I shoot with a Nikon D-80 and have 2 lens. but just ordered the 50.. f/1.8 D. I am very amiature, I know my camera option/buttons pretty well now but am still learning. I will be doing some "newborn" portrait shoots here in the next few months and this is one reason I wanted this lens but when I see certain pictures taken with this lens I was wondering if the photographer is using it in like a MANUAL mode?? HEre is the example where once part of the pic is in FOCUS but another area isn't.......how is this achieved especially in pics where the closest part of the subect that is closest to camera is out of focus and the farthest spot is IN focus???
