Yes, it is clear enough for bird watching. 

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. 

This screen is a sheet- made of fabric. It has built in holes on the top and sides to secure to something... my plan is to use hanging plant hooks under my deck and hang in on the patio space. A clothesline would work but if windy might need to secure the sides or bottom too... 

I did not see anything in the spec. sheet for this camera about mounting it on a tripod but if the hole is 1/4" you can attach it to this tripod but if it has the larger hole you would have to get an adapter. According to the 2018 spec. sheet, this camera weight is 3.10 lbs. so this tripod should work. I hope this helps. 

You can focus clear about 6 ft as far as I know
