12 mm
Ahhhh. Reviews on the web. Reviews on the lens review sites. Hmmmm. No. As most of you know I'm not much inclined to use wider angle lenses except out of necessity. Like those times that the paying client wants just a bit more in the frame. Or occasions when I want to make the client's 400 square foot "factory" look---interesting.
Well I recently accepted an assignment to go to Fredericksburg, Texas and photograph a house for a national shelter magazine. Of course I decided to shoot the whole assignment on micro four thirds because, well.....I'm not sure why. It just seems like the fun thing to do. Then I thought back over thirty years of assignments for shelter magazines and remembered that many of the establishing shots we did depended on wider angle lenses. 90mm on my old Linhof 4x5. The 38mm Biogon on my Hasselblad Superwide, etc. and I realized that the widest optic I had for the new Panasonic GH3's (and that darling G6) was the 14-42 kit lens. Well, that just wouldn't cut it. So I started to go through my options. I could buy a Panasonic 7-14mm but that's a lot of cash for something I rarely want to use. I could save a few bucks by getting the Olympus 12mm f2 but, again, lots of cash. I started looking around at the other options. After all, this m4:3rd system is supposed to be powerful when it comes to the sheer amount of lenses available, right?
Well, I did find one option that was much cheaper and would give me the 12mm I was looking for but there were a few issues.....it must be the most maligned zoom lens on webdom today. Every site I went to for reviews talked about the vicious vignetting, the mediocre sharpness and the woefully dark aperture at the long end. I came away thinking the lens would make edge lines curvier than a Slinky at the wide end, with blackened corners from vignetting while the long end would be like there was a number 10 soft focus filter permanently attached. And all through the reviews I was given to believe that the 1/3 smaller f-stop would making viewing images at the long end of the zoom like looking through a beefy neutral density filter. I vacillated for a day and looked around for more bargains. Finally, I found the lens in question, used, for a little over $200 and thought, "I've made more stupid gambles so...why not?"
It thought this was pretty good for a handheld twilight shot at 12mm but I thought the
image stabilization was a big help....until I realized that neither the lens nor the
camera (G6) has image stabilization....
Not finding too much problem with flare...
see the full 12mm frame below. This is a crop...
Start your pixel peeping engines!!!
And the Panasonic G6 even corrected the geometry of the lens...wide open at 12mm.
Confused that I might have gotten too sharp a version.....
Nearly wide open @ 12mm. Still looking for the vignetting...
50mm wide open at f6.3
Some topical holiday imagery from a scouting trip today.
Well, the lens in question is an Olympus 12-50mm, f3.5 to f6.3. I bought it assuming the reviews would be right and I'd be left with a lens that was, um, at least weatherproof. But now that I've gotten to know it a little better I'll be happy to shoot with it. Seems sharp at both ends and in the middle. The rival camera companies (Panasonic vs. Olympus) seem to have worked out some sort of truce that allows them to correct each other's lenses for geometry, vignetting and chromatic aberrations. And what I'm left with is a lens that's more than adequate for my intended use at a very agreeable price. Plus I have a 20 stop image stabilization device I'm just aching to try with this lens. It's called a tripod....
The lens is goofy. It has a motorized zoom. But you can turn it off and zoom it with your finders. It has a button on the side that doesn't do anything on Panasonic cameras and it's long and skinny and plastic. If you can get over those things it is actually a nice lens for general photography in good light. My quest is (for now) over. Almost forgot: it also kinda does macro.
That's my review of the Olympus 12-50mm lens. It's been Tuck Tested and found to be more than acceptable.
