EvanK - Before I bought the HS10 - and while waiting for Fuji's firmware updates to fix the initial strange problems, the 24-30mm JPEG distortion, the JPEG 'Fine' smearing, etc - both fixed at 1.02 - I did about 3 months Hmmm-ing and Hahh-ing over 3 cameras - HS10, P100, and Pentax K-X.
I already had some K-mount and M42 lenses for Pentax. And the HS10 and P100 use the same BSI sensor.
The K-X dropped out, because I wasn't at all sure I knew enough to use a DSLR properly - and the K-X has its focus-screen and a couple of other "issues" - to be fixed in the next model, said Pentax.
A friend bought a P100, had it from Friday to Monday, and returned it. On that Saturday afternoon I "shared" the P100 with that friend, for several hours, swapping it for my Canon SX10, and each trying the other camera. Apart from 6x more zoom, the SX10 eats the P100 for handling and JPEG quality.
The friend "just loved" the SX10 and the vast number of settings and adjustments. When she took the P100 back, she swapped it for an SX20.
Which doesn't have the SX10's Superfine JPEGs, and a few other things. She'll swap the 15-months newer SX20 + $50.00 for my SX10.... Ahh, nope...!
The P100 might be a little better than the HS10 on Video handling, but not a lot. And on low light - and higher ISO..., ah - try the P100 at ISO 1600-3200-6400.... Ooops! Try it on Fast Continuous - the HS10 is all over it! As for the P100 doing RAW and RAW + JPEG at any speed - no, it doesn't do RAW at all.
Try the P100 in Manual Mode... Ohhh..., deahhh! The HS10 is very good indeed in Manual, including handheld. . And the P100 on Manual Focus...? Rather scatty... HS10 on MF - push preset, and move the barrel Focus Ring a couple of mm either way - while holding the shutter button half-down (does nothing in MF, but you're ready to no-delay shoot) - focus centred, and shoot. Fastest and most accurate MF I've ever tried on a P&S...
How many P&S cameras do folk use hand-held, Manual, MF, and when "focus-on" - fire up to 7 frames at over 12fps? Actually - that's "too fast" - there's almost no variation between frames, unless the target is moving very quickly. The 7fps is more useful, mostly, or 5 for more 'time coverage'.
RAW and RAW + JPEG are 5fps or 3fps. The up to 12fps+ is JPEG only.
Unless folk have a high priority for excellent Video and Controls - in which case it's SX30 "hands-down" - the keener-user comp seems to be between the Panasonic FZ100 and the Fuji HS10.
The "Pentax K-X that didn't" will become the K-R that does - when Sydney prices on K-Rs come down to sanity-range.
And it isn't Pentax because I don't like Canon - the SX10 is one heckuva-good advert for Canon! And a nice Canon DSLR and a shelf-full of superb L-lenses do waste a lot of my dreaming-time...!
But no, you don't do that on a pension... So a fairly good Pentax body, a Sigma 17-70mm as walk-around - and my K-mounts and M42s to learn-into. With an "unused, as new" (gift from my landlord) - SMC Takumar Asahi-Pentax 55mm f/1.8 - I'll do that "nice bokeh" thing yet...!
Lotsa-fun learning-into those "ancient treasures"...
Dave.
