I have a question for any owners of the Oly 75mm, regarding the focus ring: Does the lens allow you to do slow, even focus pulls? I own a PL 15 & 25mm, and when shooting video I can achieve a nice slow and smooth focus pull when waned, however I also own a Panasonic 42.5 (not the PL), and its focus ring behaves completely different. It's very difficult to achieve a slow focus pull with that lens, as when you slowly rotate the focus ring, it doesn't move the focus position very much. It's not until you rotate the focus ring quicker that you can really move the focus throughout the range of the lens. So, to any Olympus 75mm owners, does it behave more like the two PL lenses I mention, or more like the new Panasonic 42.5 with regards to pulling focus? Thank you for your help!
