Excerpt: Kenko repair ( Huntington Beach, Ca. ) told me to send my 2x in for a chip update, so my Canon 5d Mkiii would stop freezing up, when used with my Canon 300mm F/4 L. ( -- ) never called when he said he would, and unless I got him on the phone, I was left no knowing how long it would take to get it...
Excerpt: I use this with a Canon 200mm F2.8. It's a great option to get that extra reach without the high price tag of a longer lens.
It's good quality and so far extremely pleased with it's performance.
No cons to list at this time.
