I guess i would wait until i'll have enough money to buy me some zoom lens with f2/8.
Thanks very much for all the info.
Hmmm, didn't take much to convince you of the futility of this setup, but I like trying futile things.
Just some quick shots made after reading this thread: These were shot with a K20D + KatzEye split prism finder, Tamron 70-300 @300mm, manually focused. A Tokina EL 2X TC I bought recently to convert it into a PK/A extension tube (probably about the same optical quality as the Vivitar you were looking at), mounted on a monopod. Nothing to write home about but I think still acceptable. The short focus throw makes focusing a chore but doable. I go by the adage; it's better to get something rather than nothing. I suppose one would double the aperture value in the exif to arrive at the true aperture value.
Thanks,
