Okay I'm trying to buy a ring flash and it is very confusing. My setup is a 1Ds body and I have the 430ex mk2. First up is the Ray Flash. http://www.expoimaging.com/...&keywords=Ray_Flash:_The_Ring_Flash_Adapter Now it says on the website the Ring Flash doesn't interefere with the TTL functions, but the device clearly blocks the AF sensor so this bit I don't understand. Does anybody use this? Then there is also this ring flash: http://www.ringflash.cz/en_eshop.php. Anybody use this, I've heard about it and while it is really cheap, I can't seem to find the option to buy it. This is a UK website offering their ring flash http://www.simplyringflash.com/buyringflash.php So far these are all for the 580ex flash head which I don't own, I don't fancy buying this flash head unless I REALLY have to. But this is part of my decision making process. Alternatively, there are these 2 adapters for my 430exmk2: http://www.linkdelight.com/...Flash-Accessories/View-all-products/Page-2.html and http://www.ringflash-adapter.com/...e.tpl&product_id=19&category_id=1 Has anybody used these or heard of the last one because it seems like the best one but their forum is full of adverts which I don't understand the reason for existing. It gives the impression it is a fake website, but of all things to fake, I can only guess as to why? I'm questioning whether a cheaper ring flash is going to do the job (weddings & fashion) and they all seem to block the flash head's AF sensor. Help is mighty appreciated thanks.
