[filmscanners] Re: Better DOF than Nikon?

Hi Paul

          How many slides are you talking about?.   Tens, hundreds or a
thousand?.

          Another alternative would be to "copy" them using the old
camera-bellows-slide holder system.    Then scan the copies.

         This however would introduce another source of error/distortion/grain
etc of the image.     Unless of course you have enough slides and you seem to
be in the buying mood, you could use it as the excuse to buy a decent digital
camera so you could "digitize" the damaged slides in one step using the
bellows etc.

        I have not tried it, but imagine the DOF of a stopped down regular
50mm lens would be significantly better than of a film scanner.

        My $.02.

        Best,  Alex
