S5 front focus, need help
Send body and lens to Sigma service, thay shoudl be able to adjust lens to body.
Sigma has special device for adjusting HSM lenses (confirmed with authorised Sigma service). I suggest calling them first wheter specific service center has this device.
I have problem with 2 lenses, (30/1.4 and 50-150) I plan to send them for adjustment. I just need to test S5 with Nikkor 50/1.4 to verify if it is not problem also in S5 body.
