Has anyone with this lens noticed any back/front focusing issues when using it at 10mm.
Out of curiosity I did a few test shots using the 50D's micro adjust facility.
I took 3 shots, 1 at 0, 1 at -5 and 1 at -10.
To me it seemed as though the -10 was clearer than both the others.
Does that suggest my siggy is front focusing?
Whats the best way to do a dedicated test?
