Question
Hello,
I received a number of old lenses from a friend of mine and am thinking about selling them on Ebay. However I have absolutely no clue how much they are worth (if anything at all)and I dont want to get ripped of so I was wondering if you could give me your opinion on how much they would be worth.

#1
SMC PENTAX-M 3.5/28
SMC PENTAX-M 1:3.5, 28mm, and the number on it is 6389992

#2
SMC PENTAX-M 3.5/135
SMC PENTAX-M 1:3.5, 135mm, and the number on it is 6379949

#3
SMC PENTAX-M 1:2, 50mm, and the number is 4835615

#4
SMC Pentax-M 1:2 50mm, and the number is 4976621
5430779

Thank you for your time.  

Answer
Hi Megan,

Unfortunately used camera camera gear doesn't have the value it used to.  Fortunately, your lenses will work on Pentax digital cameras so you should be able to sell them.  

28mm f/3.5 is worth about $20 dollars.
135mm f/3.5 also about $20 dollars.
50mm f/2.0 about $40 (for  both of them)
