Review on 📷 Olympus M. Zuiko Digital ED 12mm f/2.0 Lens - International Version (No Warranty) | Micro Four Thirds Cameras by Sarah Moore

Updated Review 11/10/2015: I am less satisfied with this lens than originally stated in the previous review. Of course the small size and f/2.0 is a plus compared to my Panasonic 7-14MM, but every time I use an Olympus I regret not having bought a Panasonic lens. The main reason is that the results just aren't that sharp. This may be because the Panasonic performs better with onboard image stabilization, or the Olympus has a much shallower depth of field at f/2.0, but few Olympus shots come out as sharp as I expected. That and that I'm used to the 7-14mm field of view now and expect the 12mm Olympus to make me feel like I'm missing something in the framing. First review: I bought this lens to complement my Panasonic 7-14mm f/4.0 because it's physically smaller and faster at f/2.0. Now I'm not sure if that was reasonable in hindsight. Used an Olympus for a while with good results but it's not as sharp as the Panasonic 7-14mm. And now that I'm used to the 7mm ultra wide, I'm having a hard time confining myself to the 12mm Olympus (no fault of the lens) as I've trained myself to see the world in 7th mm to see. I thought the speed factor would be useful, up to 2 stops faster, but my Panasonic GX7 is so good at rendering at high ISOs that speed doesn't make as much of a difference as I thought. The smaller Olympus 12mm is an advantage, but most 4/3 mirrorless cameras, like my Panasonic GX7, aren't very pocket-friendly anyway, be it a big lens or a small one. And in terms of actual size and feel, the difference between these two already compact lenses isn't something I think about as I walk out the door. Inevitably, I always use a Panasonic lens because it's sharper and wider.
