I did some testing with my em5 ii and noticed the ibis is smoother with naitve lenses vs MF lenses. I tested the panny 25 and Nocticron vs Nokton 25 in video mode. I noticed using both AF lenses with contacts is significantly smoother vs the 25 Nokton during recording in video mode. No testing for pix. Is that normal for MF lenses? I was hoping/'thinking they would all be the same. And yes I did adjust the fl. Am I missing something or is this to be expected?
