Originally posted by derelict I am using this lens more and more and loving it. Question: where is this lens sharp/ where is its sweet spot? Also, where is it sharp while still delivering bokeh that removes distracting objects in the background. I use this at car shows/ meets and being able to get a sharp shot of an ornament or a dash cluster while blurring other things out is important to me.
Mine is sharp right from f/2.4, just getting sharper by stopping down. and it's peak is between f/4 and f/8
But it's bokeh is smooth until f/3.5!? and on to f/4 and further f/5.6 it's bokeh is sometimes funky!
All in all I don't choose aperture based on sharpness on this lens specially! so use the aperture suites the shot.
