8/31/2023 0 Comments Sigma lens customer serviceThe range between numbers of the same f-number is the depth of field. These figures show the depth of field for each aperture setting. The depth of field scale is printed on depth of field scales on the right and left sides of the centre index line. Depth of field region can be determined by combination of depth of field scale and distance scale. For example on a 28-80mm zoom lens W is equal to 28mm and T is corresponding to 80mm. So if you're curious, you may want to go ahead and give Sigma Service a call.W indicates wide focal length and T indicates telephoto. However, when he called Sigma to inquire about the repair, Sigma gave him very detailed information on what they had done. Update: Site visitor Don let me know he had a similar experience - a fairly quick turnaround with no formal communication. And at any time, I can also check the status of my repair on their website.īut when the crickets are chirping, you can rest assured knowing your item is very likely being repaired and returned in a timely manner. Then they send a shipment notice with tracking information when my item leaves their service facility. They send me an email when they begin processing my repair. When I send an item into Canon Service, I get an email showing that they received the item. A recent "rush" repair order to Canon Professional Services took longer.īut Canon's Repair Service trumps Sigma's in a big area - communication. Considering that they received my lens on the 24th and had it back in my hands on the 30th suggests that Sigma has invested a significant amount of resources in making service and repair orders a priority. On the one hand, Sigma's turnaround time was fast - very fast, in fact. The paperwork with the lens suggested that a circuit board had been replaced and the firmware had been updated by the Service Center. Before I gave them a call, however, a FedEx truck arrived with an unexpected package – my lens. On October 30, I had an entry in my calendar to give Sigma a call and ask for a status on my lens repair. Sigma never sent me a return shipment notice. There was no way for me to check the status of my repair online (that I could find). They never sent me an email to let me know they were processing my repair. Sigma never sent me an email to confirm that they had received my lens (I got the delivery confirmation from FedEx). The Issue of Communication (or lack thereof) On October 22 I packed up the lens (including the appropriate repair forms with contact and warranty information) and shipped it to Sigma's Repair Center in Ronkonkoma, New York. Sigma's technical support adviced me to send the lens in for repair. After several failed attempts at getting the firmware update to stick, I called Sigma's technical support. And every time I chose to "update" the firmware, the autofocus adjustments were reset to "0."įor some reason, the lens was reporting that it had the original stock firmware installed. If I chose not to update the firmware, Optimization Pro would make the focus adjustments button inactive. Every time I would connect the lens to the USB Dock, the software would insist on upgrading the lens's firmware. Even though my lens had been updated with the newest firmware a month earlier, Sigma Optimization Pro was insisting that my lens wasn't up to date. Sigma had not just released a firmware update. I thought to myself, "What a coincidence that Sigma would release a lens firmware update during the hour I'm adjusting this lens." After about four cycles of adjusting values and focus testing, I connected the lens to the USB dock and Sigma's Optimization Pro software told me there was a firmware update for the lens. I made several different focus adjustments and tested the lens after each one. On October 21, I was using the Sigma USB Dock to dial in focus adjstments on my 35mm f/1.4 DG HSM Art lens.
