My sister-in-law recently purchased a D5600 (body only) to replace her D5100. She has the kit 18-55 from the 5100 and an older Sigma DG Macro 70-300 f/4-5.6 Unfortunately, the Sigma will not auto-focus on her new D5600.
She took the body and lens to the local shop she bought the body from, but the sales person only tested a different D5600 and had the same problem. The Sigma works fine on the older D5100 and the 18-55 works on both cameras. I remember reading that other firmware "upgrades" have caused lens and battery issues in the past. There do not seem to be any other reports online of these issues. In fact, everything I have read indicates there should be no difference in the list of lenses which will AF between these two bodies.
Does anyone know of other issues with third party lenses no longer auto-focus with the D5600? Should she contact Sigma in this case?
