Olympus TG-4 vs Pentax K100D

Below is a complete assessment of the Olympus TG-4 versus Pentax K100D, former being a Waterproof while the latter is a Entry-Level DSLR by companies Olympus and Pentax. There exists a sizable gap between the image resolutions of the TG-4 (16MP) and K100D (6MP) and the TG-4 (1/2.3") and K100D (APS-C) come with different sensor sizes.

The TG-4 was brought out 8 years later than the K100D and that is quite a significant difference as far as technology is concerned. Both cameras offer different body type with the Olympus TG-4 being a Compact camera and the Pentax K100D being a Compact SLR camera.

Before going through a in depth comparison, below is a simple introduction of how the TG-4 scores against the K100D with respect to portability, imaging, features and an overall grade.

For those who are going to lug around your camera, you are going to need to factor its weight and volume. The Olympus TG-4 enjoys outer measurements of 112mm x 66mm x 31mm (4.4" x 2.6" x 1.2") and a weight of 247 grams (0.54 lbs) whilst the Pentax K100D has sizing of 129mm x 93mm x 70mm (5.1" x 3.7" x 2.8") with a weight of 660 grams (1.46 lbs).

Do not forget, the weight of an ILC will differ based on the lens you have chosen at that time. Underneath is the front view overall size comparison of the TG-4 and the K100D.

Factoring in dimensions and weight, the portability score of the TG-4 and K100D is 90 and 64 respectively.

Quite often, it is very tough to picture the gap between sensor measurements only by going over a spec sheet. The photograph below will offer you a greater sense of the sensor measurements in the TG-4 and K100D.

Clearly, each of the cameras offer different megapixel count and different sensor measurements. The TG-4 due to its tinier sensor is going to make achieving bokeh trickier and the Olympus TG-4 will offer more detail having its extra 10 Megapixels. Higher resolution will make it easier to crop photographs a little more aggressively. The younger TG-4 should have an edge in sensor technology.
