I bought this to use as a TTL flash with the Canon Rebel 2Ti I attached it to the hot shoe. The photos were either so bright they were washed out or they were blurry. I tried every setting, tried it with the display on, with the display off... I see others used it successfully so the error may be mine but I googled endlessly, experimented repeatedly and finally just ordered the Canon Speedlite. If someone reading this has used this flash successfully with the 2Ti I would love to know the trick.
