Pentax H90 vs Pentax RZ18

Here, we are reviewing the Pentax H90 versus Pentax RZ18, one is a Small Sensor Compact and the other is a Small Sensor Superzoom and both of them are built by Pentax. There exists a significant gap between the sensor resolutions of the H90 (12MP) and RZ18 (16MP) but both cameras provide the identical sensor size (1/2.3").

The H90 was unveiled 19 months before the RZ18 making them a generation away from one another. Both of the cameras feature the same body design (Compact).

Before going into a in depth comparison, here is a simple summation of how the H90 scores vs the RZ18 with respect to portability, imaging, features and an overall mark.

This is a sample of the gallery pictures for Pentax Optio H90 and Pentax Optio RZ18. The full galleries are available at Pentax H90 Gallery and Pentax RZ18 Gallery.

For anyone who is aiming to travel with your camera regularly, you'll need to factor its weight and measurements. The Pentax H90 provides outside measurements of 101mm x 65mm x 28mm (4.0" x 2.6" x 1.1") with a weight of 153 grams (0.34 lbs) while the Pentax RZ18 has proportions of 97mm x 61mm x 33mm (3.8" x 2.4" x 1.3") with a weight of 178 grams (0.39 lbs).

Don't forget, the weight of an Interchangeable Lens Camera will differ dependant on the lens you have at that time. Below is a front view scale comparison of the H90 versus the RZ18.

Looking at dimensions and weight, the portability score of the H90 and RZ18 is 93 and 92 respectively.

Typically, it is very difficult to envision the difference between sensor dimensions merely by going over specifications. The image below will help provide you a stronger sense of the sensor sizing in the H90 and RZ18.

To sum up, the 2 cameras feature the identical sensor size but not the same MP. You should anticipate the Pentax RZ18 to offer you more detail having an extra 4MP. Greater resolution will make it easier to crop images way more aggressively. The more aged H90 is going to be disadvantaged in sensor tech.
