A very limited quantity of the Canon RF 100-500mm F4-7.1L IS USM is now in-stock at the Canon Direct Store (at the price of $2699.00). This lens is in a pre-order situation at all stores. Only 14 are in-stock at time of post.
It also comes with free 2-day expedited shipping.
The Canon store can be unreliable with their inventory counts, as there seems to be a delay in updating the stock info. The key is to order quickly while it’s showing a large number in-stock. As that number gets lower there is a chance the item may already be out of stock and your order may be converted to a backorder.
