Howzit - The SX30 has been out for a while, now, so CHDK for it should be available soon. That will give you RAW, which even in a P&S with a 1/2.3 sensor, has more information, so more adjustment leeway, for PP. It might also lift the 1.3fps Continuous Shooting speed, hopefully.
It's a bit odd that Canon didn't put RAW ability in the SX30 - with the exception of Nikon's P100, most Bridge Cameras now have RAW. (It isn't that Canon "can't do it" - the SX1 has RAW and 4fps.)
That does "make a difference", though of course a small-sensor P&S RAW can't be compared with even a crop-body 12+ times larger sensor.
I have a Canon SX10 and a Fuji HS10 - and while the HS10 does "quite adequate snaps" in JPEG, the SX10 when saving at the Superfine option, beats it on IQ. The "detail in shadows" is particularly noticeable.
The HS10's "Fine" JPEGs (they're both 10Mpix sensors) - are very similar to the SX10's "mid" option, "Fine". Both save at about 2.5-5MB file size. However, in the "less JPEG artifacting" Superfine, the SX10 does JPEGs up to 8-9MB.
Note that CHDK for SX30 will probably return the Superfine JPEG level, as it does with the SX20 - and that's very worthwhile having.
With the HS10, particularly at longer zoom levels, I tend to have it on a tripod for better results, and use RAW + JPEG. It does have 4-way Stabilising - but at long zoom, the tiniest movement makes the difference between a sharp clearly detailed image, and a 'snapshot'.
Compared with the SX10, the HS10 isn't an easy camera to use and get good results, but once you learn how to "tell it what to do", results are good. It does have a very good Manual mode, and excellent MF (which works in all modes, including Auto.)
It is also very good at higher ISOs - ISO-1600 is still in "normal images" range, with little "cleaning-up" to do - and in really low light, images at ISOs 3200 and 6400 are "usable" - more for onscreen and sharing - if the display size is reduced.
However, while the HS10 does both Std and Full HD, as the "controls" are "Auto" - limiting either to short clips is best - the SX30 beats it hands-down on Video Control!
