Hi I have a Nikon D750 with a 70-200mm f2.8 VRii lens and a 35mm f1.8G ED lens. I mostly shoot family portraits. I was thinking about switching to the Canon 5D Mark IV with a 24-70mm f/2.8L II USM Lens and a 70-200mm f/2.8L IS II USM Lens. Will there be a noticeable difference in image sharpness and color?
