A couple days ago I shot a small group image for an organization with my new 50mm f/1.4 G. I only had time to set up one soft box, but it still gave me f/8. Then the problems started. How on earth do you use a new G lens' DOF scale to figure out what is in focus. I thought f/8 might give me the DOF I needed, but as it turned out, it was just short of sharp on the back two people. Unlike the AIS lenses, there is no color coding (well, there is no aperture ring). There are just some obscure tick marks. It would look a bit foolish to consult the manual with every lens I use. I think it's a defect in the design of these new lenses. I'm not asking a question so much as complaining, in order to see if others find this to be problematic. I don't think the client will notice, but I did. Thank goodness for Photoshop<g>.
