Olympus E-1 vs Pentax K-7

Let's look a bit more closely at the Olympus E-1 versus Pentax K-7, former is a Pro DSLR while the latter is a Advanced DSLR by rivals Olympus and Pentax. There is a noticeable difference between the sensor resolutions of the E-1 (5MP) and K-7 (15MP) and the E-1 (Four Thirds) and K-7 (APS-C) have different sensor measurements.

The E-1 was released 6 years prior to the K-7 which is quite a sizable difference as far as tech is concerned. Both of the cameras have different body design with the Olympus E-1 being a Large SLR camera and the Pentax K-7 being a Mid-size SLR camera.

Before delving into a more detailed comparison, here is a quick summation of how the E-1 grades against the K-7 when it comes to portability, imaging, features and an overall score.

Often, its hard to imagine the contrast between sensor sizes merely by going over a spec sheet. The picture underneath should give you a stronger sense of the sensor measurements in the E-1 and K-7.

As you can see, both the cameras provide different megapixel count and different sensor sizes. The E-1 because of its tinier sensor is going to make getting shallower depth of field more difficult and the Pentax K-7 will offer greater detail as a result of its extra 10 Megapixels. Higher resolution will help you crop photographs more aggressively. The more aged E-1 is going to be behind with regard to sensor tech.
