I pondered this myself along with a few other lens considerations before going with the PL. Most people have a problem with the variable aperture, even though it's faster than the 12-100 below 50mm. For my use as an all weather outdoor lens, the speed isn't a huge consideration. The extra reach over the f/2.8 zooms is nice for walk around purposes, and of course having 12mm is nice vs the other "super zooms". If I had an EM1 instead of a G9 I likely would have tried to get a 12-100, for the same reason I went with the PL 12-60 on a Panny body, dual IS. The price is another factor, my used PL 12-60 was $500, I doubt 12-100s are available near that? Like I mentioned above, I just got this lens, but I can post a few of my mediocre picks from a few days ago.i've been interested in the pl12-60/2.8-4 for awhile.
i am surprised by how few images are posted on this thread.
the other lenses i'm looking at, the o12-40/2.8 pro and the o12-100/4 pro, seem to have so many more images (and thus supporters?).
i will continue to hunt for images taken with this lens and see of i can imagine my use of this lens with either my g7 or gx85 (and maybe a g9 in the future?).
thanks to those who have taken the time to share their efforts.
