Ryan Brenizer has a succinct review of the new Nikon SB-910 Speedlight. It looks like a great speedlight, as expected, except for the new $100 added to the price. The best new “feature” of the SB-910, for me, is that it convinced a bunch of people to sell of their SB-900s to upgrade. My SB-900 has been great, so I picked up a second one in excellent condition on the used market for $300.
