Been having problems with back focusing with the Sigma 120-300 2.8 lens.
Target point out of focus and capturing 12-18 inches back from this.
has anyone had similar problems with this sigma lens ?
Has anyone had the same problems with the 300-800 lens ?
What experiences have people had with the Sigma service centre with related issues ?
Apologies for the number of questions but as you can imagine I would like a rough idea of what I am in for, in respect of standard of service !
