You would not believe how good the image looks. I have been looking around my house and at the moon testing this little guy. I can't see any degradation in the image at all. You will loose a little light. That is expected. I have to use the tele conversion button on this canera to get it to focus. I can set this camera to have a telephoto lens or a wide angle lens attached to the frount. But it will focus real good. My next test will be to record the image and see it on the big screen. I will put the test on youtube when I get the chance.
