Good for 24-105 f4 L or less
Works fine with very weak blurry effect on a 24-105 f4 L but using a higher focal we get pictures more blurry so be aware. AF doesnt work on a 70-300 F4 L but stabliizer does work which is a good thing.

2x Overall satisfactory.
Overall satisfactory.
Important:
1) C-AF 2XII TELEPLUS is compatible only for EF canon series lents NOT with EF-S Series lents.
2)Using C-AF 2XII TELEPLUS and canon EF-70-300mm zoom lent the imagine live a little bit color tone.
3) when you select 300mm maximum focal length form zoom module the autofocus not work fine.
I contacted VILTROX company and I asked them if an update firmware will be possible for this 2x multiplier.
That's all.
