I have now finished doing my blue Peter bit.
I had a go at trying to refine what Lello has done. I made the center hole much bigger to allow the lens to go in a lot further, this allowed the af to work without having to constantly re-align the diffuser and plus I don't need the lens hood.. The first two photo are with the 50mm lens and a plant taken with the finished result. The second two were with my 300mm lens set at max 300mm and I stood 6 feet away.. The last photo is the result of this, its soft but I am quite pleased.
Thanks Don and Lello I now have my very own ring flash.
I will be trying the setup with the ext tubes to give me macro and see how that goes.
