Timmy, Thanks for the reply. I will go ahead with the YN-460 flash then.
Popo > Hi and yes it is tough to read the manual. Have you tried getting your hands on a YN flash manual. For godssake They are a china make. Youd be lucky if you found a small xeroxed pamphlet inside giving some vague instructions and nothing more. And i havent bought it yet to have even that.
So before you condemn my post, please do some research or at least see what we are talking about. Theres no use talking about your YN-462 when we are talking about a YN-460 II, they are both different peices of hardware.
Plus the questions i asked about the banding and how it can be overcome or workarounds etc are not questions you get from a manual. I read the maximum i could, have skimmed the whole of flickr to see results of the YN-460 and analyzed the exif data of hundreds of pics to see what shutter speeds were used etc. Ive done my home work to that extent and only then have asked this question along with some other ones on high shutter speed. If we could all solve problems/questions by just reading the manual we wouldnt have this forum would we ?

.
And where in the specs of a YN-460 II (i mean specs given in china's very own mixed up english on ebay, because you cant find specs elsewhere as i dont know if YN even has a website) can you find it says its NOT capable of HSS ? Again YOUR 462 doesnt figure in the question here so dont use that as a comparision. Your lucky you even got a manaul.

PS : Your idea of masking off the contacts....do you think that will eliminate the banding you'd get when you shoot at higher than the cam body's sync speed ? Have you tried that ?
