the one thing that i have really missed,after going digital.was the eyecup,on my olympus om4ti,it keep out the stray light,and allowed me to concentrate on the viewfinder.but now after ordering the following Nikon parts
finder eyepiece for the fe-fm
DK-3rubber eyecup
dk-22 eyepiece adapter
not cheap, but at £42 including postage.it was worth every penny,and fits both my d200&d300 body's,and works a treat.
