Either way, it’s there if you want to get in line and take it for a test drive for a few days. A three day rental will run you just under $400 and a 7 day rental will set you back about $540 (includes insurance).
On the Nikon side we’ve had an interesting couple of months with both the D4 and the D800 launching just a month or so apart. I know many of those that pre-ordered their D4’s have been waiting patiently for it in the mail.
This update by Borrowlenses indicates it’s likely those shipments of pre-orders from other online retailers will happen sooner rather than later.
While you’re at it, why not rent it along with the Nikon 400mm f/2.8G ED VR II! That should make for a cool combination, take great pictures and make some head turns at the same time. Or just buy the lens and be the king of of your photo group! 😉
Finally, also updated the Nikon Buying Guide with the correct link to the D4 rental. Plus several times a week I update that page with any updates.
