Using Tav with fully manual lens

Reading up on Tav mode, it seems one sets the aperture / speed and Tav picks the ISO ?

Doesnt Tav mode at least need an A aperture lens, otherwise how does it know which ISO to pick in Tav, if you have to manually set aperture ?

At the moment i've been using AF.s on the switch, and M on the dial , for Snap in Focus with fully manual lenses. I'd like to try this Tav mode, but a bit unsure on the proper way to do this , or which lenses it works with

Correct. With a pre-A lens, you can choose between fully manual and aperture priority. You can see this by putting on the lens and switching through the modes; the information display will show that you are in Av mode even if you use the dial to select TAv.

I'll give up the idea of Tav then for the most part. I only have 1 ' A' lens , ( 50mm ) so could try it out, but Tav will be of limited use, it seems.
