Are the 1.4x and 2.0x Tamron-F AF PZ-AF Teleconverters the only ones
that work with the FA-DA screwdriver and SDM lenses?
The BBAR versions have better multi-coating than the non-BBAR ones,
The MC4 indicates multi-coating and the # of elements, MC7 for the 2x.
I just ran some limited tests with my 1.4x (non-BBAR) and by golly, it
does focus the SMC lenses. But there is a loss of AF speed, probably
due to the loss of light factor. And of course the screwdriver ones
work as well. I originally got the set because they would work with my
FA power zoom lenses, as well as my Tamron 300 ƒ2.8.
