Olympus E-M1 vs Panasonic S1R

Its time to look more closely at the Olympus E-M1 versus Panasonic S1R, both Pro Mirrorless cameras by companies Olympus and Panasonic. There exists a substantial gap among the resolutions of the E-M1 (16MP) and S1R (47MP) and the E-M1 (Four Thirds) and S1R (Full frame) posses different sensor sizes.

The E-M1 was manufactured 6 years earlier than the S1R which is a fairly big difference as far as camera technology is concerned. Both of these cameras feature the same body design (SLR-style mirrorless).

Before getting into a in-depth comparison, here is a brief overview of how the E-M1 scores vs the S1R with regards to portability, imaging, features and an overall mark.

Here is a preview of the gallery photos for Olympus OM-D E-M1 & Panasonic Lumix DC-S1R. The entire galleries are available at Olympus E-M1 Gallery & Panasonic S1R Gallery.

For anyone who is going to travel with your camera regularly, you will want to think about its weight and proportions. The Olympus E-M1 features outside dimensions of 130mm x 94mm x 63mm (5.1" x 3.7" x 2.5") along with a weight of 497 grams (1.10 lbs) while the Panasonic S1R has measurements of 149mm x 110mm x 97mm (5.9" x 4.3" x 3.8") and a weight of 1020 grams (2.25 lbs).

Remember, the weight of an ILC will differ based on the lens you select during that time. Underneath is a front view sizing comparison of the E-M1 and the S1R.

Looking at dimensions and weight, the portability grade of the E-M1 and S1R is 71 and 54 respectively.

More often than not, it can be tough to visualize the contrast in sensor dimensions just by going through a spec sheet. The image here will give you a clearer sense of the sensor sizes in the E-M1 and S1R.

Clearly, both of these cameras feature different resolutions and different sensor dimensions. The E-M1 featuring a smaller sensor is going to make achieving shallower DOF harder and the Panasonic S1R will show more detail due to its extra 31 Megapixels. Higher resolution will help you crop shots way more aggressively. The more aged E-M1 will be disadvantaged with regard to sensor innovation.
