1.5 converter with a 28-200mm zoom?

Trying to understand what I gain by adding a 1.5 converter to a 28-200mm
zoom lens on my Canon Pro1? 300mm?

Yes, but it probably will not auto-focus, due to low light levels from
f/stops lost.

of the converter. For example the Nikon TCs for the CPs are designed to
keep the same f stop.

I have yet to see a 28-200 that is acceptably sharp without a TC and I am
a user of TCs. A 1.5 would indeed put you in the three hundred mm area but
the Kenko Pro 300 is 120 dollars while the cheapest Canon 75-300 lens is
about 170 - and good enough to use a TC on.

Adding a 1.5 TC will get the op a 42-300mm focal length range with the TC
