I know so many of you are short of time during the holiday season so I'll keep this short and sweet. I'm mostly a portrait photographer and don't use wide angle lenses all that often. When I do it's usually because we're working with a commercial client on something like an annual report project where, in addition to portraits and photos of people working, we need shots of beautiful business interiors, majestic exterior shots and lenses that are wide enough to make a tiny lab look.....acceptable. I learned a long time ago that wide angles work best when there is something in the foreground, more stuff in the mid-ground and even more stuff in the background. We rarely go searching for "bokeh" when going wide.
I did my research and decided that a micro four thirds system, built around the Panasonic GH5, would best suit my varied needs (video, portraits, general business photography) and I invested in it completely this year. The 40-150mm f2.8 was a "no-brainer" purchase given its incredible performance and nearly perfect focal length range for me. 40mm-60mm is perfect for portraits while the 60-150mm is perfect for documenting live theater at Zach Theatre here in Austin, Texas.
The 12-100mm was a leap of faith. I'd read so many good and great things about it that I decided to try it out as my "all purpose" working lens. It's a constant aperture f4.0 which is great for most stuff. I'm happy I took the plunge because it very sharp at all focal lengths and all the other characteristics which people worry about are equally well handled.
For a week or so I thought that the short end of the 12-100mm would handle most of my wide angle needs but a job came along that required a bit wider field of view. I started researching the available wide angles in earnest. I wanted a zoom, and, after my experiences with the Olympus Pro series lenses, I knew I wanted to look at the top of the range of what is available. The advantages of premium glass are, if anything, even more obvious with the smaller sensor cameras....
I had previously owned the Pansonic 7-14mm f4.0 and had some niggling criticisms of it. The corners weren't perfect and the bulbous front made any sort of convenient filtering impossible. I've read amazing things about the Olympus 7-14mm f2.8 Pro so I tried that lens on loan. It's fabulous! Maybe even a little bit better than the lens I ended up with but for a photographer who
