Vivitar 70-210 f4.5 Made by Kobori

I have this lens who is in good shape that I try to sell it. I bought it with other lenses that that I want
This one from Vivitar is not showing up it the database. Its a PK mount manual lenses.
Strangly, it's will not lock on the mount of my K-5 but mount well on the k1000 and others teleconverter. Any body could have any idea what wrong ?

The lens won't lock because of the extra long shield for the aperture lever (the black bit on the rear of the lens). If you remove the 2 screws holding this on, then you can use a dremel tool or a file to make the shield shorter (about 5mm is enough) and then it will fit fine. Remember to tidy up and short bits of metal after filing it and put some black paint on the shiny metal to remove a source of reflections. And definitely remove the shield before working on it or you could damage the lens with your tools or the metal filings produced when cutting it down!

You are correct , I see the difference with the other lenses.
I use my Dremel like you said, cut in cleany and it work. Need to smooth the corner and paint. I strip a screw. Will see what I can do to replace it

Thank you are an expert +1
