GODOX TT685C E-TTL 2.4G Wireless Master Slave Speedlight Flashlight Speedlite for Canon EOS 650D 600D 550D 500D 5D Mark III

Good choice and good price. The business went very well.

Awsome, I had some concerns regarding "No Name" products but it works with my D750 along with the 70-200mm lens just fine. Fast and accurate metering. For this price unbeatable......I decided to go for it instead for the more expensive Nikon SB910 ( $500 (

Great Product, Works without flash. I have become fan of Godox.

Love that it connects to my Godox Radio transmitter with no fuss.

I've scoffed at these relatively inexpensive kinds of speedlights for years. But when I saw that this model had built-in wireless TTL control, I decided to give them a try, and was pleasantly surprised. They are just about identical to the SB-900 in terms of physical size and power, but with the added convenience of full control (manual or TTL) of remote flashes with no additional triggering devices needed. The radio control does indeed work exactly as advertised. TTL exposure accuracy is identical to the SB-900 as well. Minor complaints: • On one of the four that I ordered, the locking pin would not engage with the camera's hotshoe (so, although I could tighten it down and it would hold pretty well, it could still slide off the hotshoe). The other 3 were fine, and the replacement was fine as well. • The UI could use a little polishing. For instance, you have to push a button to cycle through the various modes (on-camea, optical master, optical slave, radio master, radio slave). I know for a fact that I am never going to use the optical mode, and I wish there was a C.Fn setting to disable it from even showing up (as it's more "pages" I have to cycle through). Also, as soon as you start cycling through these modes, the zoom setting goes to M, but does not go back to A when set back to an on-camera single or master mode as you would expect. • If a setting is changed and then the flash is switched off within several seconds, those settings are not saved and it reverts to the previous settings when switched back on. However, if you wait about 10 seconds before switching it off, the new settings ARE saved. • The focus assist beam is not as useful as Nikon's. A pattern of short diagonal line segments is projected onto the subject, and in some cases the selected focus point will not coincide with one of these marks (as opposed to Nikon's beam, which is more "solid"). Using the D750's "group" AF setting (a moveable cluster of 4 focus points instead of just 1) helps. These focus assist marks are also more "noticeable" than Nikon's, so I'll likely try to not use this feature as much (though sometimes it's unavoidable). That said, for $120 it's a no-brainer. Nikon and Canon have gotten more and more carried away in recent years in terms of speedlight pricing. And Nikon's latest flash, which finally includes radio, is crippled to the point of being unusable for most photographers. The TT685N fills this void nicely, and I'm happy with the purchase. One other nice feature is that the radio feature of this flash also works with triggering the new AD360II, a very nice Qflash-like unit.
