Recently, my wife (mostly) and I have been shooting some basic event videos (single camera location, some zoom/pan across the stage, etc) on my E-M10 + O14-42IIR. The quality is generally good enough for the purpose they are being used for, but zooming smoothly with the 14-42 has proved to be somewhat of a challenge. And I have concluded that the thin zoom ring may be one of reasons for the jerky zooming (tried the 14-150 and it looks better). As the next one of these events comes up in about a month, I thought I would canvas some thoughts on a better zoom option. Ideally, starting at 12mm would be a good thing given some of the locations. As I see it, my choices are: Olympus 12-50: cheap, has a power zoom, people seem to think that its IQ is a little meh, but the images in the Showcase look pretty good to me. Can be had used for around $100 or a little more. Panasonic 12-60/3.5-5.6: Can be found around $200. May make sense if I get more into video and decide to get a Panasonic body with 4k. Is there any meaningful IQ improvement over the 12-50 here? Bite the bullet, spend $400-500 and pick up a 12-35/12-40PRO. Does the improvement in IQ matter for video? Would appreciate input from people on the choices above? Also, am I right in blaming the zoom ring? Are there any techniques which might help with smooth zooming for video? FWIW, I am cheap and would prefer not to spend anything more than necessary. Thanks in advance.
