Hi Bill, all: this is a wonderful macro lens; it's the one I kept after buying a couple of others and keeping the one I liked best. I bought the Elicar 90/2.5, the SMC-M 100/4 macro (actually, this one was it's equal, but I felt i could sell this one for more money than the Vivitar......) No lens resolution line pairs per millimeter test stuff, I just took some pictures of my orchids on equal terms for all the lenses and judged the vivitar the best, especially at the middle apertures.
