Pardon me for the goodu question but, I still dun get the depth on view preview function.
I understand that wat it does is to allow me to see how much the apperture opens (i think). But except for making the viewfinder darker (for a smaller apperture) how does it allow me to gauge how much depth of field will appear in my shot?
I mean I can't really tell if the DOP is going to be shallower or deeper. What / how am I to use it effectively?
