Both Nikon and Canon have warned users that forthcoming DSLRs will be hit by delays: The 100th anniversary edition of the Nikon D5 and the Canon 6D Mark II kit with the EF 24-70mm F4L lens are both going to arrive at your door later than expected.
According to a statement on Nikon’s website, the 100th anniversary edition of Nikon’s D5 has been put back by a couple of weeks from July 28th to ‘early August’ while final adjustments are made. The company promises to inform users of the new release date once it is determined.
More seriously perhaps, Canon has issued a statement letting hopeful shoppers know that demand for the EOS 6D Mark ll kit with the Canon EF 24-70mm F4L IS USM lens has exceeded expectations, and that orders will take some time to fulfill. The kits were supposed to ship on August 4th, but Canon has not revealed when it will be able to satisfy the initial demand.
The EOS 6D ll is also offered body only and as a kit with the 24-105mm F3.5-5.6 IS STM lens, so those desperate to buy the camera do have other options.
