As i mentioned before, i use the F828 as my "carry along camera". i.e. Since i like to have a camera within arms reach, the 1Ds with its big footprint etc is not quite friendly in that matter. A lot of the times, photo ops present themselves when one is least expecting it. The F828 has worked for me in those experiences, quite well. My previous photos are evidence. I use it as my back up camera on a daily basis. I can throw it into my flight bag or backpack and forget it is there.
Regards to the Chromatic abberation, i have encountered it on perhaps 1% of my shots and it has been lighting (of certain type) has been coming from a certain angle. This manifest itself on the sharp edges and can be easily cleared out in photoshop. It doesnt infect the camera throughout its range.
the following picture is further evidence of use when conditions are not optimum,taken in very low light-at dusk-with motion.
This camera has worked for me and i am happy with it. Good luck with your choice.
