Ordering first and asking questions later is usually a good decision for any newly announced product, and that was my recommendation in the R3 announcement coverage. Unfortunately, Canon has already added that hot camera model to the supply constraint list. Worse, the two new lenses also hit the list.
A head's up for Sony users, note that all of the lens and most of the camera instant savings programs were just discontinued.
If a camera or lens you want is in stock, buy it now. If not in stock, place an order now to ensure earliest delivery. As always, using the links on this site to place order provides our necessary support.
