G7 vs S3 IS vs S80...... ISO comparison

Just received my G7 today and did some quick tests with the S3 IS and the S80 for comparison.

I'm very impressed with the G7, its built very nice and the new Digic III is fast. Some improvments in the menu system too.

It's very solid feeling and is mainly metal, with only the battery, ports, and top panel made from plastic. Even the top control knobs are metal. Its slightly larger than the S80, but still very compact.

Look way cool for such a small camera. My things have improved over the past few years.

Thanks GNMink, very useful comparison!!

It does a lot for me in several aspects... first, I see that any of this cameras from canon will produce the same result if resized to 800x600, so if web is your final destination, probably more money wouldnt get better pictures.

But, the 100% crops show clearly the increased MegaPixels of the G7, therefore a bigger piece of the image, with less noise (apparently through in-camera noise reduction from the pattern of noise) than that of its rivals. And even though the ISO1600 is very noisy, I believe its comparable to the ISO400 of my fathers Pro1, so you have 2 more f/stops to play with light!

Can you comment about the IS? How is the filling of that? How about the other features? bigger LCD? How is the Optical Viewfinder? How about autofocus in low light? and speed of focus?

Thanks again for the scoup of the G7, you will surely receive tons of questions. Thanks truly,

A very nice comparison of these three cameras. Thank You!

Nice to hear you think it's fast. Would you say noticeably quicker than the S3? Also, how about the LCD? It's described as "wide angle view". Is there a noticeable advantage versus a standard LCD in terms of viewing at angles? I know it's kind of gimmicky, but have you goofed around with the facial recognition focus feature? Any thoughts on battery life yet?

It starts up very fast, and focus is very quick and accurate. Not sure if its faster than the S3, my hunch is that it focus is just a little quicker.

The LCD is very bright and seems to be viewable at all angles. One big surprise is the optical rangefinder, its clearer than I figured it would be and is pretty accurate when zoomed altho its only 80% view but definetly usable in condtions that the LCD is not readable.

The face recognition feature works! works very well indeed. The subject has to be looking towards the camera for it to recongize the face but tracks very well and can recongize several faces (max of 9)

I like the camera alot, it has much to offer. I think G3, G5, and G6 users looking to upgrade will be disapointed in the size and ergonomics (lack of a grip) and will probably miss the tilt/swivel LCD. But Image quality is very good and the camera certainly isn't missing any controls/features and the IS is a big plus.

Obviously the G7 is not really a continuation of the G series, its a whole new design as an advanced compact. I think its the best compact camera out right now. I've heard alot of talk about the ISO 1600 performace but atleast it has the ability to "get" the shot and IMO ISO 1600 is as good as it gets right now with such a small sensor (Fuji F30 excluded! LOL)

Obviously Canon has decided that the 400D is priced agressively enough now that it would appeal to G series users looking for something new.
The S3 IS has everything you could want and is priced $200 less than the G7 so its a tough call between the two.

I'm gonna wait and see what the G7 reviews look like, but this is a huge help, and thanks for posting the samples. Based on what I see in the samples I'm deffinitely still considering the G7.

With the smaller grip, does it feel secure holding it with one hand (something I often do between shots with the G3).

I'd used the supplied neck strap! LOL

Thanks. That's what I figured. It looks pretty small (both the overall and the grip). Overall smallness will be a plus to me. The easier it is to take it places the better.

Thanks for the comparison. Wonder what the 400 and 800 shots would look like after a pass through NeatImage?

Thanks for the comparative tests. Having the S3 IS, I was surprised it held up as well as it did at ISO 400 .. not up to the G7, but not *far* worse. With an SD700IS, great for "go anywhere", and the S3 IS (plus a 20D and lenses if I want to lug stuff), I will likely pass on the G7. It definitely has better IQ than the S3, but there is no niche between the SD700 and S3 where it can fit.

Thanks for the comparison. . .
It helps me . . .but in the end, which one is the best catch?
