Get your Sigma Lenses (Canon EF mount only) up to date. Upgrade the lens firmware to improve the lens performance.
You have 2 options:
#1.
I upgrade the firmware for you in my garage by appointment.
One lens firmware upgrade is 10 dollars.
Two lenses firmware upgrade is 15 dollars.
Three and more lenses firmware upgrade is 20 dollars.
#2.
You do it yourself at your home, but you need to pick up and return it to my home. (Like a rental)
80 dollars deposit.
The cost will be 20 dollars for EVERY 24 hours.
You can also use this dock to fine tune your lens, if you know what you are doing. (https://www.sigmacanada.ca/en/sigma-usb-dock)
*** For returning custmoers, all the cost is 50% off. Verified by your phone number. ***
PLEASE PLEASE PLEASE check your lens firmware version on your camera body first, and check the latest firmware version at sigma website. Make sure the lens needs a upgrade; OTHERWISE, I will still charge 10 dollars.
