Very simply put, the Minolta Maxxum 4 is a Maxxum 5 (tested February 2002) but with a few features missing-and others altered-in an identical camera body. Missing are a depth-of-field preview, the Minolta Eye-start system, which automatically activates the camera when it's held to your eye, and the ability to use various Minolta flashes at high speeds. Other changes are diminutions: a three-sensor AF system from seven, 1/2000-sec top speed and 1/90-sec X sync instead of 1/4000-sec with 1/125-sec X sync, a polycarbonate lensmount instead of metal (plastic lensmounts have worked well on all budget SLRs using them), 1.7 fps continuous film advance rather than 3 fps, and 12 custom features rather than 14. Missing functions? The Eye-start system, and the duration of the LED display in the viewfinder.
