So, the market they're targeting with this lens seems to be people who will probably be used to lenses where the zoom ring is toward the end of the lens. Then again, perhapsthe design was constrained bythe floating element rear-focusing system, requiring the MF ring to be physically close to those elements.

That was one of the things that raised a red flag for me in the article. Marketing usualy paints a picture that is carefully worded to point the consumer in the right direction without down playing the product. The comment didn't give warm fuzzy feelings because this comment could have easly said the lens is best for cameras at the price point of the 60D or 7D. The article seemed to down play the lens.


I thought that this lens might be marketed to those who bought the non L version of the 70-300 f/4-5.6 IS and are looking to make the move up to L glass.


I find the size of this lens interesting, smaller and lighterthan the 100-400L and the 70-200L f/2.8 it would be alot more protable. But in the end with me it has to have the IQ and until we see some reveiws we are just speculating.
