Did a small test here just to show. Camera on tripod on focusing rail. Camera was set at 1.1 ratio everything set on manual. VR off. Limit switch set at full. All focusing done by moving the camera in on focusing rail. Without touching any settings on camera 1.) First pic without filter. 2.) Second pic with filter had to move camera in exactly by 2" inches to focus. Did it magnify? No. Did it move the camera in closer? Yes. I had to prove this to myself. Enjoy
