I am thinking of purchasing a 2X TC for my Sigma 70-200 f2.8 but i have read the usual good and bad reviews mainly concerning loss of image quality but how much loss ??
I am aware of the f stops that are lost associated with it too.
The extra reach it offers is appealing but seems pointless if IQ is seriously affected.
A 1.4X seems to have little or no affect according to the reviews i have read and this seems more of an option as i don't want to buy a 2X if it aint going to perform.
Anyone here use either and what are your opinions please.
