Highly recommend LKN.
I purchased a Nikon Z-6 with FTZ adapter, and spoke and dealt with Dr Lim directly. He was more than helpful in finding me the right product at an amazing price. LKN is also an authorised reseller for Nikon meaning I was given assurance of warranty and a factory sealed camera pack direct from Nikon.
He also kept me informed through out the shipping process and was quick to respond.
Will be coming back for more.
