Question: Will this work on a Canon 5D mark iii?
Document: I like it, it works better than my Canon 580 EX. And it ETTL very well with my Canon ESO 5D Mark II with more power output too.
My 580EX II's swivel 180 degrees both ways. Either way, ETTL works great on both my Canon 5D Mark III and Rebel T2i. Decent product for the price. I would recommend it.
I have used this as an umbrella flash triggered remotely by an Impact PowerSync 16. It works. I have also used it as an optical slave if I'm triggering it with my other flash. The quality is very good and feels very solid. I have also used it on a Canon 1D Mark II and a 5D in damp conditions and it was very reliable. This is a great alternative to the 580/600 if you're on a budget.
Got this for my T3 and 5D mark 2 and yeah it works great, E-TTL works fine and the output is even stronger than the 580. Its not as strong as the 600EX but you may never need to use this flash at its full power. works as a good fill flash and just about what ever else, its built very sturdy, some reviews may say its not built good but yes it is, i've dropped it twice before and no dents or troubles.
If you like to save some money, you should buy this flash.. Is awesome, work the same way than the canon 580, is ETT-L means that you can be in long range and is perfect for you pocket
Everything seems to work, solid build. So far no complaints. I will say, the pilot charges WAY faster than my older Canon 420. Haven't had to wait once.
Yongnuo YN-565 EX TTL Flash Speedlite Canon. look and feel very solid and work fine. good flash for starter or for extra external flash.
I was so glad with flash ans photos results, but after 3 months of a not heave use the flash just stopped work. Next time I will buy a Canon one
I used this flash 15 times with my Canon 60D (indoors) and after about 15 shots, it died. I put in new batteries and it still wouldn't work. I am sending this back and buying a canon flash. Don't waste your money.
At first I wasn't too sure about it but after getting it and playing with it, I'm a happy camper. The plus is that the external battery packs that I have for my Canon flash units actually fit and work with this flash unit. Will probably get a couple more in the future.
Answer: All Canon DSLR cameras use the same flash type, so, yes.
