Comparing the Olympus OM-D E-M1, E-M5, and E-M10

Olympus has recently announced a new addition to their OM-D line of Micro Four Thirds cameras, the Olympus OM-D E-M10.  At first it was thought that the OM-D E-M10 would be replacing the E-M5.  However, Olympus intends to keep all three models in their OM-D line of Micro Four Thirds cameras.

In this blog post, I will compare the three Olympus OM-D models and tell you why you might select one over another.  There is also a table near the bottom of the blog post that compares the key features of the OM-D line of cameras.

Olympus OM-D E-M5

The Olympus OM-D E-M1 sits at the top of the OM-D line of cameras.  It is the biggest of the cameras, has the most features, and the highest specifications.  The OM-D E-M1 also has many configurable dials and buttons giving the camera a more professional feel.  The Olympus OM-D E-M1 has the best weather proofing of the 3 OM-D cameras with splash, dust, and freeze resistance.

When you compare the E-M5 to the E-M10, it starts to get more confusing.  The Olympus OM-D E-M5 is an older camera so it has the older version of the TruePIC image processor.  However, it does have splash and dust weather proofing while the new E-M10 does not have any weather proofing.   So if you need weather proofing, that limits your choices to the E-M1 and E-M5.  The E-M5 also has 5-axis image stabilization like the E-M1 while the OM-D E-M10 only has 3-axis image stabilization.

The new E-M10 has some of the new features that are present in the flagship E-M1 camera such as built-in WiFi and Timelapse Recording.  It also has some of the higher specifications that are found in the E-M1 but not in the E-M5.  For example the E-M1 and E-M10 have 81 focus points while the E-M5 only has 35.  The OM-D E-M10 also has a higher resolution LCD screen than the E-M5 with 1,037,000 screen pixels.  The Olympus OM-D E-M10 is also a bit smaller and lighter than the EM-5.

If you don't need weather proofing on your camera and want some of the newer features found in the E-M1, you might want to take a look at the Olympus OM-D E-M10.
