I've got the D-FA 50/2.8 and the Tamron SP 90/2.5, but find myself
wanting the D-FA 100. I haven't tried the 90/2.8 1:1, but I don't find
my 90 enough longer than my 77 to make it worth using it, rather than
just cropping the 77 in post production.

I got the 90 because there are a lot of times that I can't, or don't
want to, get close enough to make use of the 50's macro abilities. On
the other hand, there are a lot of times I use the 50 because there
isn't room to use the 90.

Do you already have a reasonably fast 50 or 100mm lens? I've seen some
really nice stuff done with the 100/2.8 as a normal (non macro) lens.

Both will cover a 24x36 sensor (FA), but are also optimized for
digital sensors (D-), hence the D-FA designation.
