I bought Sigma 28-70 f2.8 DG DN for my ZV-E1 and I was shocked to find that the digital stabilisation doesn't work with this lens. Even the IBIS goes crazy when you turn on active or dynamic active with sensor traveling from one extreme to the other for no reason. The walking video has the image go up and down like I was on a boat. It's strange as the stabilisation works with all Sony and Tamron lenses I have tested. Moreover both digital modes work perfectly well when stabilising image from vintage manual lenses. Can you confirm that you have the same probelm with video Stabilisation as I have described? Sony customer service was not interested and Sigma didn't even bother to reply to my email. 😢
