Olympus E-400 vs Pentax Q7

Following is a in depth assessment of the Olympus E-400 and Pentax Q7, one is a Entry-Level DSLR and the latter is a Entry-Level Mirrorless by competitors Olympus and Pentax. The resolution of the E-400 (10MP) and the Q7 (12MP) is relatively well matched but the E-400 (Four Thirds) and Q7 (1/1.7") feature totally different sensor sizes.

The E-400 was revealed 7 years prior to the Q7 which is quite a serious gap as far as technology is concerned. Both the cameras come with different body type with the Olympus E-400 being a Compact SLR camera and the Pentax Q7 being a Rangefinder-style mirrorless camera.

Before we go in to a comprehensive comparison, below is a short summary of how the E-400 grades vs the Q7 for portability, imaging, features and an overall score.

Following is a preview of the gallery photos for Olympus E-400 and Pentax Q7. The full galleries are available at Olympus E-400 Gallery and Pentax Q7 Gallery.

For those who are aiming to carry around your camera regularly, you will need to think about its weight and measurements.

Typically, it is difficult to envision the gap between sensor sizes just by looking at specifications. The picture below might give you a far better sense of the sensor measurements in the E-400 and Q7.

Plainly, both of those cameras have got different megapixel count and different sensor sizes. The E-400 with its bigger sensor will make shooting shallow DOF simpler and the Pentax Q7 will resolve extra detail because of its extra 2MP. Higher resolution will help you crop pictures much more aggressively. The more aged E-400 is going to be behind when it comes to sensor technology.
