Modern tele-converters are supposed to be real good and would have to be a lot cheaper, plus lighter. Just a thought...

Is the correction factor of 1.5 only applicable to the lenses that were on the old camera ? or is that EF lenses and should I be looking for EFS lenses to get the best results ?
What is the difference between EF & EFS lenses
