Sony A3000 vs Sony A7R

Let's look a little more in depth at the Sony A3000 and Sony A7R, one is a Entry-Level Mirrorless and the other is a Pro Mirrorless and they are both manufactured by Sony. There exists a crucial gap among the image resolutions of the A3000 (20MP) and A7R (36MP) and the A3000 (APS-C) and A7R (Full frame) have different sensor sizes.

The A3000 was revealed 5 months earlier than the A7R so they are of a similar generation. Each of the cameras have the same body design (SLR-style mirrorless).

Before we go straight to a more detailed comparison, here is a quick overview of how the A3000 matches up vs the A7R with respect to portability, imaging, features and an overall mark.

Below is a sample of the gallery pics for Sony Alpha A3000 and Sony Alpha A7R. The full galleries are viewable at Sony A3000 Gallery and Sony A7R Gallery.

If you are intending to travel with your camera regularly, you have to consider its weight and measurements. The Sony A3000 has got outer dimensions of 128mm x 91mm x 85mm (5.0" x 3.6" x 3.3") having a weight of 411 grams (0.91 lbs) whilst the Sony A7R has proportions of 127mm x 94mm x 48mm (5.0" x 3.7" x 1.9") accompanied by a weight of 465 grams (1.03 lbs).

Do not forget, the weight of an Interchangeable Lens Camera will change depending on the lens you choose during that time. Below is a front view measurements comparison of the A3000 versus the A7R.

Normally, it can be tough to picture the difference in sensor dimensions purely by going through a spec sheet. The image below will give you a stronger sense of the sensor dimensions in the A3000 and A7R.

Clearly, both the cameras provide different resolutions and different sensor dimensions. The A3000 with its smaller sensor is going to make getting shallower DOF more difficult and the Sony A7R will produce extra detail because of its extra 16MP. Greater resolution will also enable you to crop pics more aggressively.
