Minolta's 1999 entry AF SLR — A-mount, 30s-1/2000 shutter, GN12 flash; aka Maxxum QTsi.
The Dynax 303si was an entry-level autofocus 35mm SLR introduced by Minolta in 1999, sold as the Maxxum QTsi in North America and the α-360si in Japan. It sat at the bottom of the Dynax range as a lightweight, fully automated body for Minolta's A-type autofocus lens mount.
Its electronically controlled vertical focal-plane shutter runs from 30 seconds to 1/2000 with 1/90 flash sync. Program exposure includes five subject modes — portrait, landscape, close-up, sport and night portrait — metered by a silicon cell over a 4-20 EV range. DX film coding is read from ISO 25 to 5000, film transport is motorised at up to 1 fps with automatic rewind, and the built-in GN12 flash offers red-eye reduction plus an AF illuminator. Power comes from two CR2 cells.
It suits beginners and students wanting a cheap gateway into the large Minolta/Sony A-mount lens catalogue; exposure control is built around program modes rather than manual settings, so enthusiasts wanting direct control should look further up the Dynax line.
Used bodies are inexpensive and plentiful. Check that the CR2-powered electronics fire the shutter, the pop-up flash charges, and the film door, rewind and LCD all work; mirror and screen dust are common but cheap bodies make holding out for a clean example easy.
