I have both versions of the 90mm 2.5.

My oldest version has a little less CA than the second version. At least the first version has an internal floating lens group for better correction at macro and portrait distance.

Another very good and compact mf tamron lens is the adaptall 135mm 2.5.

Take a look at http://www.adaptall-2.org for a description and some resolution tests for tamron adaptall and SP mf lenses.

Gr.
