DSLRs have exceptional lenses with exceptional but large sensors, which means the zooms are modest (up to around ~600mm) So the really interesting long focal lenght cameras are the all-in-one superzoom cameras like the canon sx70hs and nikon p1000. They accomplish the high magnification by using a sort-of-good lens with a sort-of-good small sensor, achieving up to 3000mm "equivalent" zoom. Unfortunately, the "pro-sum…
The smaller cameras never really convjnced me as real DSLR replacements - they lacked the versatility and ergonomics of the DSLR and the smaller sensors meant more noise especially in dark scenes. The first camera that I use that has started being ok is the pixel phone cameras using night sight to improve overall resolution and detail.
One interesting thing about Olympus cameras, that they do have a lot of computational photography things described in the article:
- there is a "Live Composite" mode, which allows you to get those star trails, to do light painting, etc.
- there is build-in focus stacking, very useful for macro photography
- there is hi-res mode implemented with pixel (or rather sensor) shifting
- there is IBIS and digital image stabilization.
