Originally posted by THoog The seller relisted the lens with a corrected set of pictures, clearly showing that the lens WAS the K-mount version, and it's already sold. They even reshot the "with box" photo. Given their 100% feedback rating and the effort they appear to be making to photograph every item they list, I really think they just made an honest mistake and mixed up the image files from the two 14/2.8 listings.
BTW, I did a quick eBay search for "(Samyang,Rokinon,Bower) Pentax", and 95+% of the listings (including Adorama) use stock images with the wrong mount type. Some are clearly marked 'EOS', 'CA', or 'NI' instead of 'KR', but Samyang stopped marking their later lenses this way. This is why some folks insist that Samyang makes both K- and KA- versions of lenses (they don't - if the aperture ring doesn't have an 'A' setting, it's not the K-mount version).
I confess. I wrote a low key message to the seller saying I was absolutely certain that picture #3 was not a K-mount and giving specific reasons why.
Within a few minutes I received a very polite response saying that they would fix the listing.
