Thanks. Yes it also effects focal length. Nikon's crop sensors are generally 1.5 times crop and Canon's 1.6 if I'm not mistaken. Therefore when using a lens on a crop sensor it is multiplied by that amount. Say your using a 10-20mm lens on a Nikon crop sensor. It turns into a 15-30mm. I'm including a crappy diagram I just drew up at work lol. The circle represents the lens image circle and the rectangle represents the sensor. Assume your using the same lens on both cameras. The larger sensor is capturing a wider shot using the same lens at the same focal length.
