I purchased a low price macro lens filter kit to try out. The set came with +1,+2,+4,+10 magnification lenses. I used the screw on lenses with my Nikon D500 and a 70-300mm lens. Part of the focusing issue came from the lack of vibration reduction in my 70-300mm lens. It was hard to stay still. I took a few with my new Nikon 18-200 VR lens on its own without the magnifying lens for comparison.
