Olympus TG-5 vs Pentax K-3 II

Below is a complete overview of the Olympus TG-5 and Pentax K-3 II, former being a Waterproof while the latter is a Advanced DSLR by competitors Olympus and Pentax. There is a large difference among the image resolutions of the TG-5 (12MP) and K-3 II (24MP) and the TG-5 (1/2.3") and K-3 II (APS-C) enjoy different sensor sizing.

The TG-5 was revealed 2 years later than the K-3 II and that is a fairly serious difference as far as camera tech is concerned. Both of the cameras come with different body type with the Olympus TG-5 being a Compact camera and the Pentax K-3 II being a Mid-size SLR camera.

Before getting through a complete comparison, below is a short overview of how the TG-5 matches up against the K-3 II in the way of portability, imaging, features and an overall grade.

Here is a preview of the gallery images for Olympus Tough TG-5 & Pentax K-3 II. The full galleries are available at Olympus TG-5 Gallery & Pentax K-3 II Gallery.

If you're looking to lug around your camera often, you're going to have to consider its weight and size.

Remember that, the weight of an ILC will change depending on the lens you have at that moment. The following is the front view physical size comparison of the TG-5 against the K-3 II.

Taking into consideration size and weight, the portability rating of the TG-5 and K-3 II is 90 and 59 respectively.

Usually, it can be difficult to visualize the contrast in sensor measurements just by researching technical specs. The visual below will give you a clearer sense of the sensor sizing in the TG-5 and K-3 II.

As you can tell, the two cameras have got different megapixel count and different sensor measurements. The TG-5 having a smaller sensor is going to make shooting shallow depth of field harder and the Pentax K-3 II will render extra detail because of its extra 12MP. Higher resolution will also help you crop pictures much more aggressively. The more modern TG-5 should have an advantage with regard to sensor technology.
