Panasonic 3D1 vs Pentax K-7

Its time to examine more closely at the Panasonic 3D1 and Pentax K-7, former is a Small Sensor Compact while the other is a Advanced DSLR by manufacturers Panasonic and Pentax. The image resolution of the 3D1 (12MP) and the K-7 (15MP) is very similar but the 3D1 (1/2.3") and K-7 (APS-C) feature totally different sensor dimensions.

The 3D1 was introduced 2 years after the K-7 which is quite a serious difference as far as technology is concerned. Both cameras come with different body type with the Panasonic 3D1 being a Compact camera and the Pentax K-7 being a Mid-size SLR camera.

Before going through a in depth comparison, below is a concise highlight of how the 3D1 grades vs the K-7 with regards to portability, imaging, features and an overall score.

This is a sample of the gallery pics for Panasonic Lumix DMC-3D1 & Pentax K-7. The whole galleries are provided at Panasonic 3D1 Gallery & Pentax K-7 Gallery.

If you are planning to carry around your camera, you're going to have to take into account its weight and dimensions. The Panasonic 3D1 provides external dimensions of 108mm x 58mm x 24mm (4.3" x 2.3" x 0.9") with a weight of 193 grams (0.43 lbs) whilst the Pentax K-7 has dimensions of 131mm x 97mm x 73mm (5.2" x 3.8" x 2.9") having a weight of 750 grams (1.65 lbs).

Take into consideration, the weight of an ILC will differ dependant on the lens you are using during that time. The following is the front view over all size comparison of the 3D1 against the K-7.

Factoring in dimensions and weight, the portability grade of the 3D1 and K-7 is 93 and 60 respectively.

Quite often, its difficult to see the gap between sensor sizes purely by going over technical specs. The pic below will help give you a better sense of the sensor sizes in the 3D1 and K-7.

As you have seen, both of those cameras posses different megapixel count and different sensor sizes. The 3D1 with its tinier sensor will make shooting shallow DOF harder and the Pentax K-7 will offer you extra detail using its extra 3 Megapixels. Greater resolution will also let you crop images somewhat more aggressively. The younger 3D1 is going to have a benefit when it comes to sensor technology.
