Yes. The Graflex Speed Graphic 4x5 I used at the Photo Staff when I was in high school had a typical Wollensak Raptor 135mm f/4.7 lens, about the EFoV equivalent of a 35 or 40 mm lens on a 35mm FF camera. One of the challenges was getting the focus and focus zone right because you had so little DoF to work with. With the lens wide open (to get enough shutter speed for basketball) and the focus set to 15' (a typical basketball shot distance at the basket), you had about three and a half feet of DoF total. In 35mm with the Nikon F, that would take a 35mm f/1 lens, wide open, at the same focus distance. I certainly didn't have any 35mm f/1 lenses in my bag in 1971… :-)
Interesting. Here are a couple of the shots that gave me pause, where the plane of focus seemed almost more geometrical then optical: http://i2.wp.com/roadsandkingdoms.com/uploads/2013/09/1200w_hor-talagante.jpg?w=2048&quality=75&strip=all http://i1.wp.com/roadsandkingdoms.com/uploads/2013/09/1200-mike-and-david.jpg?w=2048&quality=75&strip=all http://www.davidburnett.com/gallery.html?gallery=Big%20Camera#/15 http://www.davidburnett.com/gallery.html?gallery=Big%20Camera#/1 http://www.davidburnett.com/gallery.html?gallery=Big%20Camera#/14 http://www.davidburnett.com/gallery.html?gallery=Big%20Camera#/11 http://www.davidburnett.com/gallery.html?gallery=Big%20Camera#/12
So you can see the dynamics of format influence are very profound. Just sticking a lot of megapixels onto a tiny chip wafer does not net a large format camera view of the world. For my needs with a 35mm FF format camera, 24 MPixels are enough … More is occasionally nice, but mostly unnecessary. And no 35mm FF format camera supplants the Hasselblad 500 or SWC in terms of overall image dynamics … they're just too different.
In theory, with something like the Lytro you could recreate a lot of the feel in post processing. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
