I have read a few reviews on the EF 85 f1.2L and as I notice there are a few AP members who list this unit in their gear, I was wondering if anyone had a comment on these quotes:-

"The biggest downside to the original Canon EF 85mm f/1.2 L USM Lens was the very slow focusing speed. If you were shooting portraits, it didn't matter. But, a lens this fast begs to be used for indoor action sports."

And then there's this:-

" I've determined that this lens model will occasionally mis-focus completely. The lenses do not front focus or back focus consistently and mostly focus dead-on. But there is a random situation that delivers a completely out of focus shot."

Are the above comments typical of this lens? As one of Canon's most expensive "black" lenses I was a bit shocked to read these apparent shortcomings and thought some members might be able to confirm that these criticisms are correct?
