How do the first generation EOS cameras like the 600 series or the 700/750/850 hold up today?
The 600 series (in chronological order, the 650, 620 and 600/630) was the first group of EOS film cameras that Canon built. As the EOS system was still in its infancy back in the late 1980s the product lineup wasn t quite as well-organized into consumer, midrange and pro lines. Canon s autofocus technology was also less refined than it is today. The 600 series cameras are thus quite interesting. Since they covered a wider range of marketing categories than modern EOS cameras they often contain desirable features available today only on high-end EOS models. For example, the 600 series cameras are very sturdily built – a diecast metal chassis with a plastic shell. Their shutters require no power to keep open, making them perfect for astrophotography and other long-exposure applications, they can be used with all types of high-speed infrared film and they support interchangeable viewfinder screens. The EOS 630 had a very high frame rate at 5fps and the 620 and 600/630 had illuminated top-
