Sad to say this failure has just happened to me. I'm in Tanzania at the moment and can't deal with the repair until I return to the US but the darn thing just came apart as I was using it. I've had it for about half a year. I did buy it used though...
I am so sorry to hear that! Pentax needs to realize they have an issue with this lens! I am happy to say that mine is being replaced by Pentax though. It has been two months getting to this point though. I am hoping to have it this coming week.

I would strongly suggest, if you go through Precision Camera, that you contact Steve Mongrain. He is Senior Customer Experience Manager. Email is Smongrain@precisioncamera.com. Phone is 860-272-2160. I spent over a month dealing with others and finally got a bit forceful and they connected me with Steve and things went much better.

Also, my lens was out of warranty as well. Please let me know how your experience goes.

You are welcome. Also, my lens was a display model when I bought it so was considered used as well. I wish you luck in getting yours either repaired or replaced!

Wow! This is totally unacceptable for such an expensive lens!

I just mailed my DFA 150 -450 to Precision yesterday (9/25/17) for excactly the same thing. Never dropped and never bumped. i have used it for about 11 months and taking it out of the case it just came apart a the original poster said. Unfortuantly I failed to take any pictures of it only including the discription of the event. I may have to contact this Smongrain@precisioncamera.com before it arrives to state my claim. Any sugestions for me.

my suggestions:

I would pm the other posters who have had this problem and get as much info about their claim as possible

serial numbers

who they have deal with at the repair place

the details of their experiences if there is more to the stories than has been posted.

provide all of that info as part of your claim

I am really getting worried about this now

I wonder how to find out if these lenses could be closely related re: manufacturing date

I also wonder if we could find out if this has happened to more lenses than we know about.

good luck

This email is to alert you to this serious fault with the lens. Pentax is doing something poorly in QC. Please advise as to repair or replacement. Thank you for your attention to this problem.

I am sorry I cannot figure out how to reply to your PM. The serial number of my lens that failed (came apart) was 4403169. Evidently it was deemed unrepairable. Pentax replaced it with a refurbished lens. It took two months to get the issue resolved and receive my replacement.

I too feel there is an obvious design flaw with this lens. I would be most interested in knowing the cause of this problem and if there have been design changes made to correct the problem. I am quite concerned about the possibility of the same thing happening with the one I now have.

My D FA 150-450mm lens # 4405843.

mine is HD Pentax-D FA 150-450 mm F 4.5-5.6 ED DC AW 4372150

not sure how to read the serial numbering system If I had to guess mine is an earlier production.

4403169
4405843



no problem yet but with three reported incidents I wonder if I should be worried.

mine was not bought from a dealer but on the "experienced" market so I doubt if I would get any warranty protection.

anyone has any thoughts about preventative actions

This is the most recent contact with Precision. The Responded with at phone call some 4 or 5 days afer recieving my lens and said they were giving it to the technitions for evaluation.. I have heard nothing since so I sent this most recent email to Steven Mongrain for a response. Hope i hear some thing soon.

Since I haven’t heard from you I thought that I would check back in on my lens and find out what your technicians found and what solution is being taken. It has been several weeks and a determination should be available. Please advise soon as the “birding season” is about to start for me. I need my lens or a new one as it is under warranty. Look to hear from you soon.

i recieved a reply next day from Steven Mongrain at Precision on my lens and the following is his respons: I hope Ricoh / Pentax get it right and send it back soon.


Good Morning Gary,

I sent an a request for an update yesterday to Ricoh and just heard back a few moments ago. Ricoh has advised the lens should proceed as repair to the Ricoh-Pentax factory overseas as a warranty repair. Precision’s evaluation only entailed that there was no customer abuse to lens to cause the barrel separation. The repair required would need to be determined by the Ricoh-Pentax factory for this model, and specific issue of the barrel separation.

I will ensure this ships to the Ricoh-Pentax factory today and request if the repair can be expedited. Typical turnaround time is 3-5 weeks with ship days included, but I will work with Ricoh to get this back to you as quickly as possible in good working order.

If you have any questions or further concerns please let me know.

I mailed my DFA 150-450 lense to Precision on Sept 19,2017 and emailed, Smongrain@precisioncamera expaining that the lens was on its way and the condition.
I finally got back the same lens from Ricoh/Pentax repaired. However I was in the haspital recovering from a heart attack. My daughter in law signed for the lens on Novenber 29, 2017.
It has been a couple of weeks and finally got to use it a little yesterday as we went to a refuge near hear and, with my wife driveing I was able to see that it actualy worked.
Will do more testing as soon as I am able. Other than the long duration without the lens, I am satisfied with Precision's handeling of the situation. Dissapointed with Ricoh/Pentax however.
