I have been thinking of buying the legendary Panasonic 14-45mm for years now. I actually ordered it (used, for $180) from Amazon a few days ago, but I had serious second thoughts and decided to cancel the order today. I already have the 14-42mm that came with my GH2. I know the image quality is not as good, but after re-visiting some old threads, it seems like it's close enough to not warrant the upgrade. I also gave up on the 12-32mm, since it apparently exhibits shutter shock at 32mm under certain conditions, and my GH2 does not have an electronic shutter option. So I'd rather try to save the money for the 15mm f1.7 - maybe it will come down closer to $500 in October.
Now, one of the main reasons that I wanted the 14-45mm for was smooth zoom action. The 14-42 is very jerky, and it's a problem when shooting video (although motorized zoom would be ideal). I was wondering if there was a way to approach the smoothness of the 45-150mm by lubricating the outside of the zoom cylinder with a little WD40 to help it glide better. Is there any risk at all of the lubricant getting into the optical elements? I realize that it's not a weather sealed lens, but lubricants do adhere to the surface they are applied on, so I'm hoping that it wouldn't start spreading on the inside.
My idea is to spray some WD40 (I also have some gel grease around as an alternate, and that won't run at all under normal temperatures) on a napkin and rub it on the zoom barrel to form a thin film.
Has anyone else tried something similar? Is there a chance of screwing this up and destroying the lens?
