SDM issues? A straw poll.

There has been a long history of posts about SDM failures on DePressing Review, which has become very heated as people are worried about SDM reliability, but none here as far as I can see, which I find somewhat curious.

If you have an SDM lens (or several), please can you answer the poll and if you had any failure(s), post which lens or lenses.

Please, this is for SDM failures only.

I will kick it off with my "No"

Many thanks.

I have 3 SDM lenses and all work fine.

Hi Peter

That's great, pleased to hear that, can you tick the box for me? Ta!

1 lens for 9 months (17-70). No problems so far.

1 lens 7 months (17-70) no probs.

3 lenses over 18 months no issues.

3 lenses 2 of the alleged problematic dual drive

1 2 years old (16-50)
1 12 months old (50-135)
1 4 months old (55mm)

Pity the Poll can't ask how many lens you own .

Since Dad never posts here, I'll report his for him.

A 50-135 blew its SDM and fell back to screw drive, when we had the lens repared we discovered that the camera's (A K10D) SDM drive workings were also knackered so that had to go in for repair too. No idea if it was coincidence or if one component blew up and took the other with it, but both ended up in the shop.

DA*300mm for 18 months no problem.

Dan

DA*50-135mm two years no problems.

Thanks for your response, much appreciated. Were they under warranty or not and how much was the repair if not covered and how long did the repair(s) take?

So far you are the only report of faulty SDM, but there are 2 failure reports. Did you include the body as well?

If not, we have an anonymous post.

I did request that people identify the lens if they had a failure. Would appreciate no anonymous "No" responses, "Yes" responses don't need identification, though it is appreciated if you do.

DA* 16-50mm, DA* 50-135mm and DA* 60-250mm .. no failures.

Saying that the last 2 are only a few months old anyway, the 16-50mm was bought used off Ebay but has hardly been used.

DA*50-135 and DA17-70.
No problems at all.

3 lenses in 18 months and no failures.

Hi Richard,Just sent my 50-135 back to SRS.SDM has been ''iffy''for a while and recently completely failed.Hoping for a speedy resolution. Regards Tony.
