Olympus 1s vs Panasonic G100

Let's take a closer look at the Olympus 1s and Panasonic G100, one being a Small Sensor Superzoom and the other is a Entry-Level Mirrorless by companies Olympus and Panasonic. There is a huge difference between the image resolutions of the 1s (12MP) and G100 (20MP) and the 1s (1/1.7") and G100 (Four Thirds) provide different sensor size.

The 1s was released 6 years before the G100 and that is quite a significant gap as far as tech is concerned. Both of the cameras have different body design with the Olympus 1s being a SLR-like (bridge) camera and the Panasonic G100 being a SLR-style mirrorless camera.

Before diving into a thorough comparison, here is a short overview of how the 1s grades against the G100 when considering portability, imaging, features and an overall rating.

This is a sample of the gallery pics for Olympus Stylus 1s and Panasonic Lumix DC-G100. The complete galleries are viewable at Olympus 1s Gallery and Panasonic G100 Gallery.

If you're looking to carry your camera regularly, you're going to have to factor in its weight and volume. The Olympus 1s provides outer measurements of 116mm x 87mm x 57mm (4.6" x 3.4" x 2.2") along with a weight of 402 grams (0.89 lbs) while the Panasonic G100 has sizing of 116mm x 83mm x 54mm (4.6" x 3.3" x 2.1") and a weight of 352 grams (0.78 lbs).

Remember that, the weight of an Interchangeable Lens Camera will differ based on the lens you use at that moment. The following is a front view dimensions comparison of the 1s versus the G100.

Taking into account size and weight, the portability rating of the 1s and G100 is 79 and 81 respectively.

Often, it's hard to visualize the difference between sensor sizing simply by checking specs. The graphic below might provide you a clearer sense of the sensor sizing in the 1s and G100.

As you can plainly see, each of these cameras provide different megapixel count and different sensor sizing. The 1s due to its tinier sensor is going to make getting shallow DOF more difficult and the Panasonic G100 will give more detail as a result of its extra 8 Megapixels. Greater resolution will let you crop photos more aggressively. The older 1s is going to be behind with regard to sensor innovation.
