My own way of doing it is to set the aperture blades "just" fully opened at max aperture, then stop down to inspect for evenness. It may not be 100% precise (no such thing btw according to the service manual), but wouldn't be too far off. This is especially true consider there is quite a variation when the lenses are set to 'A'. So if the loose tolerance DA/FAJ lenses were considered fine, you should have no problem to employ this method in practice. But now lenses can be tested on D/DS directly, re-adjust should be a breeze. Alan Chan http://www.pbase.com/wlachan __________________________________ Do you Yahoo!? Yahoo!
