Hi,
I was looking for a teleconverter to mount onto Sigma 150-500mm OS.
AF aside, any bro has any idea how these 2 teleconverter fare against each other?
Lots of shopkeeper emphasize that kenko loses out to sigma in terms of IQ. Please advise b4 I splurge extra on the Sigma teleconverter.
Thank you in advanced
