I would kick it up another notch were it not for the raspy lens mount. I purchased the lens to replace the original 4/3 30mm x 3.5 that I use with the MMF adapter. Now after comparing the new lens to the old lens, I am returning it. While the glass is the usual Olympus superior quality, the physical build is not. Mounting the lens to either my E-M5 or E-M5 mk II is rough and scratchy making it feel like there is sand between the lens and the camera body. After processing and comparing several runs of shots on each body using both lenses, I really can't justify keeping it. I find the shallow depth of field is visually the same with both lenses even though the minimum focus is slightly closer on the newly released micro 4/3 lens.
