Pentax S1 vs Sony NEX-5T

Let's look more closely at the Pentax S1 vs Sony NEX-5T, former is a Small Sensor Compact while the other is a Entry-Level Mirrorless by companies Pentax and Sony. The resolution of the S1 (14MP) and the NEX-5T (16MP) is fairly well matched but the S1 (1/2.3") and NEX-5T (APS-C) offer different sensor sizes.

The S1 was released 3 years before the NEX-5T which is quite a serious difference as far as technology is concerned. The two cameras feature different body design with the Pentax S1 being a Compact camera and the Sony NEX-5T being a Rangefinder-style mirrorless camera.

Before going into a step-by-step comparison, here is a short highlight of how the S1 grades versus the NEX-5T with respect to portability, imaging, features and an overall mark.

Below is a sample of the gallery pictures for Pentax Optio S1 & Sony Alpha NEX-5T. The complete galleries are available at Pentax S1 Gallery & Sony NEX-5T Gallery.

When you are looking to travel with your camera often, you're going to have to think about its weight and volume. The Pentax S1 has got outside measurements of 114mm x 58mm x 28mm (4.5" x 2.3" x 1.1") and a weight of 157 grams (0.35 lbs) while the Sony NEX-5T has sizing of 111mm x 59mm x 39mm (4.4" x 2.3" x 1.5") and a weight of 276 grams (0.61 lbs).

Don't forget, the weight of an ILC will vary based on the lens you are using during that time. Underneath is a front view sizing comparison of the S1 compared to the NEX-5T.

Taking into consideration dimensions and weight, the portability rating of the S1 and NEX-5T is 93 and 89 respectively.

Quite often, its difficult to imagine the difference between sensor dimensions purely by looking at a spec sheet. The picture here may provide you a better sense of the sensor measurements in the S1 and NEX-5T.

Clearly, the two cameras feature different megapixels and different sensor dimensions. The S1 featuring a tinier sensor is going to make shooting shallower DOF harder and the Sony NEX-5T will resolve extra detail as a result of its extra 2MP. Greater resolution will also help you crop pics way more aggressively. The more aged S1 is going to be disadvantaged when it comes to sensor technology.
