Did the K3 fit in 5D without much effort? If so, I don't mind trying their B3 or E3.
From B&H literature: "The Nikon Type B3 Clear Matte IIa Focusing Screen is an interchangeable focusing screen compatible with the Nikon FM3A camera. This Matte/Fresnel screen features a 3mm circular clear rangefinder spot and a 12mm reference circle. Ideal for general use, and especially with lenses having small apertures."
Silentlight,
I should point out, that statement is in quotes because it's not from me. I copied the opinion of someone else, who HAD done the conversion, (possibly even someone on the FM forums) to my database. I just pasted all my current data on alternate screens, here, in case it would save someone else a little time.
