S100 vs. X10 High ISO Comparison

I compared the X10 to the S100, to see how they handle low-light situations.
To my surprise (somewhat like with the G12) the S100 produced darker images
with the exact same exposure settings as the X10. Can anyone say why?

The comparison can be seen on my blog.

Thanks,

different cameras with different lenses with different sensors (size and type) with different analog to digital converters with different imaging processors. If you shot in jpg, then different image processing methods too. even shot in raw, photos do not look the same with similar settings. so there are many factors affecting the outcome of the image. even with the same sensor, images will look different.

Thanks,
I expect differences in image quality, colors, sharpness, etc.
but a 2/3 stop exposure difference using the same settings?

what is a proper exposure?

I think that overall, the colors of the toys looks better on the S100 with it's default exposure settings than with your adjusted exposure settings. It's most apparent on the giraffe, the wolf, and the tiger coin... I will give you that with the default exposures, the X10 appears to have better detail in certain parts, and the S100, better details in other parts. I would guess that this is caused by the focus selection more than anything. Noise: There seems to be more noise in the X10, so, does that make it a winner?
Looking at what I consider the best of the pics- the details in the man's shirt is better on the S100- but on the wolf, it appears less sharp- where as the X10 is the opposite - the wolf is better, and the man worse. The noise is certainly worse on the X10.. Wonder if processing RAW images would result in better output. In any case, I'd give the win to the S100...

Better lighting might improve the noise aspect-

I really wanted to make a spoof post that had S100 image on the left, X10 image on the right, otherwise identical, but fill the x10 image with a bunch of white circles. :P

eyalg, i might have found your answer on exposure. to make things easier for the user by having round numbers for ISO settings such as ISO 100, 200 etc, camera makers round their ISO settings. Up to 20% is allowed by the International Standards Organization. Hence, even if you set both cameras to the same ISO, its plausible that one camera would be really 20% under while the other be 20% over.

Thanks for the information.
It makes sense that the ISO settings are not accurate,
and in this case, a 2/3 stop difference, which is quite significant.

I played with an X10 this weekend...and since it has a non-interchangeable lens...I'm not a fan. I mean it's cool and retro, but it doesn't really offer more than the S100 in a much bigger/bulkier/heavier body...also, if I remember correctly it starts at 28mm vs. 24mm, which for me is a big selling point on the S100. And no ND filter..and...well, I could go on

I would have to completely agree with you on this point..
