I think that exposure lock switches matrix to center-weighted at the time of making the calculation. That is, if the camera allows the two to be set at the same time the program would have to shift out of matrix or else there would be too many images that would be just unusable due to things like bright/dark areas that the matrix too account for but then were not in the final exposure. My F4 did this, if I recall correctly. Phil Forrest On Sat, 12 Mar 2011 19:33:09 -0600 (CST) grduprey at mchsi.com wrote: > Marty, > > Are you sure it works?
