[Digital BW] Re: Zone focusing

2009-07-22 by grangermacy

The ghosting problem is a great question.  Someone should check out the effect of different lens designs.  My guess is that IF lenses should have an advantage as the front element isn't getting closer in focusing.  But certainly the more recent Nikon macros that change focal length while focusing would be a very bad choice.
