NO it does not! Changing the sensor size does not change the laws of physics. A 35 is a 35 no matter which body you put it on. The sensor size just adjusts how much of the image that the lens produces, gets used. It is a crop factor..ie it is the similar to cropping in tighter on the image.
( note for the techno geeks ( like me) I said similar, not the same, there are some differences in DOF and edge distortion but for 99% of shooters these don't matter, and I don't think they are important in this conversation)
