Kenko DGX 2x Teleplus Pro 300 with 60D

Canon is better [ if you are a really great photographer and crop a bunch ] , cost more and only fits a few lenses .

I went with canon , I need all the help I can . I do crop a lot sometimes- like a group of 8 people , I might crop out one face .

Canon 7 D , Epson 837 printer and 100 pack of costco 8.5 X 11 photo paper . I shoot raw + jpg .

I have various 1.4 , 2 and 3 X ones , but they are all at least 6 years old . The canon 2 X III is the best one I own .

If you can afford it get the canon III version , if not the canon II .
