use manual mode. thats what i do all the time.
F value should be higher if you are using a slower shutter. i
think for your case 1/40 and F11-13 should work.
I thought for KUB EDS best is to use shutter pirority? Then
you just set shutter somewhere between 1/40-1/50, and then the DSLR
will settle the rest of the settings.
