Perhaps I should not have been … but I was surprised by the things I had not thought of before buying this lens extender. The first is that it made my autofocus shock reduction camera into basically a manual camera. Perhaps I had not attached the tele-extender properly to my camera, (several times under different conditions). But I could not get the autofocus to work. There’s also another consideration: when you increase the telephoto power, you reduce the area of the objects you are imaging. You are also increasing the speed of the subject in relationship to the frame. When I took a picture of a goose in the back yard, the goose ended up walking partially out of the frame by the end of the extended exposure. When I took a (tripoded) picture of Jupiter, the planet had moved away from the focus point – blurring the image and giving it an extended oval shape. Although I was able to distinguish the moons of Jupiter, four that night, they too were blurred. In both cases the tele-extender worked correctly – as far as I could tell. And in itself it gave clear images. However, I may have been able to gain a better final image by cropping and editing an original from the standard telephoto lens. I haven’t abandoned the tele-extender. I’m experimenting with it to find the appropriate application.
