What is the differeence of a Vivitar RL Edition Lens?

I recently purchase a 24mm f2 Vivitar RL Edition lens and can't find

anything about on the web. I also have a regular vivitar 24mm f2

and find the two virtually identical except the RL Edition label and

I like to know if anybody out there know if there is any optical

diffence between the regular and RL edition lens and is the RL

edition a higher grade lens then the regular, better coating perhaps?

 

Your imput is appreciated, thanks.

The RL was the same lens as the non RL it just had more marketing hype and a better warrenty. NO optical advantage NO biuld quality advantage. Just hype.

The Vivitar RL Edition lenses are identical to the non RL lenses. The only difference is that they came with a seven year warranty, as opposed to Vivitar's usual five year warranty. They came from the same assembly line. It was a marketing gimmick.
