I have both full frame (Canon 5D MIII) and 1.6 Crop Canon (7D MII). When I mount my Canon EF 70 - 200mm f/2.8 II lens on my Canon 5D MIII (full frame sensor) the range of focal lengths is from 70 - 200mm. However, when I mount the same lens on my (crop) 7D MII, the range changes to 102 - 320 mm. (1.6 x 70 and 1.6 x 200). Essentially,
it brings all objects closer by a factor of 1.6. There are more technical explanations, that I'm sure others will offer, but this is a simple answer.
Hope this helps.

I have seen this term, "crop mode", used several times in the last few days, I think usually in reference to Nikon D8XX. I understand full frame and crop sensor as defining the physical size of the sensor. I own Canons, I have nothing against Nikon, have even considered Nikon but then I'd have to buy new len$e$. I just don't understand what shooting in crop mode is. Will some one please explain?
