In this video, I talk about the differences and similarities between Minolta XD5 and Minolta X570 (X500), both of which are very capable auto exposure aperture priority cameras made in the 70s and 80s.
Some key differences will make your purchase decision lean towards one or the other. I’d pick X-570 for AE lock, full aperture + linked shutter speed readout in the viewfinder, and a physical on/off switch with a beeping option.
I’d pick XD5 for a more compact camera body (though less ergonomic without molded grips), half metal construction for durability (bottom plate is metal, top plate is plastic), exposure compensation dial, shutter-priority auto exposure, and if you don’t want to worry about replacing the low-quality capacitor on bottom of X-570!
Both cameras have a bright, easy-to-focus viewfinder with 94% frame coverage, and will provide excellent exposure in auto mode and manual using the newer silicon blue cell light meter, which responds to changing light much faster than older CdS cells used in SLR bodies prior to mid-70s. Since both are fully electronic, always bring extra batteries when out on the shoot.
Cheers!
