Hi Chris,
I have used Baader Solar Film (5.0) on my telescopes and binoculars. Attached are some pictures showing my kit and the Sun in white light taken on Monday 7th May 2012. From a visual point of view, the results are excellent.
The image of the Sun is taken using a-focal photography and a Panasonic DMC-FT1 Digital happy snapper clamped to the eyepiece. The good news is that the view through the eyepiece is sharp as a tack. The bad news, for me at least, is that it isn't easy to replicate this level of detail in my images.
With your high spec photographic gear you should have no trouble at all.
I rate this product.
