Well the time is is here that I have to make a choice between the two 24 - 70 f/2.8's, but not only there It's also time to up grade computer systems as well, but these just a tad longer.

Putting aside the $ factor would it be fair to say that the two are that close it basically comes back to good technique.

I am also still considering the D610 but any lens I do buy must be FX & DX compatible.

I would like to get a couple of filters, CPL & variable ND grads but at this point have only seen ad's for Hoya & Kenko and am trying to find the threads previously posted on these and can't remember which series were considered preferable.

In reality though $'s will be a consideration. so sort of leaning to the Tamron for this reason and most other AP'ers seem to be more than happy with this lens
