I do everything manually - apperture, shutter speed, focus... The only automatic bit is the camera reading the DX code off the film cartridges!
What settings I use obviously depends on the lighting conditions, but as I use ASA200 film then in the current spell of good weather I would be likely to use f5.6 ( partly cloudy ) or f8 ( full Sun ) and 1/500th, assuming a standard ¾ view with the Sun at 90°. With the Sun behind me, if the scene is particularly bright, then I'll either go up to f11 ot 1/1000th depending on the speed of the subject.
My primary setting is the shutter speed, once I have determined what shutter speed to use then I chose the apperture to match it.
And I have managed to get quite reasonable pictures in the tubes ( with the correct photo permit in place and when signed in as a visitor, I hasten to add!

) with f1.8 at 1/30th, hand held, believe it or not.
