Digital zoom 

If you use EN EL 15, you can use these batteries. But I'm not sure if your camera allows them to charge in camera 

Thank you for your question. This model no touch screen, but it can be easily operated by the buttons on the panel. 

this solar camera have 4X digital zoom. 

Step 1: Being careful not to touch the lens, cover the right objective lens (or close your right eye) and turn the central focusing dial until the image seen by the left eye is clear. Step 2: Cover the left lens (or close the left eye) and this time instead of turning the central focusing wheel, turn the diopter adjustment ring (located near the right eyepiece and displayed on the small image in the upper right) until the image is clear. Step 3: Finally look through the binoculars with both eyes until the image is clear and sharp.
