I recently got a second hand Olympus E-M5. It is not that I don’t like the E-P5 but I wanted to have a better grip and the viewfinder integrated in the body.
I found some E-M1s but they were too pricey and this E-M5 looked good, so I took a chance at it.
The E-M5 and the E-P5 are basically the same regarding technologies included but there are some differences and E-P5 has a slightly better performance on high ISO. On the other hand, the E-M5 has a better grip though it is smaller than I thought and it is basically the same size than the E-P5, only that it is a bit taller because of the integrated viewfinder.
I went out to test it and I liked it very much but even having a better grip compared to the E-P5, I have ordered and additional grip on amazon to enhance even more the ergonomics.
