The K100D was revealed 6 years before the A65 which is quite a big difference as far as technology is concerned. Both of these cameras feature the same body design (Compact SLR).

Before getting right into a in depth comparison, here is a short view of how the K100D scores vs the A65 in the way of portability, imaging, features and an overall score.

This is a sample of the gallery pictures for Pentax K100D & Sony SLT-A65. The full galleries are viewable at Pentax K100D Gallery & Sony A65 Gallery.

If you're intending to carry around your camera frequently, you have to consider its weight and dimensions.

Normally, it is very difficult to visualize the gap between sensor sizes purely by reading technical specs. The pic here may provide you a much better sense of the sensor measurements in the K100D and A65.

As you have seen, both of these cameras feature the identical sensor size but different megapixels. You can anticipate the Sony A65 to offer you more detail because of its extra 18 Megapixels. Greater resolution can also allow you to crop photos way more aggressively. The more aged K100D is going to be disadvantaged when it comes to sensor innovation.
