from the specs, its a very nice flash. 2 years warranty, has all the bells and whistles. was ready to pull the trigger on 2 at new years time. but read a review that said it consistently underexposes by a stop and asked phottix and they denied it. 3 weeks ago they released a new firmware that fixed the accuracy. but im over them and looking for either an SB910 or a Sb700.
truthfully, all these 3rd party flashes are great, but I have to admit, from having yongnuo metz and nikon, the nikon flashes are just better. the accuracy is just better with them. far from perfect, but still, for the prosumer or semi pro and of course hobbyists, yongnuo, cactus, godox, phottix, oolong, cheetah, mieke are just great. for me, I decided for the TTL BL, the best flash on camera should be a nikon. for off camera, does not matter. they are all the same. love my cheapo YN560III for off camera manual fired fill flash. for $72 shipped its fast, powerful and has what I need. I just wish it had a wider zoom dissipation. I think the widest is 24mm. not too wide IMO.
I did a lot of research and for those looking for a 3rd party flash with the most bells and whistles out of any 3rd party flash, the phottix mitros is it. the best of them all. powerful fast, all the toys.
