Photodo is/was no joke. It was run with Hasselblad personnel and that company´s MTF equipment - I suppose the company did not approve of it in the end. The English magazine Practical Photography used their results a lot one time, though. But not knowing how they weighted the results adds a measure of uncertainty. But some of the much debated Photodo results like: which is best, the Pentax 28-200 of the original Tamron version of same, were verified by other tests - the Tamron is better. All the best!
