Thank you everyone for your replies.

They seem to be level in IQ, or, at least the 150 matches the 135 in IQ.

MTF graphs in fact indicate the EF-M wins in sharpness on both the wide and telephoto ends. It doesn't match it, it bests it. Go figure.

It just doesn't go to f/5.6 on the long end... f/6.3 is a very small sacrifice for another 15mm of reach and a much smaller, sharper lens.

Graphs are not always right, especially when you take it consider manufacturing tolerances.

Eyes, on the other hand, generally tend to tell the real story, and having both these lenses i cant see how anyone can say the 18-150 can match, let alone beat the 18-135 in sharpness.

Both are nice lenses, I’m not denying that, but only those that have both can really give a true indication.

Probably copy variation coming into play here Dave. My experience has been the opposite of yours, I felt the 18-150 was the better lens especially at the image borders. So maybe your 18-135 is better than your 18-150 and vice versa for me. So I agree graphs don't tell the whole story,they only tell you the story for the particular lens that was tested .

Actually (Canon) MTF is based on the theoretical lens performance.  It isn't measured performance.  But you are both right in that production variation can account for real-world differences.  FWIW I really like(d) both of those lenses.  The 18-150 is sitting on my M6ii right now.
