Casio EX-H10 vs Fujifilm Finepix F200EXR vs Panasonic Lumix DMC-LX3: Comparison of Full-Resolution Images – Google’s German to English translation is here, and you might like to peruse a related forum discussion on DPReview.
Another newer thread with comparison photos is here (Google’s English translation). technic has a translation:
In good sunny conditions or studio lighting, the images look great. However, in normal use noise processing is a serious problem, even sometimes at 100 ISO. Detail/texture in shadows is removed, more so at higher ISO and from ISO400 it is often unusable for serious photographers (the kind who see this camera as possible alternative for LX3 etc.). He would sometimes prefer the LX3 400 ISO image to 64 ISO image from the H10! Also detail and tone curve are processed more strongly than in other cameras.
Zoom reach up to 10x tele is very nice, but because higher ISO cannot be used for high quality images, the tele setting requires perfect lighting conditions.
I’m suddenly no longer interested in the H10 ;( Of course, this outcome is not surprising considering the very small sensor. For those who print small or have less demanding use, the H10 could still be a great allround camera.
