Hello,

As promised;

If the lens is past B&H’s return period it should be sent into our shop (which is C.R.I.S.) along with a copy of the sales receipt, and a note with the customer’s name, address, phone and a description of the problem.

The address for our shop is:

PENTAX Service Department
250 North 54th Street
Chandler, AZ 85226

877 269-7179

Hey Chuck, thanks very much for asking them for me...I usually get no response from them

Just wondering, would I have to send it to the american repair center (CRIS) or could I use the Canadian one? I live in Canada, is why I'm asking.

I feel your disappointment and if you were in my area, I might fix it for you. Since you are past the exchange period, perhaps just send it to Pentax service centre and hope for the best. Limited lenses are well designed and well made, but sadly Pentax assembling QC is just not as tight as I hope for.

This is how mine looks after rearranging the blades myself. One blade is still closes a little more than it should be but much better than b4.

Well, how's this for a shot in the dark. Do you live anywhere near Vancouver, BC?

That looks pretty sweet, your post-repair aperture

As a matter of fact, I am. I can give it a shot as your last resort.

I'm going to try to give pentax canada a call to see if they can do anything for me (I'd rather not ship all the way to the states if that can be at all avoided...All the way down to Texas no less

), if not, I just might have to take you up on that...the last time I called Pentax Canada, well actually it doesn't really count if they never picked up huh

Thanks heaps for sharing!

A warning to anyone attempting this without prior experience: It is a challenge not to introduce lots of dust into the lens. Also, handling the aperture blades requires care so that they won't stick after the procedure. I'm not saying that the fix is beyond a DIY effort by mere mortals, but it is not as easy as taking a screwdriver and five minutes of free time.
