You can also use a Wratten #25, which is only slightly lighter and (at
least in Europe) much easier to get than a #29. As a starting point, I'd
suggest ISO 50, metering through the filter.

Most Canon lenses have IR markings and I'll take your word about the Tamrons not having this info.  Perhaps call Tamron for help about focusing their lenses on your A2 for infrared film.  Also, remember that the infrared film sensors in your A2 will fog one set of sprockets so you will see a line on contact sheets that hits right up to the image area.

Of course you won't experience such fogging problems with Konica. :-)
The new MACO IR 820c (not available yet...) may also be a good film to
use with your EOS. At least the prototype wasn't fogged by my EOS 500N
(= US Rebel XS).
