Very impressed with this lens. The in lens stabilization is very good. I took several shots inside our unlit church when it was almost dark with a 0.8 second exposure, with no obvious shake. The resolution is more than adequate over the whole range. See photo.

Great lens and a fantastic substitute for something like the sigma trio...only thing is that it’s not the sharpest lens around. Still produces some great shots, but there’s definitely some room for improvement on sharpness
