But your assertion the combination is "slow" is right but with faster film (unless there you feel you ~must~ shoot ISO 100 or slower film), just doesn't hold water. I often used f/8 mirror lenses at air shows, dialing in the 1/2 stop compensation in the camera. Otherwise, mirror lenses must be used on tripods/monopds and with deep (2"+) lens hoods. - This message is from the Pentax-Discuss Mail List.
