Olympus TG-4 vs Sony NEX-7

Here, we will be contrasting the Olympus TG-4 versus Sony NEX-7, one being a Waterproof and the latter is a Advanced Mirrorless by competitors Olympus and Sony. There is a significant difference between the image resolutions of the TG-4 (16MP) and NEX-7 (24MP) and the TG-4 (1/2.3") and NEX-7 (APS-C) provide totally different sensor measurements.

The TG-4 was released 3 years later than the NEX-7 and that is quite a sizable gap as far as tech is concerned. Both of these cameras feature different body design with the Olympus TG-4 being a Compact camera and the Sony NEX-7 being a Rangefinder-style mirrorless camera.

Before getting straight to a full comparison, here is a short highlight of how the TG-4 matches up versus the NEX-7 in the way of portability, imaging, features and an overall grade.

Here is a preview of the gallery images for Olympus Tough TG-4 and Sony Alpha NEX-7. The complete galleries are provided at Olympus TG-4 Gallery and Sony NEX-7 Gallery.

If you're aiming to lug around your camera frequently, you should consider its weight and measurements. The Olympus TG-4 enjoys outer measurements of 112mm x 66mm x 31mm (4.4" x 2.6" x 1.2") along with a weight of 247 grams (0.54 lbs) whilst the Sony NEX-7 has proportions of 120mm x 67mm x 43mm (4.7" x 2.6" x 1.7") accompanied by a weight of 400 grams (0.88 lbs).

Always remember, the weight of an Interchangeable Lens Camera will differ based on the lens you are working with at that moment. Below is a front view overall size comparison of the TG-4 against the NEX-7.

Taking into consideration size and weight, the portability rating of the TG-4 and NEX-7 is 90 and 84 respectively.

Often, it can be tough to envision the difference between sensor measurements purely by reading technical specs. The photograph underneath may offer you a clearer sense of the sensor sizing in the TG-4 and NEX-7.

As you have seen, both of those cameras feature different megapixels and different sensor measurements. The TG-4 because of its tinier sensor will make achieving shallower DOF trickier and the Sony NEX-7 will deliver greater detail as a result of its extra 8 Megapixels. Higher resolution can also enable you to crop shots way more aggressively. The more modern TG-4 will have a benefit with regard to sensor tech.
