Has anyone tried or even considered the Chinese under-£100 85mm f/1.8 primes for hobbyist/non-pro photography? Of course, they are only manual focus and build quality will not be as good as their branded counterparts, but I was wondering that at ~20% of the cost, how good is their optical quality in comparison - 70%, 80%, 90%? I could not find ratings or reviews anywhere.
Nikon 85mm f/1.8 eBay £96.99
Sony 85mm f/1.8 eBay £89.98
Update: To clarify, I am looking for a Sony FE mount lens for casual portrait photography. I posted Nikon example too as I am assuming both will be comparable in quality and someone's experience with it may help my decision.
