However, in the 60's into the 70's quite a few photojournalists liked the Spotmatic for its lesser size and weight, and the quality of the Takumar lenses. Lens changes were not a big deal to a lot of them, because in fast happening situations there was seldom time to change lenses anyway. Usually, two or three bodies were carried, with a wide angle, short tele and normal lens used. One of the best known I can think of offhand, was Charles Moore, who took many of the pictures of the civil rights demonstrations and persecution of the demonstrators, and had close access to King and others in the movement. Minolta also had adherents, the best known of which was probably W. Eugene Smith. His Minimata work was taken with SR-T 101's.
Canon FT's, SR-T's, Spotmatics, and others were used by a lot of people who were more than "casual users".
