Originally posted by JeffJS The K5 does not have a separate bracketing button but something like the RAW button can be set for that purpose. I don't believe the K7 does either. They are both in the Drive mode menu. That has been one of the (minor) complaints about the newer layout of the flagships.
My old K100 had the port for an external wired release, and the menu item had the IR, setup so that you could not do the IR and Bracketing, but it was fully available with the wired option.
On my K20, the dedicated bracketing button is REALLY nice - I use it a lot.
I see on the K5 that they have moved the wired port to the right side of the body, so that it no longer interferes with a L Bracket when its mounted.
Why the K2K, Kx and Kr went to the IR remote only but left the bracketing in is just one of the more stupid things I have run across. I understand that they want to differentiate the models, but you still need to make them useful.
