Olympus TG-1 iHS vs Pentax K20D

The following is a in-depth comparison of the Olympus TG-1 iHS versus Pentax K20D, one is a Waterproof and the latter is a Advanced DSLR by manufacturers Olympus and Pentax. The sensor resolution of the TG-1 iHS (12MP) and the K20D (15MP) is pretty comparable but the TG-1 iHS (1/2.3") and K20D (APS-C) posses totally different sensor sizing.

Photography Glossary

The TG-1 iHS was revealed 3 years after the K20D which is a fairly large gap as far as camera technology is concerned. Both of these cameras have different body design with the Olympus TG-1 iHS being a Compact camera and the Pentax K20D being a Mid-size SLR camera.

Before going right into a detailed comparison, here is a brief overview of how the TG-1 iHS scores versus the K20D with respect to portability, imaging, features and an overall mark.

Below is a preview of the gallery images for Olympus Tough TG-1 iHS and Pentax K20D. The full galleries are provided at Olympus TG-1 iHS Gallery and Pentax K20D Gallery.

For anybody who is looking to travel with your camera regularly, you have to take into account its weight and dimensions. The Olympus TG-1 iHS enjoys outer dimensions of 112mm x 67mm x 30mm (4.4" x 2.6" x 1.2") and a weight of 230 grams (0.51 lbs) whilst the Pentax K20D has dimensions of 142mm x 101mm x 70mm (5.6" x 4.0" x 2.8") with a weight of 800 grams (1.76 lbs).

Remember that, the weight of an Interchangeable Lens Camera will vary dependant on the lens you use during that time. Underneath is a front view dimensions comparison of the TG-1 iHS against the K20D.

Using dimensions and weight, the portability rating of the TG-1 iHS and K20D is 91 and 59 respectively.

Quite often, it's difficult to envision the gap in sensor dimensions simply by checking out specifications. The pic here might offer you a clearer sense of the sensor dimensions in the TG-1 iHS and K20D.

To sum up, both the cameras provide different megapixels and different sensor dimensions. The TG-1 iHS having a smaller sensor will make achieving shallow DOF tougher and the Pentax K20D will produce greater detail because of its extra 3MP. Higher resolution will also enable you to crop photographs more aggressively. The younger TG-1 iHS is going to have an advantage when it comes to sensor innovation.
