Nikon A vs Nikon A100

Let's take a closer look at the Nikon A and Nikon A100, one being a Large Sensor Compact and the latter is a Ultracompact and both are offered by Nikon. The sensor resolution of the A (16MP) and the A100 (20MP) is pretty comparable but the A (APS-C) and A100 (1/2.3") feature different sensor measurements.

The A was manufactured 3 years earlier than the A100 and that is a fairly sizable gap as far as camera technology is concerned. The two cameras come with different body type with the Nikon A being a Large Sensor Compact camera and the Nikon A100 being a Ultracompact camera.

Before delving through a more detailed comparison, below is a short introduction of how the A matches up against the A100 when considering portability, imaging, features and an overall rating.

The following is a preview of the gallery images for Nikon Coolpix A and Nikon Coolpix A100. The entire galleries are viewable at Nikon A Gallery and Nikon A100 Gallery.

In case you're planning to carry your camera often, you will want to factor in its weight and volume. The Nikon A has got external measurements of 111mm x 64mm x 40mm (4.4" x 2.5" x 1.6") accompanied by a weight of 299 grams (0.66 lbs) while the Nikon A100 has sizing of 95mm x 59mm x 20mm (3.7" x 2.3" x 0.8") along with a weight of 119 grams (0.26 lbs).

Quite often, it is very tough to picture the contrast in sensor sizing just by checking out a spec sheet. The visual below might provide you a more clear sense of the sensor measurements in the A and A100.

As you can see, each of the cameras have got different resolutions and different sensor sizing. The A because of its bigger sensor is going to make achieving shallower depth of field less difficult and the Nikon A100 will provide more detail due to its extra 4MP. Higher resolution will allow you to crop pictures much more aggressively. The older A will be disadvantaged with regard to sensor technology.
