I was looking at this example http://www.lonelyspeck.com …or-milky-way-photography/
It looks like a longer exposure at 1.4 at night can produce a nice effect with the stars and fairly sharp (given the correct exposure)
I understand the concept of a narrow depth of a field to a degree. You take a picture of a dogs face from 5 feet and you get his nose.. you back up and refocus, you get his eyes, then back up, you get his face and slowly the background.. but I guess what I wasn't getting is that it's really not a narrow depth of field anymore when you fully back up. The sharpness and picture that was focused on the eyes is now the same sharpness and focus that is applied to entire portion of the landscape (given how far you have backed up)
So, if that is correct and given the lens is equally as sharp at 1.4 as it is in f8 in center/border/extreme corner (wishful thinking i know) wouldn't a landscape picture at 1.4 look exactly like a landscape picture at f8? (in terms of sharpness and clarity, not exposure)
I should have explained that better in my initial post.
