Hi Guys,
In 'normal' SLR photography, there is a relationship between depth of field and aperture - the smaller the aperture, the bigger the DOF..... I was wondering whether the same applies in the wacky world of digital cameras and digiscoping.
You see, I have a bit of a problem (failing eyesight!!) in telling when the image in the little LCD screen is absolutely in sharp focus - and a little bit extra DOF might help a bit.
Of course, conventional wisdom is to have the lens wide open so as to allow as much light in and to try to allow as short a shutter speed as possible.
I'm thinking that if you had (for example) a choice of going with F4@1/1000th or F8@1/250th it might be worth sacrificing the shutter speed for a bit of extra DOF.
All this is a bit of a joke at the minute, since when I was peering out of my window earlier on today, I was looking at something like F3.8@1/8th!! .... but I am dreaming of those bright, sunny days in the summer!!
