Re: Is Canon EF-S 18-135 STM lens too soft in large apertures?

I have exactly the same situation as this. MFA has addressed some focusing issues, but undoubtably, the lens requires stopping down by a couple to get sharp results. i also find that using the centre point and adjusting the focus manually helps greatly ( although I think that this applies to most, if not all lenses). The results are there, as with everything, they need work.

Nothing of the foregoing discussion is surprising. It is, after all, a 7x+ Zoom lens,
