I tested my Minolta 9000 and 9xi at just those shutter speeds with a 400mm lens attached, and camera securely attached to a tripod with Tmax 100 film. Under an 8x loupe, I was unable to detect any evidence of blur with the negatives shot with the 9xi, but most defintely could with the older (and much louder) 9000. I have since traded in the 9xi in favour of the 9 (Minolta seems to love the number 9, don't they?), and haven't had a chance to repeat the test. The 9 happens to have a version of MLU (2 second delay with the mirror flipped up and aperture close down prior to exposure) and also uses the same shutter as the 9xi. My experience with the 9xi agrees with similar reports on the Minolta mailing list.
