With great selection of scenes, the lens certainly shines like any other lens. When the circumstance is not ideal for wide open shots, you would be careful with neutral/harsh bokeh and occasional erractic auto-exposure. Sigma 30mm f1.4 does hunt its autofocus in medium to low light environment as Dennis has mentioned previously. To me, it is not as bad as my other primes like fa 43 or 31 ltd.
I sold my sigma 30/1.4 because it was for my canon mount APC camera before. otherwise, this is a lens I go for because it is well built, less boutique as limiteds and I can allow myself to be less careful with lens handling.
Definitely no concern with sharpness in the center. Before I bought this lens, the reviews on line had all sorts of MTF readings which are not helpful to translate these findings into real life images. I find images quite pleasant regardless what the testing parameters are like.
