That's pretty much what I had in mind. Somewhat compact with good zoom. I was also looking at one by FujiFilm that was much less expensive and had 18x zoom.http://usa.canon.com/cusa/consumer/products/cameras/digital_cameras/powershot_sx150_is
Never used this model but it looks fairly decent for what you are interested in doing..
I noticed these cameras have 5x optical zoom now. That's good for a camera this size. Not sure if that would fit the bill or not...thinking of trying a cam with more zoom, but also want it to be somewhat compact. I tote enough stuff into the woods while hunting. lolHey dx
I use a Nikon Coolpix that I bought for my wife's bday...moderate zoom in a small package...About the same as a pack of cigarettes...I carry it in my shirt pocket especially in the cold weather to keep the batteries warm and charged.
I had a ultra compact Sony Cybershot 10 mp, with 3x zoom but the auto-focus died. It took decent shots, but now I'm looking for something with more zoom, decent in low light, somewhat compact.
