Is it me or is there just a surplus of these up for sale? I remember a few months back these were not up for sale often but not every other minute I see one up for sale .. an abundance of all of the different type from IS to Non and 2.8 - f/4.
Is it because of the rumors or because of the season we are on?
Also, being that I mostly going to be using it in the studio should I just get the F/4 vices the F/2.8 or should I just spend the extra $$ and get the F/2.8 for those occasions that I will take it outdoors?

?
