SX20 IS / SX30 IS vs. SX1 IS re. image accuracy/clarity -- ??? I've seen multiple comments NEGATIVELY comparing the image quality of the super-zoom SX30IS vs. both the SX20IS (i.e. the model it's replacing) and the old S2IS (my own current, beloved but aging model) re. not trying to cram many more pixels (SX20's 12MP or SX30's 14MP, rarely really necessary) onto the same size sensor. However, I haven't spotted any comparison vs. the DPReview-recommended 2008 [intermediate] model, the SX1IS (which uses a 10MP CMOS sensor, rather than a CCD, and has the same zoom range as the SX20IS). Can anyone offer a personally side-by-side-tested perspective on truly equivalent [cropped] images?

I believe you (ranthon007) are operating under a false assumption. Regardless of what image size you choose to use, the actual physical pixels on the sensor must necessarily remain the size they are, and if that's too small to let in the ideal amount of light, well then you're stuck. I'm not sure whether smaller output sizes are done by rescaling or by simply using fewer of the pixels (i.e. not the whole sensor), but while you MAY be gaining some reduction of noise, there is NOT an actual increase of detail.(Anyone please correct me if any of the above is in at all incorrect!)

I have the SX1IS ad SX30IS. Going to sell one of them. I did a comparison of what I called final image quality.http://www.cameramike.com/cameramike/MEDI_1./Pages/SX30is_compare_SX1is.html Yes - RAW output is an advantage but when you reduce the noise of the SX30 image it is of equal or maybe better quality of the RAW SX1 image. Using my simple non technical setup. I did look at other setting but both like iso 80 the best. I do not need a high definition video - so that difference is not important.

Sorry, haven't had the opportunity to try and compare the SX1is to the other two models.I'll tell you this though, after taking the SX30is for a test run there is NO WAY I would keep it over my SX20is when it xomes to the discussion of image quality.

Everyone complains about the "crowded" MPs on a "small" sensor, but can't you just take lower MP pictures and still take advantage of the upgraded features of the SX30IS? That is, you don't have to use ALL 14.1 MPs to take pics. You can scale picture size back in the settings (at least in the older model I have) and get higher "quality" pics (less noise but a smaller picture). I think this is something critics should keep that in mind. A 35X is a great attraction, especially for a sports fanatic like me who takes pics from far away at some events and 720p video is as well.

I think the SX40 may be better than SX30 but there is no RAW output. Maybe time for a T3i!

Does anyone know the differences in the sensor size for the two cameras? Megapixel count doesn't necessarily mean better PQ, but a larger sensor does, right?

Look up "canon chdk". It's a firmware that you load from your sd card. I'm getting optical zoom in my SD800IS, along with many other features, like shooting in raw, and control over shutter speed. For those cameras with aperture control (mine just has a NS filter), you can even adjust that.Still, I really like the looks of the SX1 coming out. I'm going to start saving for Christmas now.

In short, comparing to SX110, at least on paper, SX120 got better processor, but worse sensor and shorter battery life.In other words, I think that at best these models are about the same, at worst SX120 is a step down.About SX200: judging by reviews, it seems that SX110 is (well... was) better in low light. May be that's the reason why Canon dumbed down SX120 so the image quality of different cameras will better agree with their price points.

The G15 is a discontinued and replaced by the G16. I bough the G16 for its small size with robust features to compliment my Canon 5D. The SX260 is much larger than the G16 and didn't fit my needs. As for the G16 performance, spectacular! the large sensor captures large amounts of RAW data for great pictures. On board star trail processing feature has produced some DLSR quality shots. My biggest dilemma is the confusion going from 5D controls to the completely different G16 control. I still give it a 5 star rating!

I have had both versions of the lens and definitely preferred the one with IS. With that said, the difference in price is significant and the non-stabilized version produces superb images. If you are shooting outdoors with plenty of light it is perfect. If light is an issue when shooting I would definitely save up for the IS version.

Thank you! I haven't heard of the sx40 i'll check it out. I really like the specs. On the sx230. The images looked better than the Sony hx9 I was gonna get. But the canon seem to beat it with quality of picture. Thanks again

I recently bought the SX10IS and it's a nice camera, zoom is kind of noisy for the price, so I am sending it back and waiting on the SX1IS to come in. I want the faster burst rate, the HD movie quality and the remote control features.

Well, it's just the size of the sensor troubles me. What kind of picture is this going to take at even a 400 ISO? Nevermind 800 or higher.I just wonder if it's worth getting a camera this big when the sx200IS can be had for almost half the price, it's way easier to carry, and when you add the chdk firmware, will be almost as functional.I suppose if this were to be your only camera, but personally, I'd like to see what they do with the Rebel, either later this year or next. Or if I have a "rich uncle die", buy the 5D Mark II ;-)

The link for the comparison at cameralabs.com is not applicable because it tested the Sigma 18-200 DC prior to the release of the OS version. The OS version is much better optically than its predecessor and also includes HSM (High Speed Motor). I have read test reviews and comparisons at other sites such as popphoto that indicate the Sigma is sharper and has less distortion than the Nikon 18-200 VR, but they also state it is slightly louder. I just received my Sigma 18-200 OS today and have done limited testing, but I can tell you the AF and OS noise are not bad (the OS chirps when it turns on and off). The Sigma AF is louder than my Nikon 18-135 (w/SWM), but quieter than the AF on my Nikon 50mm 1.8 prime (wo/SWM). The HSM AF seems just as fast as my Nikon lenses. The build quality feels better than the Nikon 18-135; the zoom is smooth and solid. The first things I tested today were barrel distortion and OS functionality. Barrel distortion is present at the wide end on ALL wide-range zooms, but the Sigma controls it better. The Sigma has noticeably less barrel distortion at 18mm than my Nikon. This benefit of the Sigma is moot really, because barrel distortion of both lenses can easily be corrected with software. The OS functions very well, I can shoot hand-held down to 1/10th of a second with no blur. I will post again after I have time to do more testing.

Not easy Liz! It irritates me that virtually all the "fit-in-your-pocket" manufacturers have eliminated the optical viewfinder. Knowing this in advance the sx280 has the best features/results of this type of camera in it's price range. See www.cnet.com for a good review of this camera.

To Tom Martin or anyone who can help, excluding video, why is the EOS 50D 15.1MP a higher quality than the T1i or T2i?I'm trying to decide between the three and when I look at the list of specs for them, they all seem almost identical from what I can tell. I'm sure I'm missing something. Does the 50D have a more rugged build?Thanks to anyone who contributes an opinion on this.

You'll be better off with a dSLR in the long run, yes you have to change lenses, and you wont get as long a zoom without spending thousands, but, when you see how small the sensor is on the SX20IS compasred to Rebel you begin to understand why.http://www.cambridgeincolour.com/tutorials/digital-camera-sensor-size.htmThe Rebel sensor is the Red 1.6 APS-C and the SX20IS is the Purple 1/2 (1/2.3").

Why do you say " that the SX10IS will be better for photos" when this is the bottom line of the review you link: Canon's PowerShot SX1 IS has justifiably become one of the most talked-about super-zoom cameras on the market today. It takes the already capable PowerShot SX10 IS with its powerful 20x zoom and articulated screen, but swaps the sensor for a CMOS version which can deliver both HD video recording and fast continuous shooting. As such, the SX1 IS becomes the latest and arguably one of the best hybrid cameras to date, delivering 10 Megapixel stills at up to 4fps with a decent degree of manual control, along with Full HD video in the 1080p format. The SX1 IS is more than just the SX10 IS with HD and fast continuous shooting though. Canon's also fitted an HDMI port to deliver quality output to an HDTV, supplied an infra red remote control to make those HD slideshows even more convenient, and swapped both the viewfinder and screen for wider 16:9 shaped models to better-suit the HD video mode. There's also a digital teleconverter option which can double the reach of the lens without any loss of quality when filming video. The lens motor is also the improved silent mechanism used on higher end cameras and comes with RAW without need to update firmware (my additional comments...the only downside I see is the lower resolution viewfinder but I rarely use viewfinders any more anyway).

I cannot give you a definitive answer. I suspect that the differentiation between the 3000, 3100, and 3200 has been the sensor in terms of megapixels and speed range rather than the actual dimensions. In plain words probably yes. Have you gone onto the Delkin web site and asked?

Well to be very honest I don't feel I could compare something I am not familiar with. I would only be reading reviews about the Finepix S1800 and not actually comparing 2 products. I can only say (since I bought it for my son who is 36) that the pictures he takes with it are amazing and the price was very reasonable. I am sorry but I think if I tried to compare it to something I am not familiar with I would be giving you false information.
