We make sure that the band.it fits on this Sigma 24-105 better than the OEM zoom and focus grips. No glue, no rubber bands, no bracelets, no loss of professionalism! Keep your lens in good shape and get a better grip or replace your OEM grips with a band.it.
You can purchase band.it for either the zoom or focus ring for $20 USD each. Each band.it comes with a 30 day money back guarantee and one-year damage warranty!
