It probably will work (though i can't be sure) in normal mode.
You can test (sort of) by firing the shutter while looking through the rear, and see what happens, in what sequence. The important bit is that you don't see the shutter and aperture close and then go open and shut again. The thingies in the lens need to be closed when the rear shutter doors open.
So if you only see the shutter open and close, with the aperture closed as far as it should be (test at 1 second with the aperture set to f/22), things may be o.k.
But it's hard to see what really happens while the rear doors are opening. If that opening happens while the shutter in the lens and aperture are still closing, you're in trouble...
