I have received a Canon price list that looks pretty legitimate but can obviously be easily edited. I can’t post the price list for obvious reasons.
According to the price list, the Canon EOS R5 will have an MSRP of €4500. Keep in mind pricing in Euro also includes VAT. which can range from 17%-27% depending on the country you’re in. There are also other considerations when looking at pricing in Euro.
The €4500 Euro pricing would mean that the price in USD will definitely be below $4000 USD. As a comparison, the Canon EOS 5D Mark IV launched at $3499 USD, £3599, and €4129 in the Eurozone.
A second source claims that the Canon EOS R5 will begin shipping in early August.
