Olympus E-500 vs Pentax K-7

Here, we will be contrasting the Olympus E-500 versus Pentax K-7, both Advanced DSLR cameras by manufacturers Olympus and Pentax. There exists a sizeable gap among the sensor resolutions of the E-500 (8MP) and K-7 (15MP) and the E-500 (Four Thirds) and K-7 (APS-C) provide different sensor dimensions.

The E-500 was announced 5 years earlier than the K-7 and that is a fairly large gap as far as camera technology is concerned. Both cameras feature the same body design (Mid-size SLR).

Before we go into a step-by-step comparison, here is a simple view of how the E-500 matches up versus the K-7 in regards to portability, imaging, features and an overall grade.

Following is a preview of the gallery photos for Olympus E-500 and Pentax K-7. The whole galleries are viewable at Olympus E-500 Gallery and Pentax K-7 Gallery.

If you are looking to lug around your camera frequently, you'll have to factor its weight and size. The Olympus E-500 provides physical dimensions of 130mm x 95mm x 66mm (5.1" x 3.7" x 2.6") accompanied by a weight of 479 grams (1.06 lbs) whilst the Pentax K-7 has specifications of 131mm x 97mm x 73mm (5.2" x 3.8" x 2.9") accompanied by a weight of 750 grams (1.65 lbs).

Don't forget, the weight of an Interchangeable Lens Camera will differ dependant on the lens you are utilising at that time. Following is a front view physical size comparison of the E-500 and the K-7.

Factoring in dimensions and weight, the portability rating of the E-500 and K-7 is 70 and 60 respectively.

Sometimes, it is hard to picture the gap in sensor measurements purely by checking out technical specs. The graphic underneath might offer you a stronger sense of the sensor sizes in the E-500 and K-7.

As you have seen, both of those cameras come with different resolutions and different sensor measurements. The E-500 with its smaller sensor is going to make getting bokeh harder and the Pentax K-7 will provide more detail with its extra 7 Megapixels. Higher resolution can also enable you to crop shots a good deal more aggressively. The older E-500 will be disadvantaged in sensor tech.
