Originally posted by Malaya I am now starting to clear my doubt for this flash.
If it makes you feel more confident about the brand, I suspect that Yongnuo probably makes more flashes than anyone else in the world. They are everywhere.
Their whole
flash system - flashes, triggers etc - is also quite extensive, and ever-expanding, which gives you lots of options.
Hopefully one day they will directly support Pentax HSS, and offer a radio trigger that works with P-TTL too. [Hopefully one day they will also improve their web-site].
