A700 with limited in-camera editing (new feature?)

Thanks, These were very helpful. Luckily they were about what I had hoped. Actually, I was hoping for a little cleaner ISO 400, but, for the price and size, I can't beat it. (I have a Nikon D70 SLR which has a clean ISO 400 so I am spoiled) It looks like the S2 is the noisiest of all of them. I can't really tell the difference between the 610 and the 700. By the way, I just ordered mine off of B&H (the A700). They have it for $319. I bought a 1 Gig card from buy.com. After rebate it's $25. A Kingston. Can't wait to get the camera. I wanted a Fuji V10, but after looking at the output, even the ISO 200 pictures had a water color effect to them. Very highly processed, ISO 1600 was unusable. I think ISO 800 on the A700 is very usable in a pinch.

Thanks Again, I really appreciate it.

I was looking at the EXIF information from the pictures and I can't see where the ISO is for the A700, it just says normal. All the others say the actual ISO, but the pictures from the A700 say normal.

I just looked at a number of pictures taken with the A700 and none contain the ISO value in the EXIF file.

I've just looked at the photos Bob C. posted and am kinda confused about the sensitivity on canon cameras. It seems to me that each canon camera has different sensitivity. Here is what I found after looking at the exif data of all the photos.

A700:
ISO400: f7.1, 1/1250s
ISO800: f8.0, 1/1600s

A610:
ISO400: f8.0, 1/1600s

S2:
ISO400: f8.0, 1/1000s

As you can see, A610 at ISO400 gives the same sensitivity as ISO800 on A700(same aperture value and shutter speed). So we can't just compare the image quality of these 2 cameras at the same ISO, right? So to be fair, we have to compare ISO400 on A610 to ISO800 on A700, right?

And since the image quality at ISO400 on A610 is much better(noisewise) than ISO800 on A700, can we conclude that the old 5mp 1.8" CCD(on A610) is superior to the new 6mp 2.5" CCD?

On the other hand it seems that the new 6mp CCD seems to do a much better job that the old 5mp 2.5" CCD on S2, judging from the aperture values and shutter speeds. Would this mean that S3 will have better image quality than S2?

Do i understand it right? I hope maybe you guys can explain this to me. Thank you very much.

Here is the complete comparison:

A700:
ISO80: f4, 1/640s
ISO100: f4, 1/800s
ISO200: f4.5, 1/1250s
ISO400: f7.1, 1/1250s
ISO800: f8.0, 1/1600s

A610:
ISO50: f4, 1/640s
ISO100: f4.5, 1/1250s
ISO200: f/6.3, 1/1250s
ISO400: f8.0, 1/1600s

S2:
ISO50: f4, 1/500s
ISO100: f/4, 1/1000s
ISO200: f/5.6, 1/1000s
ISO400: f8.0, 1/1000s

Assuming that all these settings gave the same exposure of the same scene with constant lighting, I would say Canon is playing ISO games with us consumers. What other explanation is there?

Given that this was an outdoor picture I am not sure we can jump to the conclusion that Canon is playing with the ISO values (although it may turn out to be correct). Light can easily change by 1 f-stop outside within a few seconds (with wind blown clouds). These are just another useful data point until we can get a formal review, or pictures under a more uniform set of conditions.

Perhaps Bob C., who took the pictures, can shed some light on the situation. How close in time were the pictures taken and what were his observations of the light variations? Were there broken clouds in the sky near the sun that could drastically change the lighting during the time of the experiment?

That would be helpful information.

All the photos were take within about 5 minutes on a sunny day in California. Thus, I would say that they were taken under almost exactly the same conditions.

It is interesting to note that the ISO number for the A700 is displayed when reviewing the picture while still in the camera, but it is not included in the EXIF file.

Thanks, Bob. Your information is quite enlightening.

"? How could you call the A700 the "Flagship" of the A-series if the A620 is better?."

well, if canon insists the a700 is the flagship of a-series, that's a bad sign that canon is waving the white flag of defeat to sony and other manufacturers.

Hopefully, in a few days I will be able to test the camera under more uniform conditions (indoors). I ordered one from B&H and I have an older Canon PowerShot 230 that I can compare it to. Until then, I would be interested in seeing what other people are getting.
