First to review Pana100-400 &Oly300Pro+TC

Mathieu of Mirrorlessons has added the review of Pana 100-400. He had already reviewed Olympus 300 f4.0 pro +TC and looks like the first one to do the review of both the Superteles..

Having tested both lenses and also on both EM1 &GX8, his observations are of particular interest.. Here are the links for ready reference...

Of course, a direct comparison of images may not be possible as shooting conditions are different, but for those who are considering the two options, some useful insights can be certainly gathered from it..
