I started bidding without doing the homework first, i.e. checking these lens before. I wanted something wider than the 50mm super takumar I have and I read the vivitar 28 f/2.5 is a supposedly good lens. I'm bidding for it (now at $26) but have a higher max bid

The seller has 99.6% positive feedback, so I hope the lens are clean, and it's just some sort of dust from the outside the that's showing on the lens

It's an OK lens, certainly not the worst. I had both the 28/2.5 and 135/2.8 Vivitars and they both are sharp. The bokeh doesn't match their Pentax equivalents.
Part of the problem with the 28mm lenses (all of them, not just the Vivitar) is that 28mm once was 'wide' whereas now it is more 'wide-normal' - and hence the role of the lens has changed. The old 28s were designed to be sharp, light and relatively well-corrected at f/8-f/11. Today they're taking roles that see them at f/5.6, f/4, or even wide open, and they're not all equally equipped to do the job. It's not that they're bad lenses, just that they're being used outside of their design. It would be like complaining that your 100mm lens with 3x teleconverter is softer than a 300mm lens.
