The 630/600 was the first EOS camera sold with different names in different markets (630 in Japan and USA, 600 in Europe) and the first available in multiple colors (the 630 in black or "metallic gray", the 600 only in "metallic gray"). All 630/600 models have faster autofocus with "focus prediction", 7 custom functions (including options for back-button focus and film leader out), 7 Programmed Image Control (PIC) modes and 5 frames per second film transport, an improvement from the 650's 3 fps.
