I'm looking to buy an intervalometer for my kit. I have a canon 7D and a T3i, which use incompatible connectors (why, Canon, why?) which means if I buy the Canon units, I need to buy one for each body (oh. that's why, Canon. sigh).
I'm investigating third party intervalometers that have cables where I can buy a single unit to drive both bodies when I want to; Right now, the one that seems to meet my needs best is the Promote Control ( http://www.promotesystems.com/products/Promote-Control.html ).
I'm looking for recommendations or alternatives to consider in my research. Is this unit as good as it seems? Are there others that will work for both HDR bracketing and timelapse work and be compatible with both bodies? Any other things to keep in mind or units you might recommend?
