Olympus E-PM1 vs Olympus TG-860

Here, we will be evaluating the Olympus E-PM1 vs Olympus TG-860, one being a Entry-Level Mirrorless and the latter is a Waterproof and both of them are offered by Olympus. There exists a big gap between the image resolutions of the E-PM1 (12MP) and TG-860 (16MP) and the E-PM1 (Four Thirds) and TG-860 (1/2.3") provide totally different sensor measurements.

The E-PM1 was revealed 4 years before the TG-860 and that is quite a big gap as far as technology is concerned. Each of these cameras feature different body design with the Olympus E-PM1 being a Rangefinder-style mirrorless camera and the Olympus TG-860 being a Ultracompact camera.

Before we go into a detailed comparison, here is a brief introduction of how the E-PM1 grades vs the TG-860 in terms of portability, imaging, features and an overall grade.

Following is a preview of the gallery images for Olympus PEN E-PM1 and Olympus Stylus Tough TG-860. The full galleries are viewable at Olympus E-PM1 Gallery and Olympus TG-860 Gallery.

When you are looking to lug around your camera frequently, you need to factor in its weight and proportions. The Olympus E-PM1 comes with exterior dimensions of 110mm x 64mm x 34mm (4.3" x 2.5" x 1.3") along with a weight of 265 grams (0.58 lbs) whilst the Olympus TG-860 has measurements of 110mm x 64mm x 28mm (4.3" x 2.5" x 1.1") having a weight of 224 grams (0.49 lbs).

Don't forget, the weight of an Interchangeable Lens Camera will differ depending on the lens you use during that time. Below is a front view proportions comparison of the E-PM1 compared to the TG-860.

Considering dimensions and weight, the portability rating of the E-PM1 and TG-860 is 89 and 91 respectively.

Normally, its hard to visualise the contrast between sensor measurements just by checking specs. The graphic here may offer you a much better sense of the sensor dimensions in the E-PM1 and TG-860.

All in all, both cameras come with different megapixel count and different sensor measurements. The E-PM1 with its bigger sensor will make achieving bokeh less difficult and the Olympus TG-860 will resolve greater detail because of its extra 4 Megapixels. Higher resolution will help you crop shots a good deal more aggressively. The older E-PM1 is going to be disadvantaged when it comes to sensor tech.
