Jjc appears to sell two identical models of this tool. the other one has a review saying the ruler doesn't line up correctly. is that the case here?

Lines up correctly and used this to calibrate fine focus on a Nikon 70-200

Has this been used forna 70 - 200mm lens?

I used it on my Canon 70-200mm L series lens.
