Movie cameras which are capable of taking still shots always have bad quality output.

I will recommend that you get a standalone digital camera for your still shots. For 500 dollars you can get the Sony-DSC H5.

* The 7.2 effective Megapixel Cyber-shot DSC-H5 digital camera
* Two NiMH rechargeable AA batteries
* Battery charger
* Lens cap w/retaining strap
* Lens hood
* Conversion lens adapter
* Wrist strap
* USB cable
* A/V cable
* CD-ROM featuring Sony Cyber-shot Viewer
* Fold-out "Read This FIrst" guide + 120 page camera manual (both printed)
3 inch LCD Display
Full manual controls
