I purchased a Tamron 28-75 and the blades are sticking. It is no longer under warranty. Tamron wants at least 140 plus shipping to fix the lens. I have no idea if that's fair or if its over the top. My question is should I coin up and spend $140 dollars to make sure it is done correctly from the factory or are there cheaper and reputable alternatives to this solution?
I have no idea how difficult it is to correct the issue nor if it requires the professional level of Tamron.
Thanks

might be better to just take the hit. You can still keep the resale on the lens where as getting it taken to a 3rd party, you be taking a risk with the electronics and what not.

Would eric do it? Or does he only work on Pentax glass?

Yup but I've only sent him like manual lenses but haven't tried AF ones. I think it can't hurt to ask him.

Sorry to hear that this is in fact the problem. I Hoped, I was wrong. It definitely requires someone qualified to do the job. It certainly can't hurt to ask the resident guy, Eric. However, Tamron service will have the parts, jigs, tools, etc to do the repair. There are a number of reasons the aperture could be sticking, dirt and oil being only one of them.
