Is there any method which I can do it by myself to see what maximum sharpness I can get from that lens?

Besides using the lens at different apertures and thoroughly inspecting the results you mean?
Probably the easiest thing to do is to stop down 2-3 stops (but no more than f/8 on crop-1.6 and
f/11 on fullframe) and trust in the old rule, that lenses gain quality when stopped down.
Franky, I would't worry too much about it ... as already said, there are more important
factors that using the lens at the stop with maximum performance.
Just my 2cts ... Rainer
