Do I need to buy a master flash or some other device to trigger and use TTL function off-camera (Canon T3i)?

I shoot with a Nikon that has options to trigger a remote flash. Not familiar with Canon T3i.

If you are using a third party external speedlight, it will not fire in live view mode. I am not sure if it works with ttl speedlights but it definately doesnt work with manual speedlights.

You need a transmitter on the camera and a receiver attached to the flash. To fire the flash with a sync cable you need a cable that has a hotshoe on the flash end and something that attaches to your camera's sync system. I don't know how many TTL features are retained when you go off camera.

You can use it but only in Manual Mode! TTL Will not work, any kind of flash, canon, nikon or the new hot shoe sony's, but i recomend to you the Yongnuo

If you want to trigger it with TTL, yes. There are pocket wizards that do the same thing and they are much more expensive! You can trigger with manual mode on these as well.

NO. This flash is full manual, no CLS, TTL, or High-Speed Sync. But it is built like a brick. In a good way. There are (all of a sudden) a bunch of third-party manufacturers building products that have Nikon or Canon's proprietary TTL technologies built in. I don't know about other manufacturers, but I know this: everyone is using the Yongnuo brand flashes and digital controllers. They fit right in with your existing Nikon gear, and while they aren't built as well as the LumoPro, they are around $100/ea, so if it breaks, get another one. Or three. At these prices, you really can be like Joe McNally and have a bucket of speed lights. Here is the flash on Amazon: http://www.amazon.com/Yongnuo-YN565EXN-USA-i-TTL-Speedlite-Warranty/dp/B00I44F59A/ref=sr_1_2?ie=UTF8&qid=1428023722&sr=8-2&keywords=yongnuo+nikon+ttl Make sure you buy the latest version. When you view the page, you will see the wireless triggers in the accessories pane. Hope this helps.

A wifi trigger is a pretty dumb device, as long as the flash contacts in the hotshoe fit, it will trigger. No TTL, however, all manual. If you have a proprietary shoe like the old Minolta/early Sony, that flash will need an adapter, but that's the only exception.

I have a D300s, but these are manual syncs. There is no reason why they should not work. You will not have access to TTL though.

I don't know about that but this flash is fully manual. It will not monitor anything thru your camera and mine stopped working the 2nd time I turned it on. I would not recommend it. If you want a TTL ring flash that is fully automatic you will have to go for the Canon ring flash, about $500.

No TTL, that is correct. But I put an Altura flash (about $40) on this shoe, put that combination on my 5N, and it works beautifully in Manual on-camera function. I have not tried it yet as a slave unit on a tripod.

Yes, but there is no TTL. Either use the built-in camera meter or a light meter, like a Sekonic. Or, as the ultimate fallback plan, just adjust the power output until the exposure is correct.

Yes it does! You will have to adjust the output power manually. Once you set your desired just keep shooting. Does not work in TTL mode. There is no settings you need to adjust in either camera but makes sure your shutter speed is set to no more than 1/160sec. Or you will get a dark shadow in the bottom of the image. Good luck!

I believe you don't. This flash is E-TTL and compact camera doesn't use it (it requires a SLR camera). I use it in a G9 and G12 in full manual mode.

Why wouldn't, if the flash syncs with your hot shoe of your Canon T3i ? Your only extending the technology that exists to any flash that possess TTL.

You may need a wireless remote flash trigger, liken the NEEWER PT-16GY 16 Channels Wireless Remote Flash Speedlite Trigger for Canon SpeedLite, see it on Amazon for just $15.00, they also have very illustrative pictires.

As this is an automatic flash, it should work automatically when mounted properly onto your Canon Rebel T3i. Keep in mind, this is not an intelligent TTL dedicated flash and will not adjust to your environmental lighting conditions.

Yes...This little hot shoe has a metal contact at both its bottom and top that allows any brand flashes that has a contact to this hot shoe fire off when camera shut release button is pressed.However, for using your old flash with this hot shoe, your old flash must have a manual output settings. That's being said, you can NOT use the camera's TTL flash control; you have to use manual control to tell it how much light it should be firing off. Good luck, John
