Ricoh WG-4 vs Sigma SD1

Below, we are analyzing the Ricoh WG-4 and Sigma SD1, one is a Waterproof and the other is a Advanced DSLR by manufacturers Ricoh and Sigma. The resolution of the WG-4 (16MP) and the SD1 (15MP) is very comparable but the WG-4 (1/2.3") and SD1 (APS-C) feature different sensor measurements.

The WG-4 was announced 3 years after the SD1 which is a fairly sizable gap as far as camera tech is concerned. The two cameras come with different body type with the Ricoh WG-4 being a Compact camera and the Sigma SD1 being a Mid-size SLR camera.

Before delving straight into a full comparison, below is a simple summation of how the WG-4 grades versus the SD1 for portability, imaging, features and an overall mark.

Here is a sample of the gallery pics for Ricoh WG-4 and Sigma SD1. The whole galleries are available at Ricoh WG-4 Gallery and Sigma SD1 Gallery.

For those who are going to travel with your camera frequently, you will have to take into account its weight and measurements. The Ricoh WG-4 provides outer dimensions of 124mm x 64mm x 33mm (4.9" x 2.5" x 1.3") and a weight of 230 grams (0.51 lbs) and the Sigma SD1 has proportions of 146mm x 113mm x 80mm (5.7" x 4.4" x 3.1") and a weight of n/a grams (0.00 lbs).

Do not forget, the weight of an Interchangeable Lens Camera will vary based on the lens you choose at the time. Underneath is the front view overall size comparison of the WG-4 against the SD1.

Using size and weight, the portability score of the WG-4 and SD1 is 90 and 77 respectively.

In many cases, it can be tough to visualize the gap in sensor dimensions simply by going through technical specs. The pic here may give you a greater sense of the sensor sizes in the WG-4 and SD1.

As you have seen, both of the cameras posses different megapixel count and different sensor dimensions. The WG-4 with its smaller sensor is going to make shooting shallow DOF more challenging and the Ricoh WG-4 will show extra detail with its extra 1MP. Greater resolution will allow you to crop images somewhat more aggressively. The younger WG-4 should have a benefit when it comes to sensor technology.
