*istD and older lenses

[chibitul smecher]

Hi, I am not locked into any system, and I am considering a dSLR. I 
think -and here please correct me if I am wrong!!!- that *istD is the 
most compatible with older lenses. Canon  (10d) doed not work with FD 
lenses, and Nikon (D70) does not meter with manual linses. What about 
*istD? I understand that there are some limitations, but you could use 
manual lenses, right? althouhg the *istD is not quite cheap, I hope to 
save on glass on eBay. please advice. Thanks!
