actually, the first reviews of the sigma have been kind of disappointing
dpreview
it has potential, but it isn't the holy grail yet.
the holy grail is years away for any digital format right now...even hdtv..
even the best cameras have problems if the scenes aren't lit right...dpreview isn't even sure if it;s a sensor issue or a photo pro issue.
Conclusion - Pros
The best resolution per output pixel we've ever seen, X3 lives up to the hype
The first digital camera to offer true single pixel resolution, goes beyond Nyquist frequency
Resolution of enlarged images virtually indistinguishable from six megapixel Bayer D-SLR
Relatively good tonal balance although default curve can be a little contrasty
Color accurate if a little under-saturated, especially foliage greens
Good automatic white balance, pre-programmed WB settings work well
Nice channel split histogram, can magnify in histogram mode
Undelete feature (recover last image deleted)
Fast operation, good startup / operation time, slightly slow CF write performance
Auto focus relatively fast, worked well even in lower light levels
Sigma Photo Pro RAW conversion software is superb, lots of adjustment and all in real-time
Firewire (IEEE 1394) and USB connectivity
Well designed LCD cover (allows access to delete button)
Easy to understand control layout
Dust protector
IBM Microdrive compatible
Once familiar the sports finder is useful, especially horizontal / vertical alignment
Conclusion - Cons
No in-camera JPEG, storage implications of shooting RAW
Color clipping / gray halos - not clear if a sensor or Photo Pro issue
Unnatural blue skies / chromatic aberration sensitivity - linked problems? *
Disappointing long exposure performance
Limited sensitivity, some softness at higher ISO, noise higher in red hues
Long exposures limited to one second at ISO 200 and 400
Half-stop exposure compensation / adjustment can feel limiting
Awkward power solution (two different sets of batteries)
Heavier and bulkier than some of the competition (although never feels too big)
Sigma QC should ensure no dust on sensor from factory
Continuous shooting rate limited to 2 frames per second at Hi resolution
No onboard PC Sync flash socket (req. optional adapter)
Photo Pro JPEG output quality issue
First of a kind
