The TG-4 was unveiled 5 years after the A850 which is a fairly significant gap as far as camera technology is concerned. Both of these cameras feature different body design with the Olympus TG-4 being a Compact camera and the Sony A850 being a Mid-size SLR camera.

Before we go right into a comprehensive comparison, here is a simple summary of how the TG-4 scores versus the A850 with regards to portability, imaging, features and an overall score.

The following is a sample of the gallery pictures for Olympus Tough TG-4 and Sony Alpha DSLR-A850. The full galleries are available at Olympus TG-4 Gallery and Sony A850 Gallery.

Sometimes, it is hard to visualise the contrast in sensor sizes purely by looking through a spec sheet. The picture here may provide you a much better sense of the sensor measurements in the TG-4 and A850.

Clearly, each of the cameras feature different megapixel count and different sensor sizes. The TG-4 using its smaller sensor will make getting shallower depth of field more challenging and the Sony A850 will result in extra detail having an extra 9MP. Greater resolution can also let you crop photos way more aggressively. The newer TG-4 is going to have an advantage with regard to sensor tech.
