I want to get pictures of the total solar eclipse in the US on Aug 21, and what I'm struggling the most with is finding solid information on what to use on the front of my lens. Obviously I need to filter the light, but I've seen references to a "solar filter", which presumably is specifically for viewing the sun; but I'm having a hard time finding "solar filters" for a camera lens (specifically 95mm diameter). There seems to be some accessories and whole sheets of solar film intended for a telescope, but I'm not sure how I'd mount it on my lens. The other option seems to be ND filters, but it's unclear the number of stops in reduction of light I would need, and some seemed to suggest that a ND filter wouldn't filter out harmful non-visible light (IR and UV). How important is that for the camera internals vs my own eyes (if I were to use the viewfinder). Finally, if I'm looking and photographing the sun using Live View on the camera, I presume that could be stressful for the sensor; if nothing else make it very warm and introduce a lot of noise even at ISO100. Is this a valid concern?
