I'm using my Sony NEX5N w Tamron 60mm via alpha adaptor. I'm pretty happy with the result for portrait purpose mostly.
But at f2, are there any other techniques to achieve even more background blur other than the obvious swap to a faster lense?
Reason I ask is because at the same f2 aperture, some of my pictures' background seem to have more blur than others... So wondering if other settings can affect this aspect of photography?
