The problem with the 200/4 is not lack of optical sharpness, but 
vibration when used on a tripod with inadequate vibration supression. 
Gary did a lot of testing of the 200/4 with various bodies and lens 
supports, and the best of them are really quite good. B/B- wide open and 
at f/32 and all A through B+ at all other apertures is a mighty fine 
test result. In practical use hand held, it's no better or worse than 
any other similar length lens in vibration, as one's hands damp 
vibration. On a tripod, hold the camera and lens with both hands while 
pressing down gently, but firmly, and it is fine.

You don't perchance have the alkaline battery that is the same size and 
shape as the no longer available mercury battery? Or a smaller silver 
oxide battery with a ring to make it fit? Both will throw the meter way off.
