I know mirror lens quality is no where near as good as a "proper" lens
but, I am looking for one, to play with and they fit the budget nicely (im saving up for a D90)
the two that seem to be the best of the bunch are the
sigma 600 mm and the tamron sp 500mm
both are fixed F8
has any body had any experience of ether of these, and which woudl you recomend.
I have seeen soem 1000mm opteca ones but they dont look as good quality build or function wise.
any advice woudl be great.
