Tamron SP AF 17-50 mm f/2.8 XR Di II LD Aspherical (IF) - fault

From new, this lens has periodically stopped working. I've asked about it previously but couldn't find the thread. What happens is that in the middle of taking photos, the lens suddenly appears to be a manual lens to the camera. I've had to take the lens off and put it back on in order to get it to work at all once the issue occurs. Previously I thought that it was an incompatibility between the K3 and the Tamron, because I never had the problem on the K5ii. But over the last few days I've found that zooming from 17mm to 50mm seems to trigger the problem. Zooming in and out a couple of times seems to fix it. I wish I had found this out when the lens was under warranty,

Could be a very small misalignment, a loose or faulty wire, etc. Doesn't Tamron offer a 6-year warranty?

I don't think that the warranty is that long in Hong Kong. Unfortunately I bought the lens from HK and I live in Australia which makes a warranty claim pretty much impossible. Lesson learned about the disadvantages of buying from a cheap overseas vendor.
PS Thanks for the suggestion, Adam!

I guess the only redeeming factor would be that the lens is really cheap now that it's on closeout.

I think I'll get a Pentax 12-24 or even the Pentax DA*16-50. I've had no issues with my pentax lenses, although in general the Tamron is great.

I've changed from the Tamron to the DA*16-50. The DA* has a much better in build quality, but it's huge and the flare resistance can be a problem. With the Tamron I have never considered flare, becasuse that was perfectly resistant.
IQ wise the Tamron was better by a liitle, but the focus problems made the results worse in general (I've used with large aperture on events).

Thanks for the info! Optically the Tamron is good, which is surprising for a relatively cheap lens. Now that I know I just need to adjust the zoom until it talks again, it's not so bad.

I really wonder whether it's a problem between the K3 and Tamron lens, but nobody else has reported it. I'll probably have to try using the lens on the K5ii for a couple of days to see if it still happens.

Speaking of Tamron in Australia, just FYI, they were distributed by Maxwell locally for years. Then in March 2016 Maxwell closed down in Australia, and Tamron brand distribution was handed over to TNS Connect. An arrangement which didn't last long, as TMS Connect soon dumped their whole photo division, including Tamron, so in November 2016 Tamron appointed Blonde Robot exclusive distributor for Australia:

Maxwell to end operations | PhotoCounter
Tamron moves to Blonde Robot | PhotoCounter

This bouncing around of distribution does not give me great confidence in local support for the brand, so one may as well buy overseas. I got a 4 year lens warranty on a Tamron lens purchase from Maxwell in 2016 - 2 years standard warranty + 2 year bonus warranty extension upon registration of purchase - but that was two distributors ago now. Who knows if anyone will honour such a warranty anymore.

Having said that, the Tamron local distributors have always used Hartland Camera Repairs in Perth as the official Tamron repairer in Australia, so that hasn't changed over the years.
