My 135mm is a very sharp lens, but it still is much sharper at f4/f5.6 then at f2. If i take pictures at S:1/250 A:f4 ISO:100 they look sharper then when i take them at S:1/1000 A:f2 ISO:100.

Some of this may be focus error. You've got more DOF at f4 than f2.

Several photo related web-sites have useful widgets to compare lenses, and the same lens at different apertures. Dpreview, http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=769
