Panasonic G100 vs Sony A7R

Lets take a deeper look at the Panasonic G100 and Sony A7R, one being a Entry-Level Mirrorless and the other is a Pro Mirrorless by brands Panasonic and Sony. There exists a crucial gap among the sensor resolutions of the G100 (20MP) and A7R (36MP) and the G100 (Four Thirds) and A7R (Full frame) posses different sensor sizes.

The G100 was announced 6 years later than the A7R and that is a fairly serious gap as far as camera technology is concerned. Both of these cameras have the same body design (SLR-style mirrorless).

Before diving into a in-depth comparison, here is a simple overview of how the G100 matches up vs the A7R in relation to portability, imaging, features and an overall rating.

Here is a sample of the gallery pictures for Panasonic Lumix DC-G100 and Sony Alpha A7R. The whole galleries are viewable at Panasonic G100 Gallery and Sony A7R Gallery.

When you are going to carry your camera often, you're going to have to factor its weight and proportions. The Panasonic G100 features physical measurements of 116mm x 83mm x 54mm (4.6" x 3.3" x 2.1") with a weight of 352 grams (0.78 lbs) whilst the Sony A7R has measurements of 127mm x 94mm x 48mm (5.0" x 3.7" x 1.9") accompanied by a weight of 465 grams (1.03 lbs).

Remember, the weight of an Interchangeable Lens Camera will vary dependant on the lens you are employing at that time. Here is a front view size comparison of the G100 against the A7R.

Using dimensions and weight, the portability score of the G100 and A7R is 81 and 78 respectively.

Sometimes, it's hard to imagine the contrast in sensor sizing purely by looking through technical specs. The graphic here will provide you a far better sense of the sensor sizing in the G100 and A7R.

As you have seen, both of these cameras have different megapixel count and different sensor sizing. The G100 with its smaller sensor is going to make getting shallow depth of field harder and the Sony A7R will result in more detail with its extra 16MP. Greater resolution can also help you crop photos a bit more aggressively. The more recent G100 should have an edge when it comes to sensor tech.
