A young tog I know has an issue with his kit which I cant help with so thought I would ask in here on his behalf.
He bought himself a NeewerTT520 speedlite and tried it on his "old 20D" afterwards the camera pop up flash would not "pop up". He also gets some other unconnected probs with this cam so decided its knackered and bought another 20D.
Once again after using the speedlite on the "new" 20D, the pop-up flash will not activate or "pop-up".
He does not get any error messages and the speedlite is supposedly compatible with his 20D's.
In my limited dealing with flash (on a nikon) I have suggested cleaning contacts etc but this has not helped.
He has also bought a 50D but is scared to put this speedlite on it (rightly so)
I'm guessing this speedlite has "fried something" on both cams ?
Anyone had dealings with Neewer spedlites?
TIA
