If I may bare my ignorance again....
I understand the smaller imaging area of the DX format. When using a standard lens that projects an image larger than the sensor, you get an approximate 1.5x cropped magnification. So along comes lenses designed for DX format usage, that project a smaller image to match the sensor (as well as collomated to more parallel light to supposedly reduce distortion). Shouldn't a matched image and sensor when using a DX lens on a DX camera negate the magnification factor? (I did try to search for this answer, but came up empty...I know there's been numerous similar threads though)
