Pentax K100D vs Pentax E70

Here, we will be looking at the Pentax K100D and Pentax E70, one being a Entry-Level DSLR and the latter is a Small Sensor Compact and both are designed by Pentax. There exists a significant gap between the resolutions of the K100D (6MP) and E70 (10MP) and the K100D (APS-C) and E70 (1/2.3") provide different sensor sizing.

The K100D was manufactured 3 years prior to the E70 and that is quite a sizable gap as far as technology is concerned. Both the cameras feature different body design with the Pentax K100D being a Compact SLR camera and the Pentax E70 being a Compact camera.

Before delving straight to a comprehensive comparison, here is a short synopsis of how the K100D scores vs the E70 in terms of portability, imaging, features and an overall rating.

Following is a preview of the gallery photos for Pentax K100D and Pentax Optio E70. The entire galleries are available at Pentax K100D Gallery and Pentax E70 Gallery.

When you are going to carry your camera, you will have to factor its weight and measurements.

Sometimes, it is very tough to visualize the difference between sensor sizing merely by reviewing a spec sheet. The graphic underneath might provide you a better sense of the sensor sizes in the K100D and E70.

Clearly, each of the cameras come with different megapixel count and different sensor sizing. The K100D featuring a bigger sensor is going to make achieving shallow depth of field simpler and the Pentax E70 will offer more detail due to its extra 4 Megapixels. Higher resolution can also allow you to crop pictures a good deal more aggressively. The older K100D is going to be disadvantaged in sensor technology.
