Excerpt: This is a must have prime lens for the micro 4/3 system and the second I purchased behind the 20mm f1.7. Great for portraits and short telephoto. I switched to the micro 4/3 system primarily because of size and weight and this lens is a great example of quality in a small package.
Excerpt: Very glad I purchased this lens to use with my Oly e-PM2. 45mm is great for portraits, outdoor shooting, and it's fast. Getting better shots of the kids and sports now. All the reviews describing beautiful bokeh and great shots wide open are right on. I typically keep this lens on my camera all the time, but it's tough for close-ups, but that's not why I purchased it.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Nice Bokeh
Summary: A must have. This is a perfect portrait length lens with gorgeous blur. Simply put, this line is tack sharp edge to edge at 1.8. It produces beautiful images and is well worth the money. I'm a wedding photographer and I proudly use the M43 system (I switched over from Sony a77/99). This lens is my go-to portrait lens.
Summary: I got this to complement the Zuiko 12-40mm f/2.8 Pro on the E-M1 body. I wasn't satisfied with the amount of DOF control I had with the 12-40, since its DOF was roughly equivalent to f/5.6 for 35mm, and that isn't quite shallow enough to isolate the subject from some backgrounds at certain distances.
