Of course it works. You may just have to use f/.95 all the time. You can hit the local photo store and test drive a camera and compare the meter to it. I've done it from time to time and the sales person never objected but, I always bought a little something to compensate, even if a set of batteries, a filter and film. Last time I did it of course I ended up buying a Oly E-500 kit but, that's another story.
