Panasonic FZ100 vs Panasonic GM1

Its time to look much closer at the Panasonic FZ100 versus Panasonic GM1, one being a Small Sensor Superzoom and the other is a Entry-Level Mirrorless and both are designed by Panasonic. The image resolution of the FZ100 (14MP) and the GM1 (16MP) is fairly similar but the FZ100 (1/2.3") and GM1 (Four Thirds) feature totally different sensor size.

The FZ100 was unveiled 4 years earlier than the GM1 and that is quite a serious gap as far as tech is concerned. Both of these cameras offer different body type with the Panasonic FZ100 being a SLR-like (bridge) camera and the Panasonic GM1 being a Rangefinder-style mirrorless camera.

Before we go in to a full comparison, below is a simple summation of how the FZ100 matches up against the GM1 with respect to portability, imaging, features and an overall grade.

Here is a sample of the gallery pictures for Panasonic Lumix DMC-FZ100 and Panasonic Lumix DMC-GM1. The full galleries are provided at Panasonic FZ100 Gallery and Panasonic GM1 Gallery.

In many cases, its hard to visualise the difference between sensor measurements just by reviewing technical specs. The graphic underneath will provide you a clearer sense of the sensor dimensions in the FZ100 and GM1.

As you have seen, both of those cameras offer different megapixel count and different sensor measurements. The FZ100 having a tinier sensor will make getting bokeh harder and the Panasonic GM1 will offer you more detail having an extra 2 Megapixels. Greater resolution will allow you to crop photos a little more aggressively. The older FZ100 is going to be behind when it comes to sensor innovation.
