Reading through the posts looks like im not the only one that had or is having issues with there pentax 150 450mm lens , mine just recently stared to jam when retracing the lens barrel , it would stick around 200mm with a little jiggling i could get it to close fully , the lock also had stopped working , last time i had it out , it would not focus , the motor was running , i disconnected the lens and it appeared the rear optics had falling inside the lens casing , it would only sit in place when the lens was fully retracted , it was not jamming now but rattling , this lens is now 3 years old , I travel ( hike ) with this lens with a heavy strap . im thinking this is the reason it started to jam in the first place , with no warranty remaining , i removed the back lens plate for was curious what had broken inside ,from all the rattling . two round plastic cylinder type , with a screw in the middle fell out , im assuming this is what was holding the rear optics in place , how this came apart i can only guess from me trying to fully close the lens on several occasions , with last time being a struggle , when i tried to focus next time camera was powered up the focus motor strain must have snapped these tabs holding the rear optics in place , and from me trying to fully close it must have weakened the plastic tabs , only explanation i can come up with , I still don't know why then lens was jamming , I have dropped this off to my camera shop for return to supplier , but with no warranty i do not expect anything , only me being out the $3000.00 bucks , anymore then 500 bucks to repair i don't think is worth the risk , i think the parts to repair will be the problem , so my question is from reading all the posts on the issues with this lens , has it been corrected from the manufacture ? and if so is there any production date of the correction . i would hate to purchase another lens keeping the old one for parts , and finding out i have the same Friday production line ..... needless to say i'm very disappointed , being that i had saved and sold a few of my belongings off in order to buy this lens for wildlife photography , but anything with moving parts is always a gamble , wish there were more options with prime long lenes but they just dont exist in the pentax mount , nothing new at least . However one would think you would get more than 3 years out of a lens , if you own one of these lenes i would not recommend carrying it around on a tripod which i did do a lot of , and with the lock working half the time , i think this added to the problem for the lens would retract and extract on its own and not knowing this must have caused wear and damage internally , I don't think this is a work lens , after owning it and what has happened to it , keep it in is protective case until use , but then if your shooting wildlife with it like myself , animals don't tend to stick around long and wait for you to set up .

you found the right thread but start reading my posts starting back in July of 2019:


DFA 150-450mm needs repair - PentaxForums.com

the posts talk about my experience with my Pentax 150-450mm zoom when the screws stripped and the part containing the optics separated from the controls section

bottom line I suggest you call Phototronic in Topeka Kansas

http://www.phototronictopeka.com/


he was able to help me with my problem

mine was out of warranty

the cost of repair was less than $300 [ but I didn't have to pay for any shipping ]

no contact was made with Pentax because it had no warranty and I bought it from a previous owner a couple of years before the problem arose

Thank you so much for your help and detail that really helps me realize we had the same exact issue. I am a bit of a do it yourselfer whenever I think itís not a huge problem or if it looks simple enough and I am almost keen to try and fix the issue myself but I canít get a hand on the blueprint or a diagram of the whole lens assembly like I have found on other lenses. If anyone has found one I would really appreciate a point in the right direction. If I can perhaps fix it myself before going thru the route you pointed me on perhaps I can save other a huge trouble and cash. I am happy to be part of the Pentax community and itís so great to see all the help provided this community is awesome.

thank you aslyfox if this lens cost any more than $500 Canadian dollor to repair they can toss it in the sea of Japan . Dont want to sound negative, but from the reviews i have read on this lens , where everyone loves it , noting but junk as far as I'm concerned , if repaired will be going up for sale ASAP .

I really hope the repair is not too expensive. I was in a similar situation in the past and it wasn't fun. Keep us posted!
