Olympus E-5 vs Pentax K20D

Below is a extensive review of the Olympus E-5 vs Pentax K20D, both Advanced DSLR digital cameras by companies Olympus and Pentax. The image resolution of the E-5 (12MP) and the K20D (15MP) is very well matched but the E-5 (Four Thirds) and K20D (APS-C) use different sensor measurements.

Photography Glossary

The E-5 was released 2 years later than the K20D and that is quite a sizable difference as far as tech is concerned. Both the cameras offer the identical body type (Mid-size SLR).

Before going in to a complete comparison, below is a brief view of how the E-5 scores vs the K20D in the way of portability, imaging, features and an overall grade.

Here is a sample of the gallery pics for Olympus E-5 & Pentax K20D. The complete galleries are provided at Olympus E-5 Gallery & Pentax K20D Gallery.

If you are planning to lug around your camera frequently, you'll need to think about its weight and proportions. The Olympus E-5 provides physical measurements of 143mm x 117mm x 75mm (5.6" x 4.6" x 3.0") having a weight of 800 grams (1.76 lbs) and the Pentax K20D has measurements of 142mm x 101mm x 70mm (5.6" x 4.0" x 2.8") having a weight of 800 grams (1.76 lbs).

Always remember, the weight of an ILC will vary based on the lens you have attached at that moment. Following is the front view proportions comparison of the E-5 compared to the K20D.

Factoring in size and weight, the portability rating of the E-5 and K20D is 58 and 59 respectively.

Generally, its tough to picture the difference between sensor measurements purely by checking technical specs. The photograph here should provide you a far better sense of the sensor sizing in the E-5 and K20D.

As you can tell, both of these cameras enjoy different megapixel count and different sensor measurements. The E-5 featuring a tinier sensor is going to make getting shallower DOF more challenging and the Pentax K20D will resolve more detail as a result of its extra 3 Megapixels. Greater resolution will also make it easier to crop pics far more aggressively. The more modern E-5 should have an edge when it comes to sensor tech.
