Panasonic 3D1 vs Panasonic GM1

Here is a in-depth comparison of the Panasonic 3D1 versus Panasonic GM1, one being a Small Sensor Compact and the latter is a Entry-Level Mirrorless and both are created by Panasonic. There exists a sizeable gap between the image resolutions of the 3D1 (12MP) and GM1 (16MP) and the 3D1 (1/2.3") and GM1 (Four Thirds) offer totally different sensor measurements.

The 3D1 was unveiled 3 years earlier than the GM1 and that is quite a large gap as far as technology is concerned. Both of these cameras feature different body design with the Panasonic 3D1 being a Compact camera and the Panasonic GM1 being a Rangefinder-style mirrorless camera.

Before delving into a in-depth comparison, here is a simple overview of how the 3D1 grades vs the GM1 with respect to portability, imaging, features and an overall rating.

If you're going to carry your camera, you will want to factor in its weight and volume. The Panasonic 3D1 offers physical measurements 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 Panasonic GM1 has sizing of 99mm x 55mm x 30mm (3.9" x 2.2" x 1.2") having a weight of 204 grams (0.45 lbs).

Remember, the weight of an Interchangeable Lens Camera will vary based on the lens you choose at that time. Below is a front view physical size comparison of the 3D1 compared to the GM1.

Taking into account dimensions and weight, the portability score of the 3D1 and GM1 is 93 and 93 respectively.

Sometimes, it is difficult to visualise the contrast between sensor sizing simply by reviewing technical specs. The visual below will provide you a more clear sense of the sensor sizing in the 3D1 and GM1.

As you have seen, both the cameras feature different megapixels and different sensor sizing. The 3D1 with its tinier sensor will make achieving shallow DOF tougher and the Panasonic GM1 will deliver greater detail having an extra 4 Megapixels. Higher resolution can also let you crop pictures way more aggressively. The older 3D1 is going to be behind in sensor innovation.
