This is a great lens, I use it for landscape photography and it give me like a soft painting effect and at the same time it has a lot of detail with a good IQ. I am in love with this lens. It is also very light and compact.
For some people the weaknes could be that is a f5.5, but for me it doesn't matter because I always use f8 or f11.
I never go out without having this lens in my back pack.
