Yes please. Go and photograph those white swans again. I'd like to see how the HS handles that as compared to the SX.
Try the camera out in the toughest situations you can find. I'd really like to know if the HS50 is a viable option for me. I'm not going to compare it to an APS-C DSLR... but I think sensor and lens technology is finally reaching the point where a camera like this is a genuine option.
