Not as good as the 27-70mm f4 L IS USM from Canon then either?

 

It would be surprising if was as good as the Canon f4 given that's 200g more and (more significantly) has a larger diameter. (assuming that Canon and Zony are about equally good at designing things with the current tech)

And it isn't: if DXO are to be believed, it performs on 24MP similarly to how the FE performs on 36.

 

But I don't want those extra grams on my bushwalking lens! The Zony is already at my upper limit for those purposes.

 

(but then I cut the ends of my toothbrush for multi day walks)
