Help, I'm new to this forum, I decided to join to get some help. I'm really frustrated and I know that I am doing something wrong...I recently purchased a Vivitar 85mm lens- 1.4, its a beautiful bright lens for portraits for the price and would be even more phenomenal if I can learn to control using it! Here's what I'm doing... my camera is set to "manual" mode, I'm anywhere from 1.4-3.5 F stop because I want great DOF. I'm shooting outdoors at 4-5pm (Summer) in a wide open field, lots of nice diffused light, no camera flash, no reflectors just me, the model and the camera....I'm also 5-6 feet away from her at times, I change my position a lot when shooting to get different angles. While focusing however, I'm not moving a bit, I focus on her face, compose the shot, look through my viewfinder and it looks amazing so I continue, when I get home and load the pics up on the computer they are all out of focus and I'm being disappointed! What went wrong? I'm in manual mode and the image looked clear as crystal through the viewfinder but obviously they are not. Please help me figure out what I'm doing wrong. Thanks so much!
