fast is second only to sharp for worst defined word

What is speed booster? Also worth mention: A teleconverter will MAGNIFY lens abberations. A focal reducer DIMINISHES lens abberations. So, double benefit...

you can take half an image circle but you can't take double of it

fast light-gathering?!

in this case it's more like pouring a big-ass pot of water straight down into a water bottle with and without a funnel

what happens when you 2x teleconvert a fisheye?
>>
>>2759251
You basically get a wide angle that suffers from horrible barrel distortion but not enough to be called a fisheye.

It allows for faster shutter speeds.
