If you're reading this, you have a Nikon D5100 or D3100 and have been thinking of getting the new 40mm macro lens. Nikon calls this the AF-S Micro Nikkor 40mm 1:2.8G. I have it and I couldn't do a lot of what I do without it. The kit lens that came with my D5100 and the 35mm 1.8 don't have the close focus range of this 40mm 2.8 macro / micro. With this lens, I'm able to take pictures of my subjects extremely close up with amazing focus. All my product photography is done with this lens. The pictures of my D5100 are taken with my Nikon S8100 point and shoot. The pics of the 40mm lens are taken with my 35mm f/1.8 lens on my D5100. All other pictures are taken with my D5100 with the 40mm f/2.8 Micro/Macro lens.
