OK. Is there ANY information of relevance within the test report section
of Photodo.com? If you discard everything that is "weighted" -- as the
weightings are hopelessly malformed -- then are the raw MTF graphs
themselves of value? 

And how come they've posted the Apo 100R twice, once with great
(graphed) performance at 2.8 and once with cruddy performance at 2.8?

Comments?
