For me it's darn near perfect. Focus is good enough for all except fast moving subjects, kids or pretty well any sport.
No biggie for me, I love the liberation of fixed focal length. The lens is a stunner, plenty sharp enough wide open. Super resistant to flare.
I only ever shoot jpeg with it, I find the results very acceptable, love the film simulation modes.
If I could only save one in a fire, this would be it.
It's very versatile, it doesn't scare people..
I love the Retro styling and the solid feel of it.
Am I sounding like a fan.....cos I am...
