Olympus 1s vs Pentax K-7

On this page, we will be reviewing the Olympus 1s versus Pentax K-7, one being a Small Sensor Superzoom and the latter is a Advanced DSLR by manufacturers Olympus and Pentax. The resolution of the 1s (12MP) and the K-7 (15MP) is relatively well matched but the 1s (1/1.7") and K-7 (APS-C) offer totally different sensor measurements.

The 1s was released 5 years later than the K-7 and that is quite a significant gap as far as tech is concerned. The two cameras have different body design with the Olympus 1s being a SLR-like (bridge) camera and the Pentax K-7 being a Mid-size SLR camera.

Before going into a more detailed comparison, here is a simple summation of how the 1s grades versus the K-7 in terms of portability, imaging, features and an overall grade.

Below is a preview of the gallery photos for Olympus Stylus 1s and Pentax K-7. The complete galleries are viewable at Olympus 1s Gallery and Pentax K-7 Gallery.

For those who are aiming to lug around your camera regularly, you should factor its weight and volume. The Olympus 1s enjoys external measurements of 116mm x 87mm x 57mm (4.6" x 3.4" x 2.2") accompanied by a weight of 402 grams (0.89 lbs) and the Pentax K-7 has sizing of 131mm x 97mm x 73mm (5.2" x 3.8" x 2.9") having a weight of 750 grams (1.65 lbs).

Take into consideration, the weight of an Interchangeable Lens Camera will differ dependant on the lens you are using at that time. Below is a front view overall size comparison of the 1s vs the K-7.

Taking into consideration size and weight, the portability score of the 1s and K-7 is 79 and 60 respectively.

Generally, it is tough to see the contrast between sensor measurements only by checking specifications. The visual here will help give you a clearer sense of the sensor measurements in the 1s and K-7.

To sum up, each of these cameras have different resolutions and different sensor measurements. The 1s due to its tinier sensor will make achieving shallower depth of field more challenging and the Pentax K-7 will give you greater detail as a result of its extra 3 Megapixels. Higher resolution can also allow you to crop pictures a bit more aggressively. The fresher 1s will have an edge in sensor innovation.
