M 28/2.8 (version 1)
General Description
In 2007 a gold version of this lens was sold on eBay and it looked so professionally done, that at first I assumed that the lens was factory-made. But Pentax has traditionally only made gold versions of its absolute high-end products (which in this case would have been the M28/2), so now I think that the gold version was not made by Pentax.
