Before getting any new lens it may be a good idea to buy the
Imatest software first and test the quality of the lenses
you already have and will get. Imatest is no longer cheap
though but may prove a good investment for any testing
including scanner resolution like I did with the demo version.

Erwin Puts thinks there are enough older lenses around that
can still perform as good as the latest ones. By cherry
picking (with Imatest) a bunch of secondhand FF lenses you
could still end with a top quality range. They may not have
all the bells and whistles of the new versions but that
shouldn't show in the images.

Then there are the lenses that perform in all the tests:
Sigma 70 mm f2.8 macro, the Tamron 28-75 mm f.2.8, the new
Sigma 50mm f1.4. The first two on many bodies. Of course FF
wide angles have been less in demand for some time and that
will change with 3 FF systems below 3K$.

Few sites with user lens reviews are as readable as
www.dyxum.com but that one is only for the Alpha mount.
