    Posted: 08 January 2022 at 18:42
Hello, i bought a new Sigma and Tamron lens and both of them are authorized for 5 additional years of warranty after registration, but after reading Sigmas guidelines i wonder if the warranty even covers failures of the AF-drive?

What Sigma says:
"This warranty does not include the repair, maintenance or replacement of components, which are damaged or worn out in the regular course of normal use."

In Tamrons box i couldn't even find something mentioning this, but only the regular instruction manual of operating the lens.


The only possible lens failure to my thinking is the AF-drive.. which could maybe be not included by warranty as it is "in the regular course of normal use".

Does someone have experience with this?
Thanks.

I have no experience but would not interpret it that way. The AF motor is not a consumable like a battery, it would be exceedingly surprising if it were not expected to last for the warranty period.

Tamron's warranty sounds a bit more forgiving: https://www.tamron.eu/fileadmin/user_upload/Service/5yw%20terms/Tamron-5years-Terms-UK.pdf :
"..will remain free from defect during the agreed warranty period if used and
serviced properly. Should product turn out to be defective during the warranty period,
TAMRON agrees to either repair or replace such product free of charge,"

than "are covered for 4yr USA warranty against defects in manufacturing and workmanship only" (Sigma US), though I think they mean the same thing.

It doesn't matter what they write on their website, you are covered by the European union consumer laws when bought in EU (I assume you bought them in Germany). Your lens should be fine within a reasonable time - usually considered two years. If your AF drive fails within that period, it should be repaired imo.

In fact the German Sigma site mentions:
Sollte das Produkt während dieser Garantiezeit infolge eines Material- oder Herstellungsfehlers Mängel aufweisen, wird es von uns kostenfrei nach unserem Ermessen repariert oder durch ein mangelfreies Produkt ersetzt.
and
Die Garantie erstreckt sich nicht auf Schäden, Mängel oder Funktionsstörungen, die durch Bedienung entgegen den Vorschriften der Bedienungsanleitung, unsachgemäße Behandlung, Stoß, Fall oder Verunreinigung, durch z.B. Feuchtigkeit, Sand, Staub, Schmutz oder ausgelaufene Batterien entstanden sind.
https://www.sigma-foto.de/fileadmin/relaunch/service/3-Jahresgarantie_April_2021.pdf

It doesn't mention AF, at least, I could not find it. It says it covers production faults and not if you misbehave. Quite normal warranty rules imo. And like I said, if it is violation of the EU consumer laws, those laws are still applicable.

A month before the 5-year guarantee for my Tamron 28-300mm expired the AF broke. Tamron came up for the repair (new AF motors) without any ado. I sent the broken Tamron (together with the paperwork) to Geissler. They handled it flawlessly! Hard to imagine that Sigma follows a less customer-friendly policy.

The procedure to send in a Sigma lens seems to be very similar with the procedure at Geissler - as I learnt here.

Tell us how it worked after it is returned!

Alright, this sounds very promising and worthwhile to register for the additional warranty.. just for savety. Thanks.

One more question: I almost exclusively buy lenses 2nd hand from private sellers and sometimes there is a lens that has been registered by the previous owner for additional warranty - does it cover successful warranty only by the original person who registered it, or also me, who now also owns the lens, warranty card and paperwork that confirms the purchase?

Buying some lens that may have 4 years of warranty remaining sounds promising for a 2nd hand auction, but if i am not justified to claim the warranty, as i am not the original buyer.. would be pretty disappointing.


Edit: The registration of the Tamron A-Mount lens was succesful and easy to do. It also solved my mentioned question: Only the original buyer can claim the warranty, so be aware of 2nd hand purchases. I bet it will be the same for Sigma or other brands.

Not for Sigma's products in the Nordic countries:

https://www.sigma-imaging.se/extended-warranty-registration
"Since the warranty is tied to the product and not the owner, it will still apply even if you decide to sell the lens or camera."

It isn't so for Tamron in Europe (incl the Nordic countries).

EU consumer law isn't lw but anyway:
"Second–hand goods that you buy from private individuals are not covered by EU consumer rules"

Unfortunately Sigma's German text on the extended warranty does not read as generous as that for Nordic countries: "This warranty is not transferrable." ("Diese Garantie ist nicht übertragbar.") - as you can read here. As I understand it, only the original buyer of the lens will be able to claim the warranty.

BTW: Sigma only grants an extension of the warranty to 3 years, not - as Tamron - to 5 years. Or did I miss something?
