Very Nice, and Useful Accessory 
overall, i like this teleconverter. I use this with the new sigma 70-200mm F2.8 II lens for Rebel XTi. the F-stop became 5.6 with teleconverter, but i get up to 400mm zoom, which makes quite a difference. While it's true that most of my pictures came out soft, but some pictures came out quite sharp- so it may just be me. there is some slight color distortion, but it's only more noticeable when you shoot macros.
i glad i got it. and it has allow me to extend my lens from 140-400mm, of which 200-400mm is a critical range for wildlife and sports.
Affordable and quality
I've used Canon lenses, Tamron and Sigma. All are fine products. For my money I have found that Sigma works well, without the high cost of Canon.
Currently, I'm using my extender with a Mark III and mainly my f2.8 70-200mm Sigma lense. I'm mainly shooting High School Football games with this combo & my Turbo 2x2. It's working out beautifully! I would highly suggest the Sigma line of lense, esp if you're on a budget.
