Olympus E-400 vs Pentax Q10

Let's look more closely at the Olympus E-400 versus Pentax Q10, one being a Entry-Level DSLR and the latter is a Entry-Level Mirrorless by rivals Olympus and Pentax. The resolution of the E-400 (10MP) and the Q10 (12MP) is relatively well matched but the E-400 (Four Thirds) and Q10 (1/2.3") provide different sensor sizing.

The E-400 was announced 7 years before the Q10 and that is quite a large gap as far as tech is concerned. Both of these cameras have different body design with the Olympus E-400 being a Compact SLR camera and the Pentax Q10 being a Rangefinder-style mirrorless camera.

Before going right into a thorough comparison, here is a quick view of how the E-400 grades against the Q10 with regards to portability, imaging, features and an overall grade.

The following is a preview of the gallery photos for Olympus E-400 and Pentax Q10. The whole galleries are viewable at Olympus E-400 Gallery and Pentax Q10 Gallery.

If you are looking to lug around your camera often, you will have to think about its weight and proportions. The Olympus E-400 has outside measurements of 130mm x 91mm x 53mm (5.1" x 3.6" x 2.1") with a weight of 435 grams (0.96 lbs) while the Pentax Q10 has measurements of 102mm x 58mm x 34mm (4.0" x 2.3" x 1.3") having a weight of 200 grams (0.44 lbs).

Take into consideration, the weight of an Interchangeable Lens Camera will change dependant on the lens you are utilising during that time. Below is a front view scale comparison of the E-400 against the Q10.

Using size and weight, the portability score of the E-400 and Q10 is 77 and 92 respectively.

Generally, it is difficult to picture the difference between sensor measurements only by reading through a spec sheet. The visual below might offer you a clearer sense of the sensor measurements in the E-400 and Q10.

Clearly, each of the cameras provide different megapixel count and different sensor measurements. The E-400 with its bigger sensor is going to make achieving shallower depth of field easier and the Pentax Q10 will resolve greater detail with its extra 2 Megapixels. Higher resolution can also enable you to crop pictures more aggressively. The older E-400 is going to be disadvantaged in sensor innovation.
