in the process of looking for an ultrazoom/travelzoom lens for my Canon M50 I am also looking for Tamron and Sigma EF/EF-S lenses with the EF/EF-M adapter.
Does the test for defining an optics module for Photolab mean, that you were able to use that lens on that camera, including autofocus?
I ask, because in the list on the “Supported cameras” part of the Photolab homepage (nearly) every candidate is listed.
Was a lens in the list of that camera tested with that type of camera:
It is totally clear, that in the end it is my risk to buy one, but the answer to compatibility is not always clear on other forums.
It would be good to know, that it was working at the time of the tests.
