1. Use an EOS camera body and stop down the EF 50mm f/1.8 to f/8.
* If you use an EOS 1000:
Attach the EF 50mm f/1.8 and set the picture-taking mode to Av and set the
aperture to f/8. Cover the lens with your hand so that the shutter speed is several
seconds. Then while pressing the shutter button completely, detach the lens.
2. Set the lens focus to infinity. (To make it easy to see the focusing points.)
