    I have a Sigma 10-20mm f/3.5 EX DC HSM Lens, but it doesnt seem to auto focus on my D7500, it focused on my D7100. Did something happen to the lens or is it not compatible?
     
  2. You might have to send the lens to Sigma to get a firmware update if available. In fact I would contact them first to see if they do offer an update. Nikon might of done some tweaks with the D7500 making older 3rd party lenses incompatible.
