In terms of speed performance, the 7D Mark II is a solid performer. Shutter lag, cycle times and burst speeds are all very good based on our lab tests, and the generous buffer depth is also very welcomed. However, autofocus performance was not a clear-cut improvement over the original 7D. With the new iTR AF (Intelligent Tracking and Recognition) feature, which utilizes color information, face detection and other info from the metering sensor, the 7D Mark II provides greater focus accuracy, however that does slow down sheer AF speed (and burst rate slightly, too). Nevertheless, even in single-shot AF mode, which doesn’t use the optional iTR mode, we found the AF lag speed to be slower than the 7D and 70D.
