For the last 30+ years I photographed primarily with an Arca-Swiss 4×5 view camera. My version was the F Field Clasic with Micro-Orbix. Many of the images in my gallery were composed with this camera using various lenses. The most knowledgable person for Arca-Swiss in the United States is Rod Klukas, formerly of Photomart in Phoenix and now the US representative. For additional Arca-Swill resources see Tom Westbrook , Precision Camera Works .
I have moved on to a Canon EOS 5D MKII system. While not providing the same image size as the Arca-Swiss, the Canon DSLR offers many advantages. Foremost is the very quick turn-around from image creation to processed image. With the Arca-Swiss and shooting with Velvia film, I would wait a minimum of one to two weeks for my processed images to return. Then of course I needed to decide if I would pay for a high quality drum scan or a lower quality flat-bed scan on my Epson V750. Now I just import into my raw processor of choice, Lightroom 3.4.1, and then finish the image in Photoshop CS5.
A second advantage of working with my new DSLR is the ability to use the Live View function with my Hoodman Loupe to essentially function as if I had a dark cloth over my head and then zoom in to the image up to ten times. This suits me quite well as I am used to working at the much slower pace of a 4×5 view camera. This method is very useful when using my TS-E 24 mm. A third advantage is great simplification in determing proper exposure. Sure I can still use my Pentax 1degree spot meter but using the camera histogram and exposing to the right is much simpler.
