Each has its own advantages and which one you choose to use is largely a matter of preference.
Canon 6d shutter speed increments.
A indicates iso auto.
Most digital cameras let you control shutter speed and aperture in 1 3 1 2 and full stop increments.
How do i set the iso speed eos 6d.
30 1 4000 sec 1 2 or 1 3 stop increments bulb total shutter speed range.
At the minimum for 24 25 30 fps or 1 60 sec.
Total shutter speed range.
Iso speed setting increments.
As indicated below the iso speed will be set automatically to suit the shooting mode.
25600 in 1 3 stop increments.
If the iso speed is set to a auto the actual iso speed to be set will be displayed when you press the shutter button halfway.
For example 125 indicates 1 125 sec also 0 5 indicates 0 5 sec and 15 is 15 sec if you see a after the number then interpret the value to be read as a function of seconds.
Or higher for 50 60 fps depending on the frame rate.
I set this to shutter speed aperture which lets my 6d change my selected aperture or shutter speed if needed to get a good exposure in the av or tv mode.
1 4000 to 30 sec x sync at 1 180 sec.
The shutter speed signal accumulation time is limited to 1 4000 sec.
Available range varies by shooting mode.
Shutter speed display the shutter speeds from 8000 to 4 indicate the denominator of the fractional shutter speed.
1 3 stop same here for iso.
If set to iso this lets the 6d change a manually set iso if needed to get a correct exposure in any of the auto exposure modes.
Available range varies by shooting mode.
Most cameras come with 1 3rd stop increments as the default setting and a very large number of photographers never stray from it.
I prefer 1 3 increments.
