Well I've ordered my Ixus 85IS (SD 770) now. After reading all I could find online, countless reviews, I decided that even without the CHDK this was still one of the best and smallest digital cameras out there, as my main criteria was for it to be pocket sized.
I've gotta say it was a close call, as there were a few similar models, including the Nikon Coolpix s600, Olympus Mju 1020, but despite it's apparent downfalls with noise above ISO400, it comes out better in all other areas - and it sure beats my old fixed focus Fujifilm A605.
Now if someone could crack the DryOS on this model and get the CHDK working on it that would be great.
It seems like someone has already managed to extract the firmware from this model, which seems to be a crucial step, but if you need any help or testing with this specific model let me know.
I know I won't be able to adapt the CHDK myself as I'm not that experienced with programming, but if anyone wants to test a CHDK build on the Ixus 85IS(SD770) just let me know and I'd be willing to help out.
Cheers,
ROGUE
