Operation is intuitive with a rear LCD panel that shows settings. Also, the flash is equipped with a Wireless Control Port for attaching an optional remote control set and it has a 3.5mm sync port for basic wired connectivity. It runs on four AA batteries, which help provide a recycle time of 0.1-2.6 seconds.

It can also work with an optional X series transmitter for creating more elaborate setups.

    Godox TT685O reviews

    TT685O Thinklite TTL Flash for Olympus/Panasonic Cameras is rated 4.0 out of 5 by 6.
    Rated 3 out of 5 by from Reasonable price for full function flash I bought for use with my Lumix DMC FZ300.� It does the job for this non-professional photographer. Build and design is a lot like my Nikon SB900 and SB800 flashes. However, there are a few drawbacks to the unit: 1) The shoe attachment plate is hard to properly position on camera; 2) The locking device for the attachment is a screw down rather than a quick lever as with most other flashes; 3) The function buttons are poorly labeled; and most importantly, 4) The instructions are poorly written, hard to follow, and downright unintelligible. I am not sorry that I bought the flash as it will be used only occasionally. If I were to have it as my primary flash for my Nikons it would have been a bad choice.

    Rated 5 out of 5 by from All I wanted and more I am a retired news photographer trying to keep a hand in the profession I still love. I keep things simple when I can. My new GODOX TT685 is doing all I ask of it, as a primary camera-mounted flash in TTL mode. I purchased this flash on the basis of price and capability - the unit can be used as a master or remote slave with electronic capabilities far beyond my needs at this stage of my career. The unit is well built and more than fulfills my expectations.

    Rated 3 out of 5 by from Good bargain with you can accept its limitations I bought the Godox TT685o for use with my Olympus E-M1 Mark II camera.� I had tried using several models of Olympus optically triggered remote flashes with sporadic success.� Too often the remote flash would not see the light from the triggering flash and would not fire.� So I decided to try the Godox radio triggered flash instead. ���� I have now used the Godox flash for several months in a variety of situations and can now comment on what I think are its strengths and weaknesses.� First, the strengths.� The Godox unit appears to be of sufficiently rugged construction for normal use.� It recycles reasonably quickly and gets a good number of flashes per charge.� The LCD panel is easy to read and the buttons and dial easy to use.� The flash head tilts and swivels to various positions without the need to press a release button but takes considerable effort to do so yet it always stays in place.� The flash's radio trigger works well with the the Godox X1To transmitter mounted to the camera (with one exception which will be noted) and was able to receive a signal at a distance of about 80 yards.� ��� Now to the weaknesses.� My main objection to the Godox TT685o is that it does not cover the field of view and rather severely vignettes the corners of the photo, especially for wide angle shots.� I did tests with the flash on the camera hot shoe and photographed a blank white wall at various lens focal lengths with the flash on auto zoom.� With the lens at a particular focal length I would note the flash zoom setting on the flash LCD.� Here are� samplings of various lens focal lengths and the accompanying flash zoom settings: lens @ 12mm, flash reading 14mm; lens @ 14mm, flash reading 17mm; lens @18mm, flash reading 25mm; lens @25mm, flash reading 35mm; lens @ 35mm, flash reading 42mm.� One will note that in every case the flash head is zoomed to longer focal lengths than the actual lens focal length which would explain the vignetting effect.� The Godox manual states that the flash auto zoom covers focal lengths from 10mm to 100mm.� I have attached two photos, one at 12mm and the other at 100mm of focal length.� As one can see the 12m shot shows severe vignetting and the 100mm shot very little.� My intermediate shots show the vignetting effect to be acceptable to me at about 35mm. ���� I wrote an email to Godox to ask about the vignetting issue and never received a reply.� I decided I might have have a uniquely flawed unit and returned it to B&H and ordered a replacement.� The replacement unit had the identical problem.� So I think either Godox has a design flaw or a manufacturing calibration flaw with this model.� Incidentally, I also have a Godox TT350o flash and it does not have a vignetting problem nor do my Olympus flashes. ���� So what can you do to work around the vignetting problem?� You can use the manual zoom feature with the flash instead of the auto zoom.� This option may work if you don't need to work quickly.� Secondly, you can use the flash with a softbox or reflective umbrella to spread your light.� Or, thirdly, you may bounce the light off of a low white ceiling to spread the light for wide angle shots. ���� My other complaints about the Godox TT685o are relatively minor.� The instruction manual is only fair and if you are not already familiar with setting off-camera remote flashes it may prove difficult to understand.� The flash case could use a belt loop to make it easier to carry with you.� If the flash refuses to fire, check the batteries which may be low.� The manual says the battery icon will blink when the power is low but I never saw it blinking when the flash refused to fire and I finally changed the batteries.� Lastly, the Godox TT685o will not fire if it is too close to the Godox X1To transmitter.� The flash seem to need to be at least 6 to 8 inches away from the trigger to operate.� Strange but true.� This was only a problem when I wanted to take macro photos and hold the flash right next to the camera lens to illuminate the subject.� In this case one can use a cord between the camera hot shoe and flash and dispense with the radio triggering. ���� I have down graded the Godox flash one star rating for the vignetting issue and another star for the Godox company's lack of response to my inquiry. ��� So there you have my review.� The Godox TT685o is certainly a bargain price compared to other radio triggered flashes.� If you decide to get a unit, check it out and decide if you can live with the vignetting issue.� If you can't,� B&H will gladly issue a refund.� Who knows, maybe by now Godox has fixed the vignetting issue.

    Rated 5 out of 5 by from It works. This was "a pig in a poke" since the only flashes I've ever used were Canon.� I wanted one for my E-M1 Mk II, but didn't feel like paying the price for an Olympus one.� I've only tested with it so far, but it seems to be doing the job nicely.

    Rated 3 out of 5 by from Excellent Unit But With Caveats Pros: Well made. Cons: No external (Panasonic) connection without X1 trigger. No firmware support for Mac users. Instruction manual is sketchy. No US support (phone, email, chat). Email for Chinese tech support bounces back.

    Rated 5 out of 5 by from I bought three Works good with my Panasonic cameras. I like the fact that you can use them as master or slave with the wireless radio transmitters. But I went ahead and bought the Godox X-Pro flash trigger to control the power settings on all of my Godox flashes. No complaints. TTL works.
