Evening all. Anyone remember the Vivitar 24-48 3.8 S1? Or perhaps, the Vivitar 135 2.8 S1? Trying to find a review/test of the above, not having much luck so I thought I'd ask you oracle's out there for a little help. Point me in the direction of a review if you can, or, speak your piece if you have, owned, used, even abused one. Your own personal thoughts on the above are most welcome. All the best. B.
