But this one (which for once can not be mounted on a small sensor) never leaves my second housing! 26x1.6 = 38.4; we prefer 35mm but we will not chipopter ... The sharpness is excellent (and not "spike" pity and thank you for it), and above it is very discreet and does not attract attention. With a big zoom everyone watching you, but with this thing I feel that people believe that the goal is "back" or that there is a cap before: we can put under the nose of passers and they unsuspecting ... ;-)
It is also very light, which is not negligible. The focus is not super fast but for me it is not important (I focus once with a separate shutter button, so there is no research to focus each shot view but only when we change the subject or point of view, but for the pictures "surprise" is a fault).
Overall, good quality, good price, what more.
