comment:Good at 2.8 and very sharp stopped down. Low CA and low distortion. Better bokeh than the 24-85. Better CA correction than the 28-135.
In low light conditions very good at 2.8 at all focal lengths. In bright
light softer (at 70mm).

Changed sharpness rating to 4.5 after a compare with the Tamron
SP 28-105 2.8
