I am back doing macro photography and have found myself struggling a bit focusing using the standard Type EC-B. Don't know if it is just me, I seem to be having some problems determining if the shot is really in focus; especially in the centre of the shot. Not sure if this is the reason but I am used to focusing on my F3HP and D2Hs. Both the cameras uses the split screen type of focusing screen. Now I am considering changing the focusing screen in the F5 and am looking at the Type A focusing screen. I am wondering would it help me in the focusing; or would another type of focusing screen would help more. Thanks!
