If you want a retailer who communicate quickly, is honest, up front and well priced LNK are a great place to shop.
I don't know if LKN normally accepts trades but I was able to agree on a price over the phone, even though I thought it was on the low side. They where not interested in all the lens I wanted to trade. I had to send my lens via mail from Central Queensland and wait for an inspection before the price was confirmed. My trade in lens was in great condition, in original packaging. Even though the trade in price was on the low side I guess LKN where happy with the lens. Rather than say its worth another $100 they offered a $100 discount and free freight on the Nikon Z 105mm Macro which was already competitively priced. This discount was not the Nikon $100 rebate that was also available as LKN is an Authorized Nikon Australia retailer. ( I have already received my $100 from Nikon. That came through in less than a week ). The Z macro lens are under supplied and I had to weight for stock . No one, not even Nikon had stock, so no big deal. I had my lens exactly when I was told it would be available.
At the time of this review, LKN have the Nikon Z 105mm MC as sold out and Nikon have them as a Pre order on Amazon which also means they are out of stock.
Lim at LKN was not obliged to offer me a discount, we had agreed on a price, and certainly could have probably sold the New lens several time over without a discount. I can imagine at times people over estimate the condition of their second hand lenses and hence the cautiously low trade in offer. But my experience is if you are fair and honest, Lim at LNK is fair honest and kind.
