I bought an SX-1 before it was announced in the US. I paid what I consider to be a fair price for it ($570 or so). Yes, that’s $200 or so more than the SX-10 without “a lot of” new features. I see it as giving me good video quality with a lot of flexibility with the option for HD in addition to serviceable image quality in good light (or with my 550EX flash). I don’t shoot HD clips all that often, but when I want it, VGA is a poor substitute. Would I have preferred something more like 6 MP and, say, a 20-400 equivalent zoom range (or even 20-300)? Absolutely. But my old S3 can’t use my flash and needs an adapter lens to get below 36 mm equivalent, both of which are significant restrictions. The SX-1 gives me a good camcorder and a good camera in one compact (I’m 6′5″, and if I say it’s compact, it’s compact!) package.

I also have a 20D with a decent set of lenses — 3 zooms (Sigma 12-24, Canon 28-135, and Canon 70-300) and some primes (28, 50 — the old style f/1.8, 85, and 200L). No, those zooms are not the best image quality (although the 70-300 makes a pretty good run at it, compared to the execrable 75-300 I previously had). When I want image quality, or low light performance, I use the 20D. Eventually I’ll upgrade, to what, I haven’t decided (I’m even thinking a used 5D mk I, potentially).

Personally, I’m not terribly enamored of the 5D mkII as a video camera (even ignoring the price, and I’m not really a pro). While the image quality runs rings around the SX-1, the 5D doesn’t strike me as a particularly good form factor for shooting video on the fly, which is my shooting style. Having a wide zoom range is more important for video, since you can’t change lenses in the middle of a clip, and the power zoom is smoother than manual zoom. The 5D also doesn’t have a stereo mike, and the USM on the SX1 is much quieter than that on even the 85 f/1.8 and 200 f/2.8 — again, completely irrelevant for still photography, but possibly relevant when shooting video with an on-camera mike.

Would I use the SX-1 at a wedding? Yes, for video clips or as a backup. An HD clip of the groom breaking the glass at a Jewish wedding, quickly zooming way out to catch a shot of the couple, would be well worth it even if the quality’s not as good technically as the 5D. Likewise, throwing the bouquet or the garter if there’s enough light. Would I use it for formal shots? No, but that’s what the 20D is for. I think DPR missed the boat on this — HD video in a compact camera *is* a disruptive feature.

I like image quality also, but I also like the shot I get vs. the one I don’t, and I also don’t have an unlimited budget for a hobby. The SX-1 fills a lot of niches very well, and I think Canon made a good set of tradeoffs.

Google this, Leica S1

THAT is ugly, the one and only camera that totally (bleep)ed up Leica.

I can assure you that 85% of Canon customers (point & shooters and DSLR newbies) don’t even know what’s the difference between CCD and CMOS sensors, all they care about is owning a camera that take pictures, that’s it, simple.

(10% are gearheads and 5% are full time photographers, the last 15% knows the difference)

on the other hand, it’s got 1080/30p and stereo sound, which somehow the 500D isn’t capable of.
