Olympus E-P1 vs Pentax Efina

Let's take a closer look at the Olympus E-P1 versus Pentax Efina, one being a Entry-Level Mirrorless and the other is a Ultracompact by rivals Olympus and Pentax. The sensor resolution of the E-P1 (12MP) and the Efina (14MP) is fairly similar but the E-P1 (Four Thirds) and Efina (1/2.3") have totally different sensor sizing.

The E-P1 was manufactured 4 years prior to the Efina and that is quite a big gap as far as technology is concerned. Each of the cameras feature different body design with the Olympus E-P1 being a Rangefinder-style mirrorless camera and the Pentax Efina being a Ultracompact camera.

Before delving into a in-depth comparison, here is a brief synopsis of how the E-P1 grades versus the Efina in regards to portability, imaging, features and an overall rating.

This is a sample of the gallery pictures for Olympus PEN E-P1 and Pentax Efina. The entire galleries are provided at Olympus E-P1 Gallery and Pentax Efina Gallery.

When you are going to carry your camera frequently, you will want to take into account its weight and volume. The Olympus E-P1 features external dimensions of 121mm x 70mm x 36mm (4.8" x 2.8" x 1.4") with a weight of 355 grams (0.78 lbs) and the Pentax Efina has sizing of 87mm x 54mm x 21mm (3.4" x 2.1" x 0.8") accompanied by a weight of 91 grams (0.20 lbs).

Do not forget, the weight of an Interchangeable Lens Camera will vary depending on the lens you are utilising during that time. Underneath is a front view overall size comparison of the E-P1 against the Efina.

Taking into consideration dimensions and weight, the portability grade of the E-P1 and Efina is 86 and 97 respectively.

Quite often, it is hard to see the difference between sensor sizing merely by reading specifications. The graphic below may provide you a better sense of the sensor dimensions in the E-P1 and Efina.

Plainly, both cameras feature different resolutions and different sensor sizing. The E-P1 featuring a larger sensor will make getting shallow depth of field less difficult and the Pentax Efina will offer extra detail due to its extra 2 Megapixels. Greater resolution will let you crop photos way more aggressively. The older E-P1 is going to be behind in sensor technology.
