C100: Shooting question for c100 in changing light conditions

I'm just coming over from DSLR (5D III and 7D). Just wondering how you guys handle shooting situations with big swings in lighting. Do you set your iso at {850} and adjust in post? I am strictly shooting in-camera to SD card.

Thanks,

It's no different to your 5D, the 850 ISO people talk about is the cameras optimum setting for the widest dynamic range. I think the 5D is 320... I'm not 100 % on that though.

there is no such thing as the widest dynamic range in regard to ISO
 
for the most natural way of changing exposure while recording. you have to have a lens that has a manual aperture ring (for example, Samyang 14MM EF T3.1). This can fake a auto exposure. but other than that. I dont think so. anyone has better ways of doing so ?

There are several studies that would disagree, here's a table to look at.

If you take a look at the sensor on the 5D3, you can see that the dynamic range peaks at around 320.


It seems obvious to me that the amplification of the sensor and the introduction of noise would negatively effect the contrast ratio.


It also appears that it's not as simple as lowest ISO equals Widest DNR either, although high ISO's do indeed result in reducing dynamic range.
 
If you're shooting documentary style there's not too much you can do. Expose for your highlights, take advantage of the sun and practicals to try to shape the light the best you can. If it's a changing situation, try to expose to protect the brightest spot you see. And yes, play with the NDs and ISO of course. I like to stay with 850 as much a possible, but I'm not afraid to mess around with it to get a good picture to the eye in a run n gun situation. When I can setup and light, I'll light to 850.

The c100 does not act like a 5d.

Every Iso has the same DR. 850 just has the most even distribution of stops in the highlights and darks with the lowest signal to noise ratio.
 
Thanks for all the help guys. I have learned quite a bit in my first month with the camera. Having the ND's built in has really changed my style of shooting! So convenient compared to the 5dIII with fader ND.
 
Hi Paul. I've just moved to the c100 (m2) from always shooting on video cameras. I shoot for news and documentary, often alone. There's a lot to like but at this stage, unless I buy another lens which is compatible with the auto exposure/iris settings, is there no way to avoid jumps in lighting (whether apeture stop jumps or ISO jumps) when shooting run and gun? I'm so used to subtly adjusting the aperture mid-record that I took it for granted...now when the lighting situation changes I reach for the aperture dial (in a horrible place, I have a to say), move it a stop and ARGH! massive, obvious shift Do you find on this cam that run and gun, when the lighting shifts, you compensate more with ISO than with Aperture?
 
You can set the aperture dial and gain settings to use a "Fine" mode to make the jumps a bit smoother.
Still won't be smooth but will be a bit better than the normal 1/3 stop aperture setting for example.
