Don't need to retest the lenses

This a comment for this page on the website
In spite of the quality of images each lens renders, which is undeniably good and not too far from each other in terms of quality, the mk II isn't parfocal which makes it very questionable for the sorts/genres of photography one would conventionally expect a 70-200 2.8 IS to be used in. Manual zoom/focus adjusting becomes slow and unwieldy, and in AF the AF mechanism is going to be like a heart beating twice as fast as it should be. My 2c, fwiw.
