But you have to understand that lens, specially its curved plane of focus (if that is the right way to say it).
Agree, the Fix lenses all the time better than Zoom. I tried almost all of them for Sony A format. But my big concern it's my work, I NEED zoom all the time, as I use 16-80 CZ for a57(a77). Plus other view on the problem, a complete set of Fix lenses for FF Sony cost way more $$$$ than 24-70 CZ. I hope Sony some day can make some good lens with focal site 24-100(120) in A format, but so far it's looks like unreal dream.
