OM System OM-5 vs Sony A7R Sensor Comparison

In many cases, it can be difficult to see the contrast between sensor measurements purely by looking at a spec sheet. The photograph below might offer you a far better sense of the sensor measurements in the OM System OM-5 and A7R.

As you can see, the two cameras come with different megapixels and different sensor measurements. The OM System OM-5 due to its tinier sensor will make shooting bokeh trickier and the Sony A7R will resolve more detail due to its extra 16 Megapixels. Greater resolution can also make it easier to crop photos a good deal more aggressively. The newer OM System OM-5 is going to have a benefit in sensor technology.
