Panasonic G3 vs Sony A7

Its time to take a more detailed look at the Panasonic G3 versus Sony A7, one being a Entry-Level Mirrorless and the latter is a Pro Mirrorless by manufacturers Panasonic and Sony. There exists a crucial gap between the image resolutions of the G3 (16MP) and A7 (24MP) and the G3 (Four Thirds) and A7 (Full frame) enjoy totally different sensor size.

Photography Glossary

The G3 was introduced 3 years before the A7 and that is quite a serious gap as far as technology is concerned. Each of the cameras offer the identical body type (SLR-style mirrorless).

Before diving through a in-depth comparison, below is a short synopsis of how the G3 matches up against the A7 in the way of portability, imaging, features and an overall rating.

Below is a preview of the gallery photos for Panasonic Lumix DMC-G3 and Sony Alpha A7. The whole galleries are provided at Panasonic G3 Gallery and Sony A7 Gallery.

When you are planning to carry your camera, you'll need to factor its weight and dimensions.

Normally, it's hard to see the difference between sensor sizing merely by looking at technical specs. The photograph underneath may provide you a greater sense of the sensor measurements in the G3 and A7.

As you have seen, both of those cameras enjoy different megapixel count and different sensor sizing. The G3 using its tinier sensor will make achieving shallow depth of field more difficult and the Sony A7 will resolve greater detail using its extra 8 Megapixels. Higher resolution will also enable you to crop photographs far more aggressively. The older G3 is going to be behind with regard to sensor tech.
