Before I read my manual...(

) does anyone know why my relatively "new"
Pentax k200d seems to be draining all the new batteries that I literally replace just after a single days use (maybe 50 shots taken at the most)?
I've been using 4 - Duracell AA (1.5 volts) and if I leave them inside the camera after I've finished using my camera (& it IS in the "off" position

)...I'll have 4 dead batteries the very next time I attempt to use it again.
Off to dig out my manual...but, if anyone has some bright ideas or suggestions...before I return, I'll be all ears!
Thank you in advance!
