As a non experianced F-3 s-log user i need help with shutter-mode-and speed, how can it be used properly. I work in EU, therefore 25p (50i)
All i know is:
1. in front-left of F3 shutter can be switched on and of
2 in menue camera shutter speed can be changed (1/50,1/100...and so on)
3 raise up shutter speed will reduce motion blur, fast moving objekt can be projected better. Exposure will be reduced (less light). Maybe iris has to be open, maybe a little gain


my questions are:
a. how will be worked with shutter properly, what shoul de used as standard, general shutter on oder of, which speed 1/100 (??)
b. becouse to keep depht of field i want to keep for example iris open at 2,1 or 2.8 (Zeiss CP.2 or Nikon 80-200). If there is to much light at location, i can use ND Filters. Can insted of using ND filters also shutter speed be raise up a little (1/50, 1/100). what is better, use ND early or start first a little bit with shutter-speed 1/50 or 1/100
c. if shutter speed will be raised does this have any issues to picture quality, does it change the general dyanmic range in s-log
d. for which objekt-movements should be used which shutterspeed. when will motion look unnatural becouse of too much shutter speed

Thanks for your help and explainations

Use the shutter,

Set it to 180deg or 1/50th of a second for the most traditional "film look". Correlates to 1/48th of a second that most film at 24fps is exposed at.

+1. This works very well to tame the motion blur if subjects are moving and not even quickly.
 
anyone know what the actual shutter off button on front of camera does when in fact you can still select time based or degree shutter from the menu? I am typically using 180 degree or 1/48th but that button on front has my mystified.
 
shutter off halves the 180 degree shutter speed. Thus at 24fps it is 1/24th sec and at 30fps its 1/30th. Many people use it in low light to get an extra stop. I rarely notice much blurring and never hesitate if I need the exposure.
 
I could be wrong I think that I read that it selects automatically the shutter speed according to the light source it detects. For example if you have a light that flickers at speeds other than 60htz it would set it to 1/60th.
I know for a fact that that feature exist but I'm not 100% sure that you selected by just no selecting any speed at all.
 
I'm sure there is a slight blur on rapid motion, but I've been shooting those speeds for years and never had an issue.
Star, do you shoot progressive? It may not make an exposure difference in interlace but it certainly does in progressive - gives you a full stop.

Douglas, are you sure that autosensing thing exists. Never heard of it before. Its not what shutter off is at any rate.
 
I am sure that I read it in the instructions. It is mainly used for flickering detection. I don't have a link to the instructions, but it should be easy to find on a pdf. I'll look for it.

Reducing FlickersTo reduce flickers, try either of the following two methods:
Setting the shutter speed according to the power-supply frequency
Activate the electronic shutter (page 49) and set the shutter speed according to the power supply frequency.
When the frequency is 50 Hz
Set the shutter speed to 1/50 or 1/100 seconds.
When the frequency is 60 Hz
Set the shutter speed to 1/60 or 1/120 seconds.
Using the Flicker-Reduction function
Set “Mode” of “Flicker Reduce” (page 112) of the CAMERA SET menu to “Auto” or “On” and set “Frequency” to the power-supply frequency (50 Hz or 60 Hz).
Note
If the frame rate selected for recording is close to the power-supply frequency, flicker may not be reduced sufficiently even if you activate the Flicker-Reduction function. In such cases, use the electronic shutter.
Recommended settings for flicker reduction
Frequency
Always set “Frequency” to the power-supply frequency value appropriate for the shooting area.
Mode
• It is recommended to set “Mode” to “Off” when shooting outdoors or under lighting that does not cause flicker. (It can be also “Auto,” but the compensation may not be done properly.)
• It is recommended to set “Mode” to “Auto” when shooting indoors or under various lighting that may cause flicker, such as fluorescent, sodium, or mercury-vapor lamps. (If continuously shooting under lighting that may cause flicker, “Mode” should be set to “On.”)
