Discovering the Canon 6D

With a 20.2-megapixel full-frame CMOS sensor and a DIGIC 5+ image processor, the 6D promised excellent performance, especially in low-light conditions.

The continuous shooting speed of 4.5 frames per second felt sluggish when compared to the more advanced models, making it challenging to capture fast-moving subjects.
