I love shooting large format as each negative can be processed separately. It slows me down too.
I shoot with a Sinar Norma and an Intrepid 4x5 and use only one lens at the moment. It is a Sironar-N 210mm f5.6. Check out my blog at bwfilmdiaries.wordpress.com. Oh yes, I'm also publishing a free monthly film photography magazine at ISSUU. Still looking for contributors.
