Canon 7D vs Canon M3

On this page, we are looking at the Canon 7D versus Canon M3, former being a Advanced DSLR while the other is a Entry-Level Mirrorless and they are both produced by Canon. There is a considerable difference among the resolutions of the 7D (18MP) and M3 (24MP) but both cameras boast the same sensor dimensions (APS-C).

The 7D was announced 6 years prior to the M3 and that is a fairly large difference as far as camera tech is concerned. Both the cameras have different body design with the Canon 7D being a Mid-size SLR camera and the Canon M3 being a Rangefinder-style mirrorless camera.

Before going right into a full comparison, here is a short synopsis of how the 7D grades against the M3 when it comes to portability, imaging, features and an overall rating.

The following is a sample of the gallery pics for Canon EOS 7D & Canon EOS M3. The whole galleries are available at Canon 7D Gallery & Canon M3 Gallery.

When you are going to carry your camera often, you will need to consider its weight and dimensions. The Canon 7D has got physical measurements of 148mm x 111mm x 74mm (5.8" x 4.4" x 2.9") and a weight of 860 grams (1.90 lbs) and the Canon M3 has dimensions of 111mm x 68mm x 44mm (4.4" x 2.7" x 1.7") and a weight of 366 grams (0.81 lbs).

Taking into consideration size and weight, the portability rating of the 7D and M3 is 56 and 85 respectively.

Often, it is very tough to visualise the contrast in sensor sizing just by looking through a spec sheet. The graphic below may offer you a much better sense of the sensor measurements in the 7D and M3.

As you can see, the two cameras provide the same sensor dimensions but not the same resolution. You can expect to see the Canon M3 to result in greater detail with its extra 6 Megapixels. Greater resolution will let you crop images more aggressively. The older 7D will be disadvantaged with regard to sensor tech.
