Great gear that is hamstrung by something they need to address head on. I would hope in your case, the lens is replaced.

This is bad news.
The reputation of a fine brand is at stake, and the staff at Pentax are just.....


I don't blame you ironcorn. If you can afford it, the competitors can offer a little more reassurance in their gear (not that they're completely fail-safe, though).

But these repeated SDM shortcomings continue to tarnish the brand and turn away users who would ordinarily be happy with Pentax gear. Andi, there will be more and more apprehensive users as yourself, and Pentax's head in the sand response will only hurt them more, but I'm hoping... praying... that SDM will be sorted out, and we'll see a resurgence of good lenses out there being used by happy owners...

Luckily I dont have a real need for the DA* glass right now and on the other hand really enjoy primes. If I do end up needing a high-end standard zoom one day, I'll probably end up running two systems, which is a real pity!

Hi,
I just mailed my DA* 16-50 with dead SDM in today. It had three weeks of use followed by four weeks of shelf time. I bought the lens new.
I called Pentax to complain and was transferred to an office above customer support. I talked with a gentleman and expressed my concerns about the long term reliability of the SDM. He wouldn’t engage in any real conversation concerning the SDM, nothing, he just kept interrupting me, telling me to check out dpreview because Pentax (according to him) had posted some numbers on this site which dispelled the idea that there was a high failure rate of SDM. He stated that the overall failure numbers were actually very low AND mostly caused by the lens hitting something, often while in the camera bag. I’m not happy and am considering a brand change.
If this is true (I have no reason to doubt you other than cautionary web forum skepticism) it makes me very angry. Blaming the customer? I can assure you that the SDM failures I had on BOTH of my DA* lenses, had absolutely nothing to do with the lens hitting something while in the camera bag or out of it! Unbelievable that he would send you to DPreview for confirmation. There are many threads over there that have been started by people upset with the quality control of DA* lenses.

I baby my lenses. If they are not on the camera, they are in the pouch they shipped with, and safely in my "lens cabinet" in an air-conditioned office. My camera is also always very well protected. I find it odd that NONE of my many other Pentax lenses, NOT A SINGLE ONE, over the decades have EVER failed in ANY way. And certainly not "due to hitting something while in the camera bag."

We have flown two different lens types on the high-altitude research balloons. One was an 18-55 kit lens, the other was the 10-17 fisheye. They hit the ground at between 20 to 30 mph inside a protective cardboard box, somewhat similar in padding to a camera bag. No damage whatsoever to the lenses or cameras. (Note that both of these lenses use screw drive.) Yet these new DA* lenses are so fragile that a simple bump while inside a camera bag is knocking out the SDM motors? If that is the case, then Pentax is sure going the wrong direction in creating a "ruggedized," weather resistant brand for outdoor enthusiasts.

wow.

We'll see what happens. I am not too deep into Pentax digital as I have just, finally, made the switch from film. I have a K20D and the 16-50. I went with Pentax as I have always used Pentax film cameras.
I was just getting ready to buy a DA* 300 and DA* 50-135 for an upcoming trip when the 16-50 acted up. I found this website searching for an answer to my dead lens.

So, I am at a pause now, considering going forward with more Pentax or jumping brands. What I was looking for when calling Pentax were some words of reassurance concerning my prospective lens purchases. I did not receive that.

I had only used the 16-50 on one trip. It worked fine, although a little soft (I'm reading that there is this additional focus adjustment between the body and the lens that you can make). Overall, digital is pretty exciting, so I'm going to stay positive.

I suggest that you return the lens, get your money and buy some LTDs instead. eventhough they are not as versatile as the zooms, those would surely keep you more than happy. 3 small LTDs is equal to almost a 1 big DA* zoom in size, except the LTDs are much lighter even when combined. the lenses I would suggest is the DA15, DA21 and DA35/DA40 or FA43.

Yes the LTD's are fantastic. I love my 70. It is fast, reliable, and very well built.

Yep, I'll second the FA or DA limiteds - they're all awesome and worth the money - if you can afford them. But it's no excuse for an overpriced DA* lens to die - fortunate for you it's within warranty period, and you *will* either get a replacement or a refund. I wouldn't sway you either way as I'm reasonably happy with my 16-50 used very often for over a year now. It's sharp, with beautiful microcontrast with the only glitch being infinity distance focus hunt, which is quite stupid but tolerable... only just...

over the weekend I mounted my Pentax DA 17-70 SDM only lens to my K10D. It's been a great lens so far (bought new in August), however, this weekend it couldn't lock focus.
Oh noes! I was feeling so safe with my DA 17-70 because I had not seen reports of SDM failure with this lens... and now you wrote some bad news
I had no problems with it so far, I hope there won't be any in the future either.

If you are going to have in lens motors, they have to be sturdy enough that you can use them. At the same time, I had an SDM failure and it definitely was not the result of any trauma to the lens. Just one weekend, the motors began to struggle to turn the lens elements. At the same time, I have a 50-135 that is over a year old and has never had any problems (and is heavily used).

As far as on DP Review, the only thing that I knew was that John Carlson had posted there that he would "look into it," but I never saw anything further. I guess the question is really one of expectation. Consumers have the idea that roughly one hundred percent of lenses should work for a minimum of four or five years (and preferrably for much longer than that). Pentax just really wants to get them through the first year, one way or another. Once they are out of that first year of warranty, it just isn't Pentax's problem.

But it really is. I don't see why they can't see that if there is a lot of trepidation about SDM, that it will hurt sales, not only of the lenses that have it, but will bleed over into camera sales and lenses that don't have it.

I couldn't find that thread, but I did find these.

This situation is really, really disturbing. First the 16-50 issues and now this SDM mess.
I need a @50-135 fast zoom for work at home (small town PJ stuff) and have had my sites on the DA*50-135 for awhile. I said elsewhere I'm going ahead with it this week and hoping for the best.
I would definitely contribute to a sticky thread/DB of serial #s for this lens.

cheers

I thought I was safe too because it wasn't a * or SDM/Sd combo. I've never used a * lens before but I've sure enjoyed my 17-70 up to this point. I thought if they built an SDM only lens they'd do it right, and I hadn't heard any reports of problems either.

Well, I'll keep you posted on how Pentax handles this lens.
