Hey Paul -

I sent you a PM on two f/2 FD lenses that don't have a place in my kit any longer. From my own experience of returning to film and returning to the FD mount, I'd look for the following lenses to make your T90 shine:

FD 135mm f/2 - amazingly sharp, build in shade
FD 35mm f/2 - below is a link to a Flickr image I know came from this lens
FD 80-200mm f/4L - the B&W lizard is this lens
FD 300 f/4L

These range in the $200 to $450 pricing from reputable resellers. There's other FD Ls (24 / 50 / 85) that are running $1000+ even today nearly 30-years after the FD mount was discontinued. You might not need to focus so much on lenses as much as the quality of film you use. My T50 from '84 and the 50 f/1.8 kit lens it came with took the best photo I ever produced with this combo when shooting EKTAR 100 a few summers ago. The color image below is EKTAR and an F1-N and the B&W is an AE-1 and Fuji Neopan.
