Which one?
I read and responded to your earlier one, and will be happy to respond to this one:

In one pair of tests, yes.
But as I mentioned in response to your earlier comment,
the same two lenses each received 3.5
as the corresponding subjective numbers in another pair of tests.
Originally posted by jac Forget about the platform or even the lenses themselves. A lack of objectivity becomes apparent to me.
The rating system is certainly subjective.
The tests themselves generally seem to be objective, just reading off from Imatest,
although there may be some subjective input in deciding to repeat tests,
or to choose one particular test image out of a series.
To interpret the tests (e.g. as a potential buyer of a particular lens),
you do need to consider the platform on which the lens was tested.
I would not regard the tests as "scientific,"
since they generally involve just one sample,
and do not seem to be reproducible.
