if you don´t want old posts to pop up at the top... why not just close them after some time?
otherwise i don´t see a reason for such a reply.

Do you understand that the OP was asking for help last August??
 
 
Do you think that answering now is going to help him??

I didn't get a good answer the last go round... so maybe (as I'm the OP).  Having said that, I did find the answer. 
Upgrade  path.->means the former was sold for the latter.

In all honesty, the quickest and relatively cheap way to answer that question is to buy Reikan FoCal, and run your lenses through the Aperture test. It will take a series of shots at each aperture, measure them (I believe it just does an L/PH evaluation, but it might be something more like SQF), and plot the results on a chart. At the end, it will strait up tell you which aperture produces the best quality on YOUR GEAR. :)

What I found is that the 100mm I have is a really nice lens... so I can shoot at 2.8 or 8, and I will be more than happy with the results.  I think that is partly why I'm not willing to part with my 50mm f/1.4... because I'd much rather have a lens that is sharp with good results at any aperture rather than having to always stop down the 50 to f/2.8 to get decent results.
