Question: Will this work with an Olympus OM-D E-M5?
Document: I've been incredibly pleased with this lens. Using it on my Olympus OM-D EM-5. It's been much more versatile than I had envisioned, and I find myself leaving this on the camera most of the time. The AF is fast, and the image quality has been superb. For the time being, I don't feel the need for a wider lens, because the 12mm is usually enough and I'm not aware of  better image quality in the wider lenses currently available for the 4/3 platform.
fast, silent, and sharp with fantastic build quality. a gem of lens that takes amazing pictures. Use it as my main lens on the OM-D.
I use this in a trio with the Panasonic 20mm and the Olympus 45mm. It is far away my favorite lens (admittedly, it should be at this price!). I find it renders with just the right amount of character, and it's a perfect 24mm equivalent. It also looks great with the optional metal lens cap, making the entire camera look like a work of art.
I agree with the Reviewer who mentioned how this Lens is by Far the Best M4/3 Lens , both in Build Qualities , and Performance ! I own Many Cameras , and I find This Lens to be very much a Pleasure to both Own , and to Use !!! It is Truly a " Keeper " !!! R E Keay
Excellent Lens with Pen E-P3. Sharp from edge to edge; distortion easily correctable in PhotoShop. High quality finish; looks like a pro lens and performs that way. 2.0 is usable without flash in relatively dark interiors [1250 iso]. A shame that a case and lens hood are not included.
I've taken about 300 photos with this lens and have gotten some really great shotsthat people have really commented on. I'm kind of new to this level of photographyequipment so the only down side to this lens seems to me to be the price. Theconstruction is first rate and looks good on the E-P3 black body. The ability togo to manual focus by pulling back the ring is a great feature.
It even includes the aperture marks on the lens ring - old school. The focusing scale means that you can set this lens for hyperfocal distance focusing and forget it. If you're a landscape shooter or street photographer this is a blessing of the highest order. Shoot at between F/8 and F/11 and everything from about two feet away to infinity will be in focus.As with the other lenses designed to work with the EP3, the autofocus is razor sharp, fast and utterly silent.
I prefer the Olympus 12mm - just looks WAY sharper to me and the continuous auto focus feature is a huge plus.
However, if you need the 9 deg extra FOV or you merely want to use a world class lens then you will be very happy with 12mm f/2. Bravo Olympus.
