NOT an ad for Sony (but you can take it that way if you like :-) ).

Quoting: "  ... Roger Cicala [of US company "Lens Rentals") is a hard man
to impress. His team tests a lot of lenses, but the new Sony FE 135mm F1.8
GM is a cut above the rest. Literally, *all* the rest. Roger's verdict?
'This is the sharpest lens we've tested. Period'."

Note that in the comparison MTF charts against the Zeiss Batis 135,, f/1.8
it is sharper in the middle but it is outperformed by the Zeiss in the
corners

Perhaps useful to compare other lenses with.
