I think your right, Im shooting far to open.


Maybee being to lazy and hopeing the open lens will compensate for the quality of light or lack of it.





I think I have being shooting open all the time as this lens really does do wonders in poor light, I need to use the camera a little more and you guys have really confirmed I need to be more pro-active and not rely on the lens doing all the work.





I will how ever do some tests perhaps with a ruler just to gauge my lens. :-)
