what rubbish is the promoter telling u? :thumbsd:
both uses the 1/2.5 inch CCD...
and the TS photos are misleading, some of his excellent nightshoots are 1.3sec exposure, at ISO80.. and most of the good night shoots are taken at ISO80 with long exposure time...
i posted my A570IS photos before.. go search for it.. those were ALL TAKEN USING HANDS ONLI.. no tripod...
period...

nice night shots, but all these photos were taken with long exposure at ISO80.. obviously a tripod was used, some exposure were even 3-4s long.. my A570IS photos can take similar photos too... :lovegrin:

at iso400 and above, the noise level for a series is like sh!t.. haha.. verified by my powershot A570IS, where the CCD is the same 1/2.5 inch Canon CCD, with Digic III processor..
crap.. i using F20 for low light photography...

hello TS, can u post some high ISO photos? like what i did for my A570IS? like say ISO400, ISO800.... that would allow people to make a better informed decision...
i'm holding it with my hands for most of my shots... I have a stable hand. Only a few is with tripod or place on a stable surface.
sorry... i mean anything wrong with me posting good shots with ISO 80 and long exposure time? I might be wrong with the sensor size but so far, all those pics i've seen from A570 IS is disappointing for me.
whoa theory87 everyday got new photos up gd job
the bugis street pic looks a little bit too dark IMO
Not any more for the time being. Not i'm angry or what. I'm entering OCS tomorrow so there is no time

Canon PowerShot A570 IS Reviews
CNET has a review of the Canon PowerShot A570 IS and writes, "Image quality was impressive, especially at lower ISOs, though we noticed some slight artifacts even at the camera's lowest sensitivity of ISO 80, which seemed to become exacerbated by the noise caused by higher ISOs. Still, colors looked accurate, there was plenty of shadow detail, and our images turned out very sharp. ... Overall, the PowerShot A570 IS is a solid compact camera that offers a lot of value for your money. We were a bit disappointed with its high ISO noise, but you'll be hard pressed to find a compact camera at a price like this that has manual exposure controls, optical image stabilization, flash output control, and speedy performance. Plus, similar to all the A-series cameras, this one runs on AA batteries, so if you run out of power, you don't need to wait for charging."
GoodGearGuide has a review of the Canon PowerShot A570IS and writes, "Traditionally, Canon cameras have been renowned for their image quality and in this regard the A570IS certainly impressed. When we opened up our preliminary test shots we were greeted by clean, smooth edges and great detail. The pictures were consistently sharp and crisp, showing that not only is the sensor excellent, but the image stabilisation technology works very well. Normally our outdoors tests return several blurry shots in amongst the clearer pictures, but we encountered none when using the A570IS. For those who find hand shake a problem, the image stabilisation (IS) on this model is an ideal solution."
Steve's Digicams has a review of the Canon PowerShot A570 IS and writes, "Image quality was excellent for a 7-megapixel consumer model. The default quality setting is Large Fine, and we did capture many of our regular sample photos in this mode. The rest were taken using Larger SuperFine, which is what we normally use. That said, the majority of our outdoor samples looked great, showing nice exposures, with beautiful sky detail, and pleasing color balance. Just as we saw with the A560, image noise was average when using ISO 80 - 200. ... like it's brother (A560), I was very happy with the Canon PowerShot A570 IS. With 7-megapixels of resolution, a 4x image stabilized optical zoom lens, 2.5-inch LCD, great movie mode, awesome image quality, and loads of useful exposure modes, the A570 is sure to be a very popular model for 2007. At US$279 or less (4/2007), it's only about $50 more than the A560, which we feel is well worth the added versatility of this new model. That said, the A570 will make an excellent choice for anyone who wants a capable, yet compact and affordable 7-meagpixel digicam."
Let's Go Digital has a review of the Canon PowerShot A570 IS and writes, "The image quality of the Canon PowerShot A570 IS camera is great. The colours are saturated and appear natural. The saturation is a bit strong for my taste, but that is a personal preference. ... Let it be clear: the Canon PowerShot A570 IS satisfied me all around. The compact format invites you to carry it with you at all times. The light weight combined with the optical image stabilizer ensures great user-friendliness, and add image quality to the mix and the Canon PowerShot A570 IS is a great camera."
DCResource has a review of the Canon PowerShot A570 IS and writes, "While it won't break any records, the A570 is a good performer overall. It starts up in 1.4 seconds, focuses quickly (even in low light), and shutter lag isn't an issue. Shot-to-shot delays are minimal. Like all recent Canon cameras, the A570's continuous shooting mode lets you keep shooting -- at 1.6 frames/second in this case -- until your high speed memory card fills up. Battery life was above average. Photo quality was very good. The A570 took well-exposed photos with pleasing color and sharpness, low noise through ISO 400 (in good light), and minimal purple fringing. While redeye continues to be a big problem, there's now a tool in playback mode that quickly removes this annoyance. Too bad you have to run it each time you want to remove redeye!"
Imaging Resource has a review of the Canon PowerShot A570 IS and writes, "The Canon A570 IS is a capable all-around camera with some high-end features that are more useful than exotic. High ISO is usable and image stabilization so useful you almost always want it enabled. Digital zoom was a bit of a disappointment on this 7.1-megapixel camera, but otherwise the DIGIC III image processor provided above average performance yielding some wonderfully natural shots in a variety of settings."
Trusted Reviews has a review of the Canon PowerShot A570 IS and writes, "In terms of image quality, the A570 has many good points and one or two not so good. Exposure and colour rendition are first class as one might expect, and dynamic range is surprisingly good for a 1/2.5-in sensor. The overall level of detail is good, but the lens does produce noticeable spherical distortion at the wide end of the zoom range, and corner sharpness is surprisingly poor. Refreshingly there is no sign of purple fringing even on the brightest highlights. Image noise is very low at up to 200 ISO, reasonable at 400, but becomes a real problem at 800. The 1600 ISO maximum sensitivity, which is touted as a feature of this model, is pretty much useless. However as long as you bear this limitation in mind the PowerShot A570 IS is capable of turning in good results under varied lighting conditions, and will seldom disappoint."
Digital Camera Info has a review of the Canon PowerShot A570IS and writes, "Sadly, more than a few PowerShot A570ISs will likely end up damaged or broken. However, for just over $200, the PowerShot A570IS is a bargain for casual users, who will benefit from its hefty feature set. The face detection and image stabilization combination will save, conservatively, gazillions of snapshots taken by the careless, clueless or chemically-compromised user. It's less likely that the A570IS's other advances a 7.1-megapixel sensor and a high-end ISO of 1600 will help users as much, though their inclusion, coupled with the camera's manual controls and exceptional color performance, make the A570IS an unusual bargain at its price."
Digital Camera Review has a review of the Canon Powershot A570 IS and writes, "With great image and color quality, image stabilization, excellent shutter lag and continuous shooting capability, manual controls and versatile auto performance, this camera can ably serve a novice who never leaves the auto setting or provide a learning tool for someone looking to get some manual experience before possibly jumping into the DSLR world. The optional teleconverter gives the camera a 245mm focal length to bring those distant subjects a bit closer. Overall, anyone who wants good performance at a very reasonable price should give serious consideration to the A570 IS."

seems like A720IS is equally bad too.. i have played with S5IS, and the noise and image quality is also a problem.. i dun need the extra 2x zoom.. so A570IS will still be with me...
anyway, canon compacts A series are not known for superb image quality at high ISOs.... anyway, i am just a noobie photographer...
for sure, an compact camera will never beat DSLR. But aren't photography getting the best out of what you have? you simply need to love and understand your device to do it. And i think A series camera is value for money for that reason
