I know you cant set ISO-range manually for video, it will always be 100-6400.. fixing the aperture is your only choice, and the aperture is not changeable during recording, unless you use a lens with an aperture ring..

That's what I thought Michael, which is a shame. So far i have learned to point the camera at a bright source to lower the ISO then flick to AE-L and use the aperture ring. This seems ok, though it might work better if I take away the pin that keeps the aperture open. This is a trick I have seen people do when using Pentax fit lenses of 5Ds. What I want to do is set the ISO really low, like between 100 and 400 to reduce grain, and shoot on my fast lenses.

Any more tips?
