Couldn't wait to get some snaps taken with the EOS 40 D body a Camera Club Lady gave me as Not Working ( see 'Technical Troubleshooting Thread' ) So I tried a CANON Speedlite 540EZ on it and got bad OVER -Exposure and the TTL metering did not seem to work at all so I fitted the much OLDER CANON Speedlite 199A for FILM Canons and set 'Manual' shutter speed so set 1/250th on the EOS 40D and f11 aperture with MANUAL MODE and a bouncer onto the flash head and the close - ups of my Wife's Xmas Tree things came out well - so I am now a Happy Bunny using another FREE CANON !
Typical of old cameras and lenses, sometimess youneed to find a bit of a work around to get the best out of them.
