Olympus E-PM2 vs Sony A7c

In this write-up, we are looking at the Olympus E-PM2 versus Sony A7c, one being a Entry-Level Mirrorless and the other is a Advanced Mirrorless by competitors Olympus and Sony. There is a significant difference between the image resolutions of the E-PM2 (16MP) and A7c (24MP) and the E-PM2 (Four Thirds) and A7c (Full frame) come with different sensor sizes.

Photography Glossary

The E-PM2 was brought out 8 years prior to the A7c and that is quite a sizable gap as far as tech is concerned. Both cameras offer the identical body type (Rangefinder-style mirrorless).

Before getting straight into a complete comparison, below is a short synopsis of how the E-PM2 scores versus the A7c in terms of portability, imaging, features and an overall grade.

This is a sample of the gallery pics for Olympus PEN E-PM2 and Sony Alpha A7c. The entire galleries are available at Olympus E-PM2 Gallery and Sony A7c Gallery.

For anybody who is planning to lug around your camera regularly, you need to consider its weight and dimensions.

Taking into consideration size and weight, the portability score of the E-PM2 and A7c is 89 and 78 respectively.

Often, it's hard to imagine the gap between sensor measurements only by looking at a spec sheet. The visual below will provide you a much better sense of the sensor sizes in the E-PM2 and A7c.

As you can see, the 2 cameras enjoy different megapixel count and different sensor measurements. The E-PM2 due to its tinier sensor is going to make achieving shallow DOF more difficult and the Sony A7c will resolve more detail having its extra 8 Megapixels. Greater resolution can also allow you to crop pics far more aggressively. The older E-PM2 is going to be disadvantaged with regard to sensor innovation.
