Here's a Nice Vintage Asahi Optical Pentax 50mm f/2 Standard Lens--- in M42 Pentax screwmount for early Pentax cameras like the early K, H or S and possibly Spotmatic.  I'm not sure about that so I'll expect you to know what you are buying and what it can be used on.   It is a late 1950's or early 1960's lens.  It is what is known as the "Preset" aperture---  where you set it at the front of the lens. 

It's in Very Good condition--- Nice Glass with some exterior cosmetic wear.   It has some nicks and marks on the outside barrel, some paint wear to the edges and knurling, but no major dinks or scratches.  The aperture works, but it has a little bit of oil.   The glass is Very Nice---  beautifully clear with No noticeable fog, or balsam separation and just a few almost microscoptic dust specs but it is doubtful it will affect photos.   It's NOT Mint so don't expect it to be--- it's Well Used.  Aside from that--- it's in nice condition, with no other issues.  

US Shipping will be $10.50.   It will be packed well and safe.   International Shipping via the ebay shipping program---- no private or outside of ebay shipping.  Shipped within two business days of purchase.

PLEASE READ THIS--- By Buying this you also Agree with this:  Reality check.... I am not Amazon or a professional Camera Store seller--- just a camera collector/shooter selling a surplus of Used items.  I'm not here trying to rip anybody off or sneak one past you.    But that said... I'm not into having things go back and forth based on "Opinion", or risk part-swapping either.  So it's being sold As Is, No Warranty, No Buyer's Remorse, No Try-outs, No Returns--- no deciding that you don't like it because you shined a flashlight in it, which showed some glare and over-exaggerated a flaw, as every flashlight test will--- it's well-used so it might Not be perfect.   I try to be detailed and truthful but I can't describe every every millimeter of it, so there may be a nick or blemish or a couple specs of dust that I failed to mention... but they would hardly diminish it... unless you expect everything to be 100% Perfect and Like New---- which is unreasonable.  AND.... this is a Vintage, Antique, Used lens that's about 70+ years-old with some minor flaws--- if you can't accept that it's likely Not Perfect, don't buy it.  What you see is what you'll get and I package my items well, so it arrives in the same condition as shown.
