I already own a DSLR (Canon XTi) and the Canon PowerShot S60. I'm looking to phase the S60 out in favor of an ultra-compact camera that I can take with me to events, concerts, etc. I'm looking for a camera that is good in low-light situations, has image stabilization, is tiny, has decent video recording quality, and a short lag time between shots, and good battery life (or recharging system). Both the Nikon Coolpix S52 and its competitor the Canon PowerShot SD750/790/etc. seem to fit the bill but I was hoping to hear from you guys on what your experiences have been. I'm not attached to the Canon or Nikon brands either so I'd love to hear your recs. Thank you!
