So when I was in Detroit last week, I took the chance to swing by a local photo shop in Dearborn. Didn't find any of the fancier vintage lenses I was looking for, but they did have a Tamron 70-210 58A in the $5 bargain bin; it's remarkably small/light for a 70-210, so I thought I'd give it a try for use on the fp.
The first test shots had some surprisingly good images, despite what appears to be coating damage in the center of the front element:

See the fabric texture on the artificial flowers!

Or the bug crawling on the real flower! (The antennae are clearly visible at 100%, which ain't too shabby.)

Bokeh is decent but not spectacular; I like its big brother the Tamron 80-210 (103A) better there.

Contrast is often low but is easily boosted.
On the whole, I'm pleased with the first outing. Not my top zoom in this range - I still prefer either the 103A or the Kiron 80-200/4.5 Macro for IQ - but for the size/weight and especially the price, I'm happy and will probably be using it more.
