I have just bought a Nikon D3300 to replace my Nikon D3100. Both came with a 18-55mm lens. My D3100 lens had A/M and VR on/off sliders on it.. The lens that came with the D3300 doesn't. Is that normal? EDIT: This YouTube unboxing video shows the lens with the A/M and VR on/off sliders. How much worse is my lens, that doesn't have them?
