Since buying the P14, PL25, and O45, I have become an almost exclusive prime shooter, which is a surprise to me because when I had a Canon dslr I shot 2.8 zooms almost exclusively. And for the record I am totally happy with my three primes. But, there are times when I wonder if the versatility of a zoom would be a better compromise than carrying around three primes and switching them out. I actually have two zoom lenses at the moment. I have the O14-42IIr that came with with my E-PM1 and I purchased the O40-150 when it was so cheap a while back. I have been blown away by the results with the 40-150 considering its cost and cheap construction. I have not been blown away by the 14-42. It is ok, but not great. So, I have been thinking about buying a normal zoom at some point in the future. I have read good things about the 14-45, with many considering it the best of the cheap kit zooms. I have even read that its IQ is not much behind the 12-35 if it is behind it at all. I can pick one up used on ebay for less than $200 all day long. Of course, the 12-35 is Panasonic's flag ship normal zoom and is priced accordingly. It is still a good deal compared with a Canon 24-70 2.8, but that is another story. I'm leaning toward picking up a used 14-45, but I'd be interested in hearing from people who have used both and their opinion on whether the 12-35 is really worth 5 TIMES the money. Also, I'd be interested in hearing whether the 14-45 is really much if any better than the O14-42 I already have. One point in the Panasonic's favor is the OIS, as my main camera at present is a G5. I've never really had a camera with IBIS that made much of a difference nor lenses with IS. I know that is amazing to some, as I see posts all the time basically commenting that without some form of IS, a camera/lens is worthless. I am obviously not in that camp, but I wouldn't mind seeing what I am missing. That is the reason I'm not really considering the otherwise excellent O12-40. Thanks.
