You will find the sorry tale and answer to your question here:
Your FD lenses will still produce excellent film images on your T70 though.
If you are used to shooting at 28 and 50mm on film, then you should consider the Canon 17-40mm f/4L or Sigma 18-50 f/2.8 - you have to allow for the crop factor narrowing your angle of view. The Canon EF 50mm f/1.8 is cheap but very good: on a crop body it's a suitable length for portrait work (same FoV as 80mm on film). Primes to research include the Tokina 17mm f/3.5, Sigma 20mm f/1.8, and Sigma 30mm f/1.4.
