AF Failure during Warranty

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.

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.

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.

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.

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?
