Olympus E-P1 vs Olympus TG-820 iHS

Let's look more in depth at the Olympus E-P1 versus Olympus TG-820 iHS, one being a Entry-Level Mirrorless and the other is a Waterproof and they are both produced by Olympus. The image resolution of the E-P1 (12MP) and the TG-820 iHS (12MP) is fairly close but the E-P1 (Four Thirds) and TG-820 iHS (1/2.3") have totally different sensor measurements.

The E-P1 was introduced 3 years before the TG-820 iHS and that is a fairly sizable gap as far as camera technology is concerned. Both of the cameras have different body design with the Olympus E-P1 being a Rangefinder-style mirrorless camera and the Olympus TG-820 iHS being a Compact camera.

Before diving into a in depth comparison, here is a brief overview of how the E-P1 matches up against the TG-820 iHS when it comes to portability, imaging, features and an overall rating.

Here is a sample of the gallery pictures for Olympus PEN E-P1 and Olympus TG-820 iHS. The whole galleries are available at Olympus E-P1 Gallery and Olympus TG-820 iHS Gallery.

For anyone who is planning to carry your camera often, you are going to need to factor its weight and proportions. The Olympus E-P1 has got exterior dimensions of 121mm x 70mm x 36mm (4.8" x 2.8" x 1.4") and a weight of 355 grams (0.78 lbs) while the Olympus TG-820 iHS has measurements of 101mm x 65mm x 26mm (4.0" x 2.6" x 1.0") and a weight of 206 grams (0.45 lbs).

Keep in mind, the weight of an Interchangeable Lens Camera will vary depending on the lens you are using at the time. Below is a front view dimensions comparison of the E-P1 versus the TG-820 iHS.

Looking at dimensions and weight, the portability grade of the E-P1 and TG-820 iHS is 86 and 92 respectively.

More often than not, it is very difficult to visualise the difference in sensor sizing only by researching specifications. The visual underneath should provide you a greater sense of the sensor dimensions in the E-P1 and TG-820 iHS.

To sum up, each of the cameras have the same megapixel count but not the same sensor sizing. The E-P1 contains the larger sensor which is going to make achieving bokeh easier. The older E-P1 will be behind in sensor innovation.
