Better Beamer

Arrived this afternoon from NAturescape. Very quick and painless. Any quick tips, important do it or lose it instructions for setup and use? :)
It suggests 'for best results set your flash head at 50mm when using this lens(fresnel)'. I intend using it with my 80-400VR and my 80-200AF-D any set up/ tuning advice? Would greatly appreciate any advice. It seems to clearly state that turn it to the sun and you become fried chicken! :shock:
cheers

have you seen this thread where I did some tests??

basically they aint kidding about burning your flash. or your lenshood either if you get the sun the other way. I would recommend not walking around with the fresnel lens fitted.

I think it is worth knowing where it is firing and you may have to add velcro etc to get the beam correct.

I set up a test with my 400 mm lens set at 80mm where I could see a bright spot centre of the image and adjust the shims/ beamer position on the flash til I got it centred.
you could also use the modellng flash function on your flash and use the mk1 eyeball to decide alignment.
max range is achieved with the flash set @ 28mm but you would need to assure that it was centred correctly to do that. the 50mm recommendation allows for some misalignment. test it and see.
