Another positive aspect of the SB-910 is color plastic filterswhich are very easy to install on the SB-900 were gelatin filterswhich are rather inconvenient to install on a plastic diffuser. I have found that if I place a flash in the next room, the flash sometimes does not fire and there must be a clear line of sight.

I have an oldish set of Phottix manual triggers that are still super reliable on the Z bodies with the SB-910. Please Note: The RF Wireless capabilities are only supported on the newer Nikon DSLRs (D850, D500, D4/5, and Z cameras with the optional RF transmitter. The inverter (power supply) for the cyan-green electroluminescent (EL) LCD backlight always makes a bit of a whistle when lit.Impressive about the SB-910 are its prodigious power output and super-fast recycling: 2 seconds at full power as actually measured with Sanyo eneloop cells taken right out of the package as delivered (not charged by me). Using the Newer RF WR10 you will find yourself in the camera menus to adjust groups and output which is a bit cumbersome, Maybe in the future, a dedicated RF SU800 will be offered that has the same dedicated push buttons and LCD readout as the SU-800. The SB5000 can use traditional Nikon CLS IR, Pair with a WR10 or use with a 3rd party compatible setup. I hope someone out there in an Attorney General's office is reading this, and can give Nikon the hard time it deserves: on page B-7 in the large Nikon SB-910 User's Manual, you'll see that Nikon suggests that you change the batteries when they take more than 10 seconds to recycle (20 seconds with Alkalines), while Nikon's published battery life numbers are made while waiting about three times longer to recycle.

Speaking of batteries, when are we going to get the option of rechargeable Lithium battery cells, like we use in our DSLR bodies? With the Nikon SB-910 it’s almost magical how it can pick up your flash settings and knows when to fire even when the line of sight is lost. We've been using a full production version of this 120 fps sports camera, to see what you gain (and, perhaps, lose). And when I’m going for that last little bit of subtlety in my bounced light, I prefer to bounce just a little bit to the left or right, which currently means that I gotta swivel the flash head alllll the way around the front.The SB-910 flash is heavy - 410 grams, such a flash will be rather inconvenient to use on a younger line of cameras, such as Nikon D40, D40x, D60, D50, D3000, D3100, D5000, D5100 etc.
