I have the 650-1300mm lens that looks just like that. I got it (knowing it would be poor quality) just to mess around with, and for $200 on ebay. My friend took it to SFO
and had some impressive shots with it. They won't get accepted here for sharpness, but some of them were very good. The build quality of the lens is bad-it is just a tube sliding over another tube to zoom, and there is no aperture adjustment or lens contacts (probably constant f8). But, I still think it is fun to use sometimes.
