Played the Sigma lottery and lost.

Sigma 30mm 1.4 - arrived today. Front focusing like an insane amount. I used teamspeed's DIY focus sheet. (see attachment below). I focused on the bottom curve in the S. EXIF data is 1/320, f2.0, iso200.

Should I return to Amazon and request another? Or go with Sigma warranty and send it in for calibration? Will they need my T2i body to calibrate it?

Any other suggestions?

Try it at a different distance. If the front focus is consistent, send it to sigma. If you get different results at different distances, exchange it through amazon.

But thats quite a big focus error. Have you tried repeating the test? Maybe do a battery test for the sake of variety.

And the battery test. Wow. Really not even close. 1st is a slight crop. 2nd is a crop with batteries 2,3,4.


So which - Amazon return or Sigma?

Send to Sigma, You potentially save yourself time dealing with getting another copy like yours.

What's the full process? Register w Sigma warranty then call them?

I'd send it to sigma along with the photos in an email or printed out, so they know exactly what the problem is.

I'll post a thread about this in a day or so when I get my lens back, hopefully in good working order, but I sent my sigma 50 in last Wednesday. Was received by sigma Friday. I called today to verify they got it and the said it had already been calibrated and sent back. I should have it today or tomorrow. so far so good...

arctic98z - can you let me know how it goes? Did you send yours straight in (Ronkonkoma, NY 11779 address)? Or to a service center?

With the Sigma's it may be better to buy used on craigslist or whatever, you can test in person then

Bummed.....at this point I'm wondering do I return to Amazon and pour the funds into a Canon 17-55. Was considering the Sigma 17-50 but now this transaction makes me nervous.

Yes I sent mine in to NY. I did not send my body however, FYI. I'll keep you posted. Been a smooth, quick process so far. Hope I'm not speaking too soon.

As for buying used off CL or any other means, I think you run the same risk, minus warranty and customer service. The lens might have worked great for them on their camera but what about yours? Also maybe they didn't shoot wide open, pixel peep, or even care or notice if it was slightly off or soft... Not saying its a bad idea but also not a guarantee.

Order from Adorama. Speak to Helen. She has posted on the forums that she can have her director hand pick and test a lens prior to shipping it so you will get a good one.
