Pentax I-10 vs Pentax RZ18

The following is a in-depth comparison of the Pentax I-10 versus Pentax RZ18, one is a Small Sensor Compact and the latter is a Small Sensor Superzoom and both of them are built by Pentax. There exists a sizeable gap between the image resolutions of the I-10 (12MP) and RZ18 (16MP) but they use the exact same sensor size (1/2.3").

The I-10 was introduced 19 months prior to the RZ18 which makes the cameras a generation away from one another. Both the cameras come with the identical body type (Compact).

Before diving in to a step-by-step comparison, below is a quick summation of how the I-10 scores versus the RZ18 when considering portability, imaging, features and an overall mark.

For those who are looking to travel with your camera regularly, you will need to consider its weight and size. The Pentax I-10 has got external dimensions of 101mm x 65mm x 28mm (4.0" x 2.6" x 1.1") and a weight of 153 grams (0.34 lbs) and the Pentax RZ18 has specifications of 97mm x 61mm x 33mm (3.8" x 2.4" x 1.3") along with a weight of 178 grams (0.39 lbs).

Keep in mind, the weight of an Interchangeable Lens Camera will vary depending on the lens you select at that moment. Following is the front view measurements comparison of the I-10 versus the RZ18.

Taking into consideration dimensions and weight, the portability grade of the I-10 and RZ18 is 93 and 92 respectively.

Quite often, it is very difficult to visualise the difference between sensor dimensions merely by reading specifications. The pic underneath should give you a far better sense of the sensor dimensions in the I-10 and RZ18.

To sum up, both of these cameras have got the exact same sensor measurements albeit not the same resolution. You should count on the Pentax RZ18 to offer you greater detail using its extra 4MP. Higher resolution will allow you to crop pictures much more aggressively. The more aged I-10 is going to be disadvantaged with regard to sensor innovation.
