Panasonic GM1 vs Sony a5100

Let's take a deeper look at the Panasonic GM1 versus Sony a5100, both Entry-Level Mirrorless digital cameras by manufacturers Panasonic and Sony. There exists a significant gap between the resolutions of the GM1 (16MP) and a5100 (24MP) and the GM1 (Four Thirds) and a5100 (APS-C) provide totally different sensor size.

The GM1 was released 8 months earlier than the a5100 and they are of a similar generation. Each of the cameras have the same body design (Rangefinder-style mirrorless).

Before going straight to a comprehensive comparison, here is a quick summary of how the GM1 grades against the a5100 for portability, imaging, features and an overall score.

The following is a sample of the gallery pics for Panasonic Lumix DMC-GM1 and Sony Alpha a5100. The complete galleries are viewable at Panasonic GM1 Gallery and Sony a5100 Gallery.

For anybody who is intending to carry around your camera frequently, you will want to consider its weight and measurements.

Typically, it is hard to see the contrast between sensor sizes only by checking specifications. The pic underneath may give you a stronger sense of the sensor measurements in the GM1 and a5100.

Plainly, the 2 cameras provide different resolutions and different sensor sizes. The GM1 due to its tinier sensor will make achieving shallow depth of field more difficult and the Sony a5100 will give more detail as a result of its extra 8 Megapixels. Greater resolution will also let you crop images more aggressively. The more aged GM1 is going to be disadvantaged with regard to sensor technology.
