Weather permitting, I plan to visit the totality spot (in Missouri; ~13 hours driving for me from Ontario) this August. Will bring my family.
I plan to bring some minimum gear, hoping that I'll mostly be enjoying the experience, not getting busy with lens changes and such. So I'll probably only bring a regular tripod, Canon 50D with one lens (70-200 f4L), and an HD camcorder for my wife.
I've never witnessed a total eclipse, so have no experience photographing it. Just googling found this link:
How to Photograph a Solar Eclipse
The important point there is that one cannot take a single shot of the corona during the totality, because of its huge dynamic range. Looking at their table, it looks like my optimal setup will be 70mm @ f/4 (ISO 200), with exposures from 1/2000s to 1/2s to expose the corona parts from 0.1 to 8 of the solar radii away from the disk. I will try to setup a multiple exposure bracketing sequence using Magic Lantern, with the idea to do HDR in post processing.
I am not interested in the partial eclipse phase, so will not bother with ND filters.
Who else is going? What gear are you bringing? Any tips or tricks from seasoned eclipse photographers?
