Pentax RZ18 vs Ricoh WG-5 GPS

Below is a extensive comparison of the Pentax RZ18 and Ricoh WG-5 GPS, one being a Small Sensor Superzoom and the other is a Waterproof by brands Pentax and Ricoh. The image resolution of the RZ18 (16MP) and the WG-5 GPS (16MP) is fairly well matched and they enjoy the exact same sensor sizes (1/2.3").

Meta to Introduce 'AI-Generated' Labels for Media starting next month

The RZ18 was introduced 4 years prior to the WG-5 GPS and that is quite a large gap as far as technology is concerned. Both of these cameras come with the identical body type (Compact).

Before getting straight into a detailed comparison, below is a short introduction of how the RZ18 matches up vs the WG-5 GPS with regard to portability, imaging, features and an overall grade.

This is a sample of the gallery pictures for Pentax Optio RZ18 and Ricoh WG-5 GPS. The whole galleries are viewable at Pentax RZ18 Gallery and Ricoh WG-5 GPS Gallery.

If you're looking to lug around your camera regularly, you will need to consider its weight and dimensions. The Pentax RZ18 provides outer measurements of 97mm x 61mm x 33mm (3.8" x 2.4" x 1.3") with a weight of 178 grams (0.39 lbs) whilst the Ricoh WG-5 GPS has dimensions of 125mm x 65mm x 32mm (4.9" x 2.6" x 1.3") accompanied by a weight of 236 grams (0.52 lbs).

Keep in mind, the weight of an Interchangeable Lens Camera will differ based on the lens you have at that moment. Following is the front view physical size comparison of the RZ18 against the WG-5 GPS.

Taking into consideration dimensions and weight, the portability grade of the RZ18 and WG-5 GPS is 92 and 90 respectively.

Normally, it is hard to picture the difference between sensor measurements simply by reading through a spec sheet. The photograph here might offer you a much better sense of the sensor measurements in the RZ18 and WG-5 GPS.

As you can see, both of those cameras have got the exact same sensor measurements and the same megapixels therefore you should expect similar quality of files but you may want to take the release date of the products into consideration. The older RZ18 is going to be disadvantaged with regard to sensor innovation.
