Hi Based on my new experiences of using my Blad, I am seeking some focusing screen \ WLF tips. Mine has an Acute Matte D, which I gather was an improvement over the Acutte Matt types, but are famed for being a bit tricker to focus than the old fashioned ones? I find that if I just look down as normal into the chimney, I seem to be able to focus OK (my eyesight permitting, which needs glasses) - the shot looks nice in the viewfinder. I did notice that the view seems to "move" a little, in that the brightness\contrast\focus seems to dodge about if I move my eye around but I read http://photo.net/medium-format-photography-forum/00U9Xb?start=0 which states that the AMD screens have a sweet spot which one needs to get used to and try to utilise every time. True or false? More significantly, I get the view into what looks like focused, but when I pop up the little magnifyer, it isn't in focus, but then if I press my eye right up to the magnifyer to the point that my eye lashes are bent over it, I think it looks OK and I can fine tune it. Does that sound normal or should the magnified view match the higher WLF view? I read somewhere that the magnifyer can be adjusted for individual eye sight, a bit like viewfinders on the F5, but I haven't worked out how or if that can be done with mine? Any advice\guidance?
