Does the Canon SX1 produce better quality images than the Canon SX10?

Two different cameras have recently replaced the Canon PowerShot S5 IS. They are the PowerShot SX1 IS and PowerShot SX10 IS. The SX1 has a CMOS sensor, which allows it to do 4 frames per second continuous shooting, and full HD video. My question is if, in addition to these advantages, the SX1 is also produces better quality images? Or are its images possibly worse than the SX10's?

The SX10.
It uses a CCD sensor of the same size of the SX1's CMOS sensor. CCDs produce better uniformity and produce more pixels per inch on the sensor itself. CCDs provide more contrast, higher shutter speed capability, higher dynamic range, higher fill capacity and very good anti bloom characteristics.

Asker's Rating:
• This answers the question in principle, as a CCD sensor (used by the SX10) has certain advantages over a CMOS sensor (used by the SX1). However, I think I'll have to wait for a comparative review to find out if in actual practice the SX10 produces better images than then SX1.

Thank you for the very informed response. So, in principle, the SX10 should provide better images than the SX1. (I had hoped it might be the other way around!)

one place to find this out is DPREVIEW.com
this site is dedicated to camera reviews.
also- beware of small cameras with high megapixel counts.
Anything beyond 10 mp in a small non - slr camera is a waste and may make poorer images in low light.

DPREVIEW has not yet reviewed the SX1, which is why I'm asking this question here. While it is certainly generally true that one should beware of small sensors (not cameras) with high megapixel counts the SX10 and SX1 are by far not the worst examples of this. My question is not about the strengths and limitations of this type of camera, but whether the SX1 produces better images than the SX10.

The SX110 is a fine camera but belongs to a completely different class. It has 10x optical zoom, compared to 20x zoom in the SX10 and SX1. My question is not about what other good cameras are out there, but whether the SX1 produces better images than the SX10.

I have not yet seen a real review of the SX1. As far as I know it won't be marketed in the US, though you can get one on eBay. I know someone with one, but he doesn't have the means to make a comparison between it and the SX10.

My educated guess is that the quality at low ISO will be indistinguishable or nearly so. They use the same lens, so this is an obvious statement, perhaps.

At high ISOs, there could be a difference in quality. My bet would be on the CMOS chip slightly outperforming the CCD, but it can't be known yet.

I will also note, as an experienced photographer, that the difference likely won't be worth talking about when it comes to making a print. DPReview and its ilk are good for looking at small differences between cameras, but all too frequently, some people agonize over what in reality are things that won't affect their picture as much as they think it will.

Another note is that while the SX10, and SX1 will outperform many other point and shoot cameras, they're inherently limited by their small sensor size, and you can get significantly better quality in many circumstances with an SLR, if you have the skill and equipment to do so. The biggest difference between the SX110 and SX10, for example, is the amount of zoom. Otherwise, they will produce remarkably similar results. The SX10's lens is probably sharper. It might have a bit less noise at high ISOs. But what matters in the end is the print, and you might not be able to tell the difference between 8x10s printed with the different cameras. It's not that having more zoom isn't useful, it's that in and of itself, it won't actually improve your photographic results.

Looking at stuff at 100% on a computer screen is like looking at a 40" print. There are a lot of things you'll notice on the screen that isn't visible in a print unless you're looking at it under a loupe... nor are most of these differences visible in images sized for use on the internet.

I have also not seen a proper review of the SX1 yet - hopefully somebody will do one soon! Even better would be a head-to-head comparison between the SX10 and SX1. I own an S5 - the predecessor to these two cameras - which does produce some excellent results. However, I have become frustrated with its relatively limited dynamic range - e.g., it is hard to get good detail in a shady area under a tree without having nearby brightly lit areas over-exposed. I was hoping that maybe the CMOS sensor on the SX1 might fix that. (From the reviews I've seen it looks like the SX10, which uses a CCD sensor, suffers from essentially the same small-sensor limitations as the S5.) Looks like I'll have to go for an SLR after all, including all those bulky lenses...
