[EX Q]: I got this camera from costco almost immediately after my old olympus digital camera bit the dust. Unfortunately, mine was returned within three days. I had no issues shooting photos, but when playing video on it (at 1920x1080i) it is not worth it. First thing to go wrong with any compact dSLR is image stabilization, and in its defense, I did get a few very blurry.
[EX A]:
Bad review
