Olympus TG-3 vs Pentax K-1 II

Below is a extended assessment of the Olympus TG-3 and Pentax K-1 II, former being a Waterproof while the latter is a Advanced DSLR by companies Olympus and Pentax. There exists a considerable gap between the sensor resolutions of the TG-3 (16MP) and K-1 II (36MP) and the TG-3 (1/2.3") and K-1 II (Full frame) come with totally different sensor sizes.

The TG-3 was brought out 4 years before the K-1 II and that is quite a large difference as far as technology is concerned. The two cameras come with different body type with the Olympus TG-3 being a Compact camera and the Pentax K-1 II being a Mid-size SLR camera.

Before we go in to a step-by-step comparison, below is a brief introduction of how the TG-3 scores against the K-1 II with respect to portability, imaging, features and an overall grade.

This is a preview of the gallery images for Olympus Tough TG-3 & Pentax K-1 Mark II. The entire galleries are provided at Olympus TG-3 Gallery & Pentax K-1 II Gallery.

For those who are looking to lug around your camera regularly, you will have to factor its weight and size. The Olympus TG-3 has outside measurements of 112mm x 66mm x 31mm (4.4" x 2.6" x 1.2") with a weight of 247 grams (0.54 lbs) and the Pentax K-1 II has specifications of 137mm x 110mm x 86mm (5.4" x 4.3" x 3.4") along with a weight of 1010 grams (2.23 lbs).

Don't forget, the weight of an ILC will vary dependant on the lens you have attached during that time. Following is the front view sizing comparison of the TG-3 and the K-1 II.

Taking into consideration dimensions and weight, the portability score of the TG-3 and K-1 II is 90 and 55 respectively.

Sometimes, it can be difficult to visualise the gap between sensor measurements purely by looking at a spec sheet. The photograph below will give you a clearer sense of the sensor measurements in the TG-3 and K-1 II.

As you can see, the 2 cameras posses different megapixel count and different sensor measurements. The TG-3 featuring a tinier sensor will make achieving shallower DOF harder and the Pentax K-1 II will give greater detail having its extra 20 Megapixels. Higher resolution will also enable you to crop shots somewhat more aggressively. The older TG-3 is going to be behind with regard to sensor technology.
