Unfortunately, if the lenses for your Sony DSLR are "DT" model lenses they really can't be used on the Maxxum. The "DT" series of lenses is designed for the cropped sensor of your DSLR and thus will cause vignetting on the Maxxum. Why? Because the image circle of the "DT" lens is too small to cover the 24mm x 36mm frame of the Maxxum. You can' of course, use any Maxxum lens on your DSLR with no problems. In fact, since you're only using the "sweet spot" of the lens you may get better results. If your lenses for your DSLR are not members of the "DT" family then they should perform just fine on your Maxxum film camera.
