D7000 Crop Factor.
It depends on the sensor size. Low-end DSLRs like the D3xxx series have a tad smaller sensor whose crop factor is something like 1.55.
Canon sensor is smaller with a 1.6 (1.61 to be precise) crop factor compared with 1.5 of Nikon (1.53 to be precise). So the Nikon sensor is 11% larger.
