Bear in mind, the weight of an ILC will change based on the lens you have chosen at the time. Below is a front view proportions comparison of the E-PM1 versus the I-10.

Taking into consideration size and weight, the portability rating of the E-PM1 and I-10 is 89 and 93 respectively.

Oftentimes, it is tough to picture the gap in sensor measurements just by checking out a spec sheet. The photograph underneath may offer you a much better sense of the sensor dimensions in the E-PM1 and I-10.

Clearly, both the cameras have the same MP but different sensor measurements. The E-PM1 comes with the larger sensor which will make achieving shallower depth of field simpler. The more modern E-PM1 should have an edge with regard to sensor innovation.
