Notice: Tamron issues product advisory for its 70-180mm F2.8 Sony E-mount lens

My lens was affected as well. But mine was because there is an issue with the AF motor. Tamron provides a return label, at least in my case. Now getting one back in a timely manner? That's another question. IF they even have a lens to give to you. They are in short supply because they are selling like hotcakes.

Yep. My Canon 200/2.0L also was recalled.

Mistakes happen. Sounds like they are responding quickly and communicating openly. Not a few manufacturers have denied problems or delayed dealing with them.

Tamron responded very quickly and honestly. I appreciate them for that.
My 24-70mm GM lens was decentered badly. Very badly. I sent it back, received a new one and it was better but still was decentered. I went to the shop myself (120 miles from where I live), asked to try a new copy. The copy I tried had noise in AF motor. Gave the lens back for a full refund. I know that good copies are excellent but so much copy variance is too much for me.

nexUser, I did the same for a Canon 16-35 and the first 3 were decentered. The 4th one was much better than the other 3.

70-200 f4 L, rear focused so badly it must have been like -30 AFMA.

Not enough characters left to tell all my Canon decentered lens stories...

Canon has never even attempted to repair a decentered lens. They clean it and send it back stating it is within tolerance.

The thing to take away is that all these lens makers tolerances are too high.

Great designs by engineers ruined by poor factory tolerances.

@xeppelin. Zeppelin Fan?! :)
Anyway, Tamron noticed an issue and they are working on a fix. Either with a firmware update or a replacement for the lens, like in my case. Their customer service is top notch and on the ball.

As for the 70-180 f2.8 quality wise. It is one very sharp lens even wide open. In the beginning the AF was quick. Last week I started noticing an issue. Thought it was just user error. Two days later I get a call from the place I bought it from and then 20 mins after that call a Tamron West Coast rep called me.

yes, i do like Zeppelins. :-)

sounds like you got really good customer service. Totally unthinkable in my part of the world. From any camera/lens company. At least outside of their professional service loop (CPS, NPS, etc.)

yes, I also like Led Zeppelin. :-)

Shooting Nikon I am sure you're used to the protocols of recalls already so I am sure you know the answers.

🤣

“Anguish”. It depends. Hopefully Tamron is covering shipping charges both ways but I don’t know. 1% problem is a problem for 1% of the people. For 99%, they put their serial numbers in the web page, find there’s no problem and move on.

It’s a hassle for those affected. Anguish is a little bit much.

Some restitution compensate should be given. A free uv filter would be a nice gesture. Or how about an extra hood?

Dont forget that when a person is not happy they can be a bigger headache for a business through social media. So a small $20 (cost to them) its a cheap price to keep your customer happy. And to have them consider future product purchases. The customer doesn't have to go through this headache because the mfr didnt calibrate properly... aka new workers

I did have an issue with the piece of garbage sb900. I then sold all 4 flashes and no longer buy any nikon flash. So a mistake like that cost them reputation and profits from me. Expensive mistake for them. And me for buying

Years ago, I purchased a limited edition (numbered) agv flagship helmet. Only 1000
Within 8months the graphic overlay had bubbled from rain & the visor was very bad quality
I made videos & didnt post them. I contacted the mfr&asked for a colored visor as a good gesture. He declined & replaced my helmet. I then posted them. Had many views/comments & even other videos commented on them. Suffice to say that the very least a $20(cost to them) visor cost them a few thousands in lost sales when people viewed the helmet defects
Its worth to throw a small gift in to keep the customer happy and that he may be a future buyer.

Just like rebuilding an engine is never the same after opened then when it came from The factory, its the same with the lens. I hate the idea its re-opened & messed with when it leaves the Japanese factory. The us is not the factory & who knows if they follow protocol to the T & have the exact instruments or are just doing a "good enough" job.

1% for Tamron but 100% for the owner.

Compensation? What? Just send it in if needed and get it fixed. No drama. No tears.

@iorep - the general rule is that if someone sells something that is defect, then they have a certain time to fix it or replace it without (direct) costs for the customer. And - that is it.

You are, of course, right that this way of doing it does affect the ones that get defect goods negatively. And - we could have the rule that there have to be a compensation. But - we do not have that. For reasons. One reason is that it is cumbersome to administer. Another reason is to protect manufacturers. They already have costs with fixing and replacing and compensation might be too much for many.

So, no - there usually are no compensation. And as a customer that sometimes do not feel fair. You bought something to use it, not to mess around with repairs etc. But, that is life.

Lens Rentals open up their lenses all the time... I've yet to see anyone complain about that...

@io rep - compensation...really??

I'm just happy when manufacturers acknowledge a problem and take responsibility to fix it at no cost to me.

On the other hand, maybe Im just a simpleton.

People just want stuff for free. Never heard of compensation for correcting a defect. I have had to bring my cars in for recalls several times and never got a free tire for my trouble. You get the fix. SOP.

Takers like io rep are the reason why service in the retail industry gets worse every year.

@Eric Hensel
As someone who does work in retail, people like this are rather annoying. I totally get that it’s annoying to return things but, that doesn’t give a pass to demand things that they’re not entitled to. They’re generally massive asshats about it too.

Interesting that you feel the need to invoke your moms medical condition to justify why you don’t have time to stop at the post office to send your lens back for a free repair. Anyway. Given your general trolling comment history here I’m not surprised.

Hope your mom is recovering well.

If you assume that it's affected a contiguous range of serial numbers and not random numbers you could use much more efficient search algorithms. Even a binary search would make quick work of that.

I guess it is very few, like 10.000 or less. So, binary search is probably not efficient. But, you could probably take every 1000, making it 1000 times faster (if the series is 1000 or more). You could also do an "HTTP HEAD" request. Then you would get the size without downloading the body.

It not contiguous.

If not, then all need to be searched.

But, how do you know?

@Roland Karlsson: Why do you need to check all that, if you own the lens, enter that lens number to know, if not why bother.
Totally ridicules to search for how many lenses are affected, what or why would that help anything?

@MikeRan - OK. Then maybe you know what series numbers are affected? Or do you know of some samples that are affected that are spread here and there?

@CekariYH - I am just a programmer that likes to solve riddles. And this riddle is solvable. And I am little curios to know why Tamron simply do not tell the lenses that are affected, instead of having this tool.

Now, there might be several reasons why Tamron do not tell us the list.

* It can be, due to what MikeRan tells us, that the serial numbers are not contiguous, and therefore a very long lit needs to be published, which is cumbersome.

* It can be due to that Tamron do not want us to know how many it is.

* It can also be due to Tamron not wanting to spread a list of bad lenses, that might make the lenses have lesser value, even after fixing.

* Or, Tamron simply do not want to support this upgrade forever. When they take the tool down, no one can check if they have an affected lens.

* Or, anything else ...
