This lens features an apochromatic design and maintains the original lens’ quality throughout the zoom range from 80mm to 300mm focal length positions. When in use, the minimum focusing distance of 15.4″, and 5.5″ working distance, is retained.
Judging by the expected magnification ratio of 1:2 magnification in combination with the 18-300mm C, this magnifying glass seems to be relatively weak (1 diopter?), which also means that it should affect image quality only very mildly.
Of course, it can be used with any lens that sports a 72mm filter thread, but as any close-up filter, it is better matched to telephoto lenses. For instance, a maximum reproduction ratio of around 1.3:1 can be obtained by pairing it to the Sigma 150mm f/2.8 DG (OS) HSM Macro (1:1 natively).
