I have just purchased a canon 20d dslr.
I have been looking at the lens prices on fleabay for a 300mm zoom/telephoto lens and find at the moment they are out of my price range.
I have noticed though that some lens for other makes of camera are within my price range and that adaptors are available to make them fit on to my camera.
I know I would have to use it in manual mode for focusing.
My question is. is it practical to do this if so what makes of lens should I look out for and which should I avoid.
Would this cause any problems using the camera.
I have also noticed even though the camera is supposed to be able to use all EF and EFS lens some sellers say not suitable for digitial cameras on their listings for EF lenses.
Why is this?
Hope someone can advise me.
