If you want to capture those streaming corona then up to 15 radii of the sun would give a calculation for the ideal focal length for that type of shot.
Peter Ward had a nice shot of this from the Libya eclipse. I wonder what focal length lens he used there.

I used a William Optics 80mm APO and Pentax *istD. WO have a new GT81 which has even better optics...but make sure you get a modded version as early production runs had woeful internal tube reflections which killed contrast.
As I posted elsewhere, I'll be running a Canon 5dMkIII and 500mm L series F4 on a Starlapse this year....which should deliver way less noise, and much better resolution than the non-tracking system I used in 2006.
15 Solar radii would be tough...Miloslav Druckmuller uses unique software
(he wrote it) with highly calibrated flats etc. to get simply amazing dynamic range that I have yet to see replicated.
