repair of 60-250 lens

Folks,
I have a DA Series lens and the auto-focus function seems to have about ceased operation....I presume there is a small motor in the lens that is shot (?).

Can you advise options on how to have this repaired? Is this a user DIY kind of thing for a person who is mechanically proficient, etc.?

Thanks/Bill

Assuming it is the SDM focusing motor that has gone then, no. Pentax will not sell you the part. Loss of the SDM motor on the DA 60-250 has been quite rare compared to the DA*16-50 but it has occurred. The only option is to send it in for repair.

In the USA Precision Camera Repair is the warranty repair service. However, some other shops will repair out of warranty. KEH has been advertising this lately.

There is a sticky at the top of the forum you posted in listing the available repair shops: https://www.pentaxforums.com/forums/189-repairs-warranty-service/316284-penta...e-listing.html

Sounds like the SDM has failed. Pentax made an odd design decision in that the SDM doesn't fail over to the screw drive but rather bricks the autofocus. On some of the SDM lenses, there is a method to reprogram the chip to work on the screw drive rather than the SDM, which has been discussed in various threads here. Not sure if the 60-250mm is one that can be modded, but if you search the forums for "SDM screwdrive conversion" you should find several threads discussing the subject as well as forum members offering to do it for you for a small fee.

Not that anyone has found that I know of. Someone on the forum Uncle Vanya maybe?? has been offering 16-50 conversion but I saw him post last week or so that no 60-250 conversion was possible yet.

Was the lens sitting unused for a long time? I have noticed, and others as well, that if the SDM sits a long time unused it may appear to be dead. I have a DA 17 - 70 and DA* 200 and both will appear completely dead if I haven't used them for while. What I do is turn the camera on and not try to focus for about 2 minutes. I am told that this recharges a capacitor inside the lens. If this does not get the SDM working I use quick shift on about 2 or 3 pictures. By this point both lenses, if the SDM was initially balking will start working fine. Several times I was ready to send them off for repairs, thinking the SDM was really dead, but they came back to life. I use or at least exercise the DA* 200 once every 2 months and the DA 17 - 70 every 2 weeks and this keeps the SDM motors up and working every time I use both lenses.
I hope this may be of help. Maybe I was just lucky but I have had both lenses for more than 5 years and never need to repair either one.

I'd recommend getting the lens repaired at Precision. Shouldn't be too expensive given its value.

Before you run off for a repair, I had trouble with mine. Cleaning the contacts on the lens may have fixed my problem. To early to tell.

i had the same problem with my 60-250 lens last summer. I eventually had to send it to a repair shop in Toronto where it got fixed for $CDN 250. Works fine now.

This is not a user repairable part. I had a 60-250 that earned itself an all expenses paid trip back to the factory in Japan to replace it's SDM motor back in 2010 or so. I sold it to a member of this forum a short time ago, and the AF was DOA. I'm covering that expense for him because it's the right thing to do, but it isn't being a cheap repair.
My understanding of the SDM mechanism is it needs to be used frequently to keep working. My 60-250 would sit in the bag unused for months at a time. In the 7 years I owned it, it was used for just over 1200 images, most of which were taken over a couple of days.

Yes, it has sat in the bag unused for quite some time. I've seen this occur before, the motor seems to 'hesitate' to want to drive the system. Until recently if I did try to use autofocus the functionality would eventually 'kick in' and work but not it seems that nothing is happening, I can't sense that the motor is 'trying' to work when I partially depress the shutter release. Disappointing, and to some extent I wonder if it's worth the cost of repair? Reliability going forward does not seem encouraging.

Any add'l advice? Thanks/Bill

focus TOTALLY locking up - won't even manual focus. Then sometimes it's fine. I put it on a K1, worked great, worked great on my K3ii briefly, as soon as I got it hoe it's bricked. This sucks.

Cheers,

I bought Wheatfield's 60-250mm off this forum. The SDM was hesitant at first, and then after 2-3 days completely stopped working. I tried the "recharging" method by rotating the autofocus ring back and forth while half depressing the shutter release.

It worked half a day and stopped again. My understanding is that it is a capacitor that slowly discharges over time, hence it needing to be used often.

Also, one cannot convert to screwdrive as of yet, no one has done it successfully. Only the 16-50 and 50-135 can be converted I believe.

So you can have it repaired at a substantial cost or leave it to use manually.

I'm actually quite irritated by Ricoh in this regard, in my situation this is the second time the SDM has failed and Ricoh is offering no discount/apologies. I am lucky enough that Wheatfield is being so gracious. Ricoh needs to improve their aftersales support, otherwise they will start to lose their small but loyal support base.

DA* 60-250 SDM repair

After 3 years, the SDM went on mine. Would not work in Manual either. Fixed at Canadian warranty depot for $300 CDN. Replaced with a new version of the SDM. Most of the cost was labor. Seems fine now after 4 months.
