I don’t suppose this bit of news will be much of a problem for most people. A limited edition 100th anniversary Nikon D5 is either going to be way over budget or just not that interesting to the majority of Nikon shooters. As for the 6D Mark II, it’s proven to be surprisingly popular. Surprising when you consider the early reviews and disappointments.
Regardless, both Nikon Japan and Canon Japan have announced that these DSLRs are being hit with shipping delays. Nikon released a statement that the 100th anniversary edition Nikon D5 has been delayed by a couple of weeks to “early August”. Canon’s statement cites the number orders surprissing their expectations.
