Has anyone tried one of these lenses with a 7D, 550 or Rebel?
Its not really a 2000mm, but actually a 1200mm, which at 1.6 crop looks like 1920mm. And in reality its a telescope with a camera adapter. The price is manageable. Still looks like it would be fun if its decent.
I believe the brand is Visionking. Anyone have any idea of the CA, etc.
