I've got a few MF primes which I'm loving using on the E-pl1, now would like to get a zoom which I can use for video mainly. Looking for something around the 28-80 (old school) range. Doesn't have to be fast, but I would like it to be: Small and light. Not varifocal - would like to pre-focus zoomed in and be able to zoom out keeping focus. Easy to turn focus ring - small throw so I don't keep rocking the camera. Maybe push/pull zoom for same reason - might be smoother to use. I have the m14-42, 40-150, 14-54 Mark1 and 70-300 digital lenses, these are all pretty good as far as I can tell but just looking for something manual to try. BTW, I have Konica AR and M42 adapters ATM. Anyone using Manual zooms for video? What are your thoughts compared to digital lenses? Any recommendations of what to try and what to avoid??
