Excellent eyepiece

This is a well matched eyepiece for the Pentax 80MM spotting scope. Eye relief makes it easy to use with glasses but the relief is better without glasses.

Disappointing

I bought this zoom lens for a Pentax PF-80ED-A 80mm Spotting Scope, expecting the image to be sharp all the way up to 63x. While it is clear and sharp at low power it is certainly not at full power. I don't think there is anything wrong with it. I think my expectations were probably too high.

Is this eyepiece threaded at 42mm on the top to attach cameras like the XW eyepieces are?

Some reviewers say, if you get this eyepiece with PF-65EDA, it doesn't fit into the provided case for the scope. Is that right?
Asked by: Cuneyt
The case included with the Pentax PF-65EDAII 65mm Spotting Scope was designed to be used with the open back or fully closed depending on the size of the eyepiece attach to the scope. You would not be able to fully closed the bag when attaching Pentax SMC 8-24mm Zoom Eyepiece. The lenght of the case on the outer curve is 16.5''. The case has 2 zippers, 1 will give you access to the tripod mount. The second one will allow access to mount your eyepiece.
