Silly question, but I have to ask...

I just picked up another 2X TC for another macro lens that I have, so I started to think.. and here is where it gets silly... Can you stack a TC on another TC?

i guess it depends on how much degradation you want in your image, I have done it occasionally but the quality is really bad

yes you can but the resulting image loss, speed loss and limited depth of field may not be worth it. If you stack TCs, you multiply their powers, not add them. So if you stack a 1.4x and a 2x, you get a 2.8x, not a 3.4x TC. You add the aperture losses, which in this case will be 1 + 2 = 3 stops.
