Maybe i want to ask you guys something, what shutter speed is
good to capture the EDS?
For Coolair(eg. K230s) ones, you definitely need 1/40 to 1/60
shutter speed to capture full EDS. During sunlight shots, your
Aperture value might range up to 12 to 14, if not your photo will
be over exposed.
For Transit Media(eg. Dennis Trident) ones, you need
1/200 to 1/250 shutter speed. Aperture value would range between 6
to 8 depending how much you set for shutter speed.
