A FF equivalent 24-70mm f824. If that is all you need, aperture-wise, I bet it is nice. And I bet it is sharper than my EF 35-70mm f3.5-4.5 at f8 (which weighs 230 grams)
Strange thing: 0.25x magnification across the entire focal length range. That means it focusses increasingly closer the wider you go (MFD which goes from 12cm to 23cm). Which can be a bit of a bother when shooting because you keep finding you can't focus when you change focal length framing, until you move back.

It's a 24-90 FF equivalent not 24-70.

Given the size I don't find it very interesting, especially compared to the Oly 12-40 f2.8 which is much brighter and 5mm shorter and about the same size (slightly longer and heavier).

If the 12-45 had been a bit longer like 12-60 then it could have been interesting.
