Sony 28-135mm f/4 OSS - shall I test it ?
The voigt 15 III can be used on an A7 series camera with a VME or similar close focus adapter, so it'll easily be filled by the test chart.


But this reminds us of a problem with most rigorous published tests: they are at really very close focussing distances, and lenses perform differently at different distances.


And with wide angles, the kind of compositions you focus close for are unlikely to include any corner detail (which is what reviewers are often interested in). Corner detail is more common when you are focussing at longer distances or even infinity. But it's hard to devise a test for that which is rigorous (although an informal test is not hard)
