Yes, if you want tests that are comparable within the whole test system.



I know you're interested in macro performance, but as Klaus already said, we simply cannot do these tests, mainly because we'd have to find someone who is able to produce a decent test chart. That chart would have to be 24x36mm in size (or maybe 48x72mm if you can lie with 1:2 MTF data) and printed at almost infinite resolution.
