Sony A7S vs Sony T90

Below, we will be reviewing the Sony A7S vs Sony T90, one is a Pro Mirrorless and the latter is a Ultracompact and they are both built by Sony. The image resolution of the A7S (12MP) and the T90 (12MP) is relatively well matched but the A7S (Full frame) and T90 (1/2.3") use different sensor measurements.

The A7S was released 5 years after the T90 which is quite a serious gap as far as technology is concerned. Both of these cameras come with different body type with the Sony A7S being a SLR-style mirrorless camera and the Sony T90 being a Ultracompact camera.

Before going straight into a more detailed comparison, below is a simple synopsis of how the A7S scores versus the T90 with regard to portability, imaging, features and an overall mark.

Here is a preview of the gallery photos for Sony Alpha A7S and Sony Cyber-shot DSC-T90. The complete galleries are viewable at Sony A7S Gallery and Sony T90 Gallery.

When you are going to travel with your camera regularly, you need to factor its weight and proportions. The Sony A7S features outside measurements of 127mm x 94mm x 48mm (5.0" x 3.7" x 1.9") and a weight of 489 grams (1.08 lbs) while the Sony T90 has measurements of 94mm x 57mm x 15mm (3.7" x 2.2" x 0.6") along with a weight of 148 grams (0.33 lbs).

Remember, the weight of an Interchangeable Lens Camera will vary based on the lens you are utilising at that moment. Following is the front view scale comparison of the A7S vs the T90.

Considering dimensions and weight, the portability grade of the A7S and T90 is 77 and 96 respectively.

Sometimes, it is difficult to visualize the difference between sensor dimensions simply by reading through specs. The pic below should provide you a more clear sense of the sensor sizing in the A7S and T90.

All in all, both of those cameras posses the exact same megapixel count albeit different sensor dimensions. The A7S uses the bigger sensor which should make getting shallow DOF easier. The fresher A7S should have an advantage in sensor tech.
