Hi All w/ camera advice my dad has an old Minolta camera..(dunoo anything about it except that it has a big lens(like about 6-7" long). Now can i use this camera to take Coil pics if i keep it far away?(like 15'?) will that protect it and all electronics? second question is that on the shutter button, there is a dial w/ A, a ton of numbers, and a B. Now is this how i set the Shutter time? if so, how do i do it? thanks, alan
