Olympus E-M1 vs Panasonic S1H

Following is a complete review of the Olympus E-M1 versus Panasonic S1H, both Pro Mirrorless digital cameras by manufacturers Olympus and Panasonic. There is a crucial difference between the image resolutions of the E-M1 (16MP) and S1H (24MP) and the E-M1 (Four Thirds) and S1H (Full frame) feature different sensor size.

The E-M1 was released 6 years before the S1H which is quite a serious gap as far as tech is concerned. Each of these cameras offer the identical body type (SLR-style mirrorless).

Before delving straight into a full comparison, below is a short synopsis of how the E-M1 matches up vs the S1H with regards to portability, imaging, features and an overall score.

Here is a sample of the gallery pictures for Olympus OM-D E-M1 and Panasonic Lumix DC-S1H. The complete galleries are viewable at Olympus E-M1 Gallery and Panasonic S1H Gallery.

If you are looking to carry around your camera, you'll need to factor in its weight and measurements. The Olympus E-M1 features external measurements of 130mm x 94mm x 63mm (5.1" x 3.7" x 2.5") and a weight of 497 grams (1.10 lbs) whilst the Panasonic S1H has proportions of 151mm x 114mm x 110mm (5.9" x 4.5" x 4.3") along with a weight of 1052 grams (2.32 lbs).

Bear in mind, the weight of an Interchangeable Lens Camera will change depending on the lens you select at that time. Underneath is the front view measurements comparison of the E-M1 against the S1H.

Factoring in size and weight, the portability grade of the E-M1 and S1H is 71 and 52 respectively.

In many cases, it is very difficult to visualize the gap between sensor sizes only by looking at a spec sheet. The pic below may offer you a better sense of the sensor sizing in the E-M1 and S1H.

As you can see, both of these cameras enjoy different megapixels and different sensor sizes. The E-M1 because of its tinier sensor is going to make shooting shallower DOF trickier and the Panasonic S1H will give you more detail as a result of its extra 8 Megapixels. Greater resolution will allow you to crop pics far more aggressively. The more aged E-M1 is going to be behind with regard to sensor innovation.
