Re: Canon Extenders II vs III

The 2X II is designed for version II of lenses . It is better on my 70-200 mk II than the 1.4 version one [ kind of grainy on 8 X 10 - OK on 4 X 6's .

I was told even the 70-200 mk II is to old to benefit from the 2 X III  . At that time they said the 2 X III MIGHT work on the new 100-400 II  , but they did not think it would even fit . They also said there were different versions of the 100-400 , but none would that any 1.4 or 2X without and extension tube and you would loose AF .
