There are mistakes people make when evaluating lenses. The easiest thing to measure is the extinction resolution, but that actually gives very little information about how the pictures will look like. You at least need to look at MTF50 to get some idea about sharpness. But it's still not enough. The maximum resolution doesn't necessary correlate with how sharp the pictures will look. I had some soft looking high resolution old manual lenses. A human eye is more sensitive to the lower spacial frequencies and contrast at those frequencies play a bigger role in perception of acuity.
