The 25 mm F 1.2 pro is my fourth Olympus pro lens, after the 12-40 F 2.8, 40-150 F 2.8, and 7-14 F 2.8 zooms, so first a few comments on the pro lens line in general. Amazing optical quality, features, and feel are why I keep coming back for more. Although hardly a professional photographer, these lens make me look and feel like one. That said, recognize that these lens have heft. While Olympus is recognized for quality 4/3 cameras that are smaller than the Nikon/Canon competition, attach one of the Olympus pro lens and you will be adding significant weight to your camera—and camera bag. For those wishing to travel light, the pro lens may not be for you. The 25 mm F 1.2 is a great walk-about lens in that what you see with the naked eye is what you see through the view finder. It also offers great low-light capability and bokeh pop. At F 1.2 you can literally take decent pictures in the dark. Just beware of the VERY shallow depth of field at F 1.2. Particularly for close subjects, you need to be very careful that you are focusing on exactly what you want since much of rest of the picture will be a blur. Because in auto or program mode, the camera will often default to F 1.2 in lower light situations, I’ve found it’s better for me to use aperture preferred so I can better control the depth of field. In sum, I like the lens, but unless you need a rugged pro lens with great low light and bokeh capabilities, this might not be the lens for you.
