I like the colours, I like the contrast and I like the sharpness. I can't fault this lens at all.
Remember, all these images were taken on the Nex-5N which is a fine camera. It might be different on the Nex-7 with it's 24MP sensor but I doubt it. I think I'll try it out one day but I tend to keep the 18-55 kit lens on that. I am also waiting on the 55-210 for that camera. I was disappointed by the colour shift you get with the Nex-7 with RF lenses but it's something we have to live with. The Nex-5N does a fine job though and I can't complain there either.
