Canon's sports and action APS-C flagship with 8fps burst and professional build quality.
The Canon EOS 7D was launched in 2009 as Canon's first APS-C body designed specifically for action and sports photography. With an 18MP sensor, 8fps burst rate, and 19-point all-cross-type AF system, it offered performance previously reserved for full-frame professional bodies at a fraction of the price.
The 19-point all-cross-type AF system was Canon's best APS-C AF at the time, providing reliable tracking for birds in flight and sports. Burst rate of 8fps with a deep buffer makes it capable for extended action sequences. Dual DIGIC 4 processors handle the data throughput. The body is magnesium alloy with comprehensive weather sealing and a professional feel.
The 7D earned a devoted following among wildlife and sports photographers on a budget. It is criticised for high-ISO noise above ISO 3200 and the APS-C sensor's dynamic range limitations compared to later Nikon competition. The 7D Mark II succeeded it in 2014 with improved AF and higher burst rate.
Decent value used for action photography on a tight budget. Check shutter count which is rated for 150,000 actuations, test the AF system with moving subjects, and verify burst rate reaches 8fps. The magnesium body is durable but check for impact damage. The Mark II is a significant upgrade if budget allows.
