Yes
A friend of mine bought the Sigma 30mm f/1.4 EX about 9 months ago. He was very happy with the lens until recently when it started backfocusing really bad. I checked the lens and it looks defective. The problem is that he bought the lens from OneStop-Digital. As you may possibly know, OSD is a HK based company who have a good reputation of avoiding customs. They have a very good costumer service and good reputation but will he need to send it back to them or since it's still under the one year world wide warranty he'll be able to fix it here in the UK?
 
If you have a read at the warranty you'll discover that it's only worldwide insomuch as the same warranty applies everywhere, the lens has to be returned to the country it was purchased in for service/repair - Sigma UK will only do the work if you can provide a VAT receipt. - which is why I stopped buying Sigma lenses from overseas and spend the wee bit extra on UK ones now...
 
Thanks for that! I'll let him know but I don't think he'll like it :p
 
Personally I don't think its worth importing Sigma, as you only save by importing if you avoid VAT - which makes the warrenty worthless. Paying to send it back to HK, or paying Sigma UK to fix for the most part nullifies any upfront savings.

Sigma UK may just do it anyhow, if not they will send it back to Japan for you (several weeks). They are nice folks at Sigma UK so they may turn a blind eye...
 
Thanks everybody! I'll email him this thread! Good thing my sigmas are working just fine, never had any problem with them!

Sigma HK will do it but you need to get it there.

The 3 Sigmas that I have bought in Hong Kong and Tokyo (15-30, 80-400, 12-24) all have international warranties that would be covered by Sigma UK.
 
In order to get a warranty repair Sigma will want to see a receipt, if that doesn't show duty/vat they will probably refuse the repair as it's a grey import but I have heard that some people have managed to get away with it - probably depends on which person at Sigma checks the receipt.

Yes, but the OP said he got it from a place with a good reputation for avoiding customs charges - therefore I took it as not having paid import duty/tax. Read the 'truth about grey imports' message on Sigma UK's website...

Sigma UK are excellent they stripped my siggy 400apo cleaned the optics and reset the lens for £74 inc delivery tel 01707 329999
And they do warranty work
 
Excuse my ignorance guys, but by back focussing, do you mean the camera is saying it's focussed on a certain point but it's actual focussed past it?

If so, I'm experiencing that with my f/2.8 70-200mm. My D200 is saying he focus is spot on but when I enlarge, the focus is actually behind the subject, so it looks slightly fuzzy. Should I be taking it back to jessops of contacting Sigma direct?

Or is it a prob with my D200?..
 
Yes, back focus is where the lens is focused beyond the intended point. AF is normally an open loop, the camera tells the lens what point to focus at and the motor moves the lens to the right point - this isn't checked, just assumed to be right (hence open loop). Servo mode is sort of closed in that it's constantly checking and a really bad front/back focused lens might never settle in servo mode as a result.

Could be the body or the lens or both. They're built to a spec of +/- spot on and if you've got a lens that's -5 and a body that's also -5 you get a result of -10 but the spec might say -5 is the limit. Sometimes both body and lens need calibrating.
