Mirror Lockup on T-90 in Canon FD Mount Posted May 14, 1999 T/90 was not designed for such modification and it would be a formidable challenge. I doubt anyone at any earthly price will attempt such a job because of the special nature of the half silvered center center of the mirror, the way the light path works for spot metering and probably other technical considerations. A practical and even more useful idea is to buy a Canon F-1n body used as your mirror- lockup body. Or a working model of the Canon EF. Both of these Canon models,and the earlier FT series had simple to use mirror lockup with a flick of a lever,along with other good features, use all the FD lenses. These older camera bodies are plentiful on the used market and affordable, in the$ 200-300 range lately. For a few hundred more, consider a new F-IN body.
