Pentax XG-1 vs Sony G3

Here, we are analyzing the Pentax XG-1 and Sony G3, one being a Small Sensor Superzoom and the other is a Small Sensor Compact by companies Pentax and Sony. There is a huge difference between the image resolutions of the XG-1 (16MP) and G3 (10MP) but both cameras provide the identical sensor dimensions (1/2.3").

The XG-1 was manufactured 5 years later than the G3 and that is quite a significant gap as far as tech is concerned. Both the cameras feature different body design with the Pentax XG-1 being a SLR-like (bridge) camera and the Sony G3 being a Compact camera.

Before delving right into a more detailed comparison, here is a brief view of how the XG-1 matches up against the G3 in regards to portability, imaging, features and an overall grade.

In case you're looking to lug around your camera frequently, you are going to need to take into account its weight and volume. The Pentax XG-1 has got exterior measurements of 119mm x 89mm x 98mm (4.7" x 3.5" x 3.9") along with a weight of 567 grams (1.25 lbs) whilst the Sony G3 has sizing of 97mm x 59mm x 22mm (3.8" x 2.3" x 0.9") accompanied by a weight of 185 grams (0.41 lbs).

Always remember, the weight of an Interchangeable Lens Camera will change dependant on the lens you have attached during that time. Underneath is a front view dimension comparison of the XG-1 against the G3.

Factoring in size and weight, the portability grade of the XG-1 and G3 is 66 and 94 respectively.

Oftentimes, it is very difficult to picture the gap between sensor measurements purely by looking at a spec sheet. The photograph here should give you a far better sense of the sensor sizing in the XG-1 and G3.

Clearly, each of these cameras feature the identical sensor size but different megapixels. You should anticipate the Pentax XG-1 to give more detail due to its extra 6 Megapixels. Greater resolution will also let you crop pics way more aggressively. The more recent XG-1 should have an advantage with regard to sensor tech.
