I have got YN 622C a couple days ago.
I had no time for deep tests, but it seems that all is working perfectly. They are little bit bigger, than I thought. But it doesn't matter.
BUT I was really impressed, that YN 622C is working with my studio strobes too - and what is more - now I can shoot with my studio strobes up to 1/8000s ! That was something really unexpected for me.
So I am thinking to buy two more of YN 622C to use it as a main receiver/transmitter for my strobes. The old ones gave me 1/160s for my Canon 5D3. This one can help me with really quick movement, like jumping people in my studio, etc.
So - however I did not test them hardly yet - they seems just perfect for me. And the price is really nice.
Where did you buy yours? Would you recommend them in terms of shipping time, shipping price, and duties? Thanks!
I have bought them via ebay store - directly from the manufactuer. Web link: http://www.ebay.com/itm/Yongnuo-YN-622C-Wireless-TTL-Flash-Trigger-Canon-7D-5DII-5DIII-1DIV-1DIII-5D-/150878352686?pt=AU_Cameras_Photographic_Accessories&hash=item23210cf52e
At ebay, there are many sellers, where to buy. But this one "hkyongnuophotoequipment" (crazy name
) is official ebay seller just from Yongnuo. So, I bought it there because I was sure that I will get the latest version of YN 622C with support for 5D mk III (as I was reading at Internet, some of others sellers may have the older version without the latest firmware of 5D3 support ).
I am from Europe - The Czech republic - the package came from Hong Kong in 7 working days! It was really quick. Marked as a gift, so there were no more taxes.
