The SX40 HS was announced 3 years earlier than the GM1 which is quite a big gap as far as technology is concerned. Both of these cameras come with different body type with the Canon SX40 HS being a SLR-like (bridge) camera and the Panasonic GM1 being a Rangefinder-style mirrorless camera.

Before going in to a in depth comparison, below is a quick view of how the SX40 HS scores against the GM1 in relation to portability, imaging, features and an overall score.

Don't forget, the weight of an Interchangeable Lens Camera will differ dependant on the lens you use at that time. Following is the front view measurement comparison of the SX40 HS against the GM1.

Using dimensions and weight, the portability rating of the SX40 HS and GM1 is 64 and 93 respectively.

More often than not, its difficult to imagine the contrast between sensor sizes purely by reviewing technical specs. The picture underneath might give you a far better sense of the sensor measurements in the SX40 HS and GM1.

As you have seen, both cameras have got different resolutions and different sensor sizes. The SX40 HS with its tinier sensor is going to make achieving bokeh tougher and the Panasonic GM1 will deliver extra detail with its extra 4 Megapixels. Greater resolution will allow you to crop images much more aggressively. The more aged SX40 HS is going to be behind when it comes to sensor technology.
