Sorry to those who were expecting to see a field test of the Sigma Art 18-35mm f/1.8 with the Lumix G85, but looking at my clips, they only confirm what I already knew about the lens – that it really, genuinely is tack sharp from wide open with the Metabones Speed Booster XL – and I really have little interest in pursuing further tests of the lens. For the time being at least, I’m liking the results I’m seeing with native m43 lenses, preferring their compactness. If time permits, I’ll go ahead and post a video of the Sigma, as well as field tests of the Leica 12mm f/1.4, Tokina 11-16mm f/2.8 and Voigtlander 17.5mm f/0.95. I just received new LED video lights, so I’m more interested in shooting with those and sharing my findings than in doing lens tests at the moment. Incidentally, this was shot handheld and I shake like a mad dog, yet the in-body stabilization of the G85 was able to iron out the wobbles, so I see no justification for purchasing a Panasonic lens over any other brand based solely on dual IBIS.
