I would like to thank everyone at Aden Camera for helping out to resolve a focusing issue with a Sigma 150-600mm C lens. Special thank you to Eddie Cheung, for always taking care of my needs whether it be a new purchase or a problem with equipment. The people at Aden Camera are so helpful and caring about their customers needs, they do go that extra mile to satisfy their customers. My Sigma lens wasn’t focusing at all in cold weather and Aden Camera sent it back to Sigma to resolve this problem. It did take awhile but was well worth the wait as now my lens that I got back is working perfectly no matter the weather conditions. This is the reason more people should shop at Aden Camera, they do go that extra step to help the customer. Once again thank you to all at Aden Camera for helping me out and wishing everyone a safe and happy holidays during these tuff times. One happy customer Brian Baverstock
