<p>Thank you all for the contribution. In addition to front focus issues, I randomly had blur shot at infinite under day light.... I eventually lost confidence in the product (this copy of the product) and returned it.<br> Thanks again</p> <p> </p>

<p>Hi,<br> I just bought the sigma art 35mm f1.4 ART to use on D800, and noticed a front focus issue.<br> I tested it at f1.4 on tripod.</p> <p><br /> After fine tuning the focus for this lenses to +20, it now looks ok. <br> The other lenses I have are all nikon and they focus without need to fine tune. <br> The camera itself was serviced few weeks ago and had the AF system check thoroughly, no issues were found.</p> <p>I feel unconfortable with fine tuning the lens to this amount, do you find +20 an accetable value or would you return the lens insetad?</p> <p>Thanks</p> <p>Regards,</p> <p>Francesco</p>

<p>I am looking for this lens here in the UK, I cannot find it anywhere....<br> I will try too at Calumet.</p>
