Olympus TG-320 vs Pentax K-r

Lets look a bit more closely at the Olympus TG-320 and Pentax K-r, one being a Waterproof and the latter is a Entry-Level DSLR by competitors Olympus and Pentax. The sensor resolution of the TG-320 (14MP) and the K-r (12MP) is pretty well matched but the TG-320 (1/2.3") and K-r (APS-C) enjoy different sensor dimensions.

The TG-320 was revealed 11 months later than the K-r so they are both of a similar generation. Each of the cameras come with different body type with the Olympus TG-320 being a Compact camera and the Pentax K-r being a Compact SLR camera.

Before going in to a in-depth comparison, below is a concise view of how the TG-320 scores against the K-r when it comes to portability, imaging, features and an overall grade.

In case you're going to lug around your camera regularly, you will need to think about its weight and size. The Olympus TG-320 has got external dimensions of 96mm x 63mm x 23mm (3.8" x 2.5" x 0.9") having a weight of 155 grams (0.34 lbs) and the Pentax K-r has specifications of 125mm x 97mm x 68mm (4.9" x 3.8" x 2.7") having a weight of 598 grams (1.32 lbs).

Don't forget, the weight of an Interchangeable Lens Camera will vary based on the lens you use at that moment. Underneath is the front view measurement comparison of the TG-320 compared to the K-r.

Using size and weight, the portability grade of the TG-320 and K-r is 94 and 67 respectively.

Generally, it is difficult to imagine the gap between sensor measurements simply by looking at a spec sheet. The photograph underneath may give you a more clear sense of the sensor sizes in the TG-320 and K-r.

Clearly, both cameras have got different megapixel count and different sensor measurements. The TG-320 using its tinier sensor is going to make achieving shallow depth of field harder and the Olympus TG-320 will give you greater detail because of its extra 2MP. Higher resolution will also enable you to crop photographs much more aggressively. The newer TG-320 should have an advantage when it comes to sensor innovation.
