This is a wonderful lens and i am so happy i got it.
I needed to tweak the camera settings a little bit mainly because the lens is naturally contrasty. For example, the DA 40 limited gave true to life images straight out of the box(brilliant lens) without any customizing but that is a case of a Pentax lens matching a Pentax camera.
So my first few shots with the Tammy seemed to be too contrasty so i tweaked!
The lens is very sharp from wide open.
The bokeh it gives is just gorgeous in my opinion.
THE BOKEH IS IDENTICAL AT 2.8 AND 3.5
It hunts a bit in AF but i like to manually focus anyway and due to its 1:3 macro you need to concentrate on your manual focus because it is very fine and accurate!
The colour is wonderful and it performs well in low light.
I really like its tripod collar too
