    I take 360 degree HDR panoramas which require bracketing at 5x3 EV stops, the EM1 makes this easy by letting me bracket with a single shutter press. However, I'm looking for a mode that will adjust both shutter speed and aperture.

    Currently, what I do is set my camera in manual mode with a shutter of 1/125th, when I bracket, the camera adjusts the shutter speed to 1/8000, 1/1000, 1/125, 1/15 and 1/2. This gives me exactly the range I need without blowing out the shutter. So far so good.

    Now, the problem with this is that at 1/15th and especially 1/2, any movement becomes visible, this means if it's a windy day, trees and/or clouds will be moving and cause a lot of blur in the brightest exposures. This makes it difficult to capture panoramas on windy days.

    What I would like is a "smart bracket" mode that adjusts both aperture and shutter speed, for instance:
    F32 1/8000
    F11 1/8000
    F4 1/8000
    F4 1/1000
    F4 1/125

    I generally focus at infinity, and am shooting distance objects with a fisheye lens, so most of the scene is in focus at F4, and stopping down wouldn't significantly change the DOF.

    It seems like bracketing in aperture priority works essentially the same as M (only the shutter speed is adjusted). Bracketing in S mode adjusts the aperture, but the shutter speed remains fixed, and adjusting the aperture alone doesn't give enough exposure range, so the various exposures do not work.

    At this point I'm just going to assume that what I want to do can't be done, but I welcome any input.

    While I'm on the topic of stuff I'm pretty sure my EM1 can't do:

    It would be awesome if I could do a 7x3 EV bracket as well, and a bracket mode that would alter aperture, shutter speed, and ISO, for instance:

    F32 1/8000 ISO 200
    F11 1/8000 ISO 200
    F4 1/8000 ISO 200
    F4 1/1000 ISO 200
    F4 1/125 ISO 200
    F4 1/125 ISO 1600
    F4 1/15 ISO 1600

    What about P mode with a set ISO?

    Good suggestion! This is the only mode I hadn't tried. This looks like it might actually work. Now I just need to wait for daylight to try it out and see if it pushes my into an invalid shutter range.

    not sure if it'll work, but i think it's worth a try. You might need to make sure ISO is high enough, so that at the most bright exposure doesn't drop your shutter speed unfavourably. I don't have my camera to test atm.
