Olympus E-M1 II vs Sigma fp

Below is a complete comparison of the Olympus E-M1 II and Sigma fp, one being a Pro Mirrorless and the other is a Advanced Mirrorless by competitors Olympus and Sigma. The image resolution of the E-M1 II (20MP) and the fp (25MP) is very comparable but the E-M1 II (Four Thirds) and fp (Full frame) possess different sensor dimensions.

The E-M1 II was unveiled 3 years earlier than the fp and that is a fairly significant gap as far as camera tech is concerned. The two cameras offer different body type with the Olympus E-M1 II being a SLR-style mirrorless camera and the Sigma fp being a Rangefinder-style mirrorless camera.

Before getting through a step-by-step comparison, below is a quick overview of how the E-M1 II grades vs the fp in terms of portability, imaging, features and an overall grade.

Following is a sample of the gallery pics for Olympus OM-D E-M1 Mark II and Sigma fp. The full galleries are provided at Olympus E-M1 II Gallery and Sigma fp Gallery.

If you're looking to lug around your camera, you will have to consider its weight and measurements. The Olympus E-M1 II has got physical measurements of 134mm x 91mm x 67mm (5.3" x 3.6" x 2.6") along with a weight of 574 grams (1.27 lbs) and the Sigma fp has proportions of 113mm x 70mm x 45mm (4.4" x 2.8" x 1.8") and a weight of 422 grams (0.93 lbs).

Keep in mind, the weight of an Interchangeable Lens Camera will differ depending on the lens you have attached at that time. Below is the front view size comparison of the E-M1 II against the fp.

Taking into consideration size and weight, the portability grade of the E-M1 II and fp is 68 and 84 respectively.

Generally, it is very difficult to visualize the gap in sensor measurements only by checking out technical specs. The visual below might provide you a much better sense of the sensor measurements in the E-M1 II and fp.

As you have seen, both of those cameras enjoy different resolutions and different sensor measurements. The E-M1 II with its smaller sensor is going to make getting shallow DOF trickier and the Sigma fp will produce extra detail having an extra 5MP. Greater resolution will also allow you to crop pics far more aggressively. The older E-M1 II will be behind with regard to sensor tech.
