If I got a penny for each question I get about equipment I'd be a rich man. I use both digital capture and film capture. My general preference is Large Format with Fuji Velvia film. Fuji Velvia is a high contrast, low grain, high saturation film that renders landscape images beautifully. My lens selection for 35mm Digital are influenced from my background with large format cameras. The tilt/shifting features of Canon TSE lenses allow me to control perspective and distortion to an extent that are otherwise impossible with non tilt/shifting lenses. I have been through several cameras and lenses throughout the years, currently I have:
Camera Body: Chamonix 045n-1
Lenses: Rodenstock 65mm Grandagon-N f4.5, Schneider Super Angulon 90mm f8, Rodenstock Sironar-N 180mm f5.6, Schneider Symmar-S 150mm f5.6, Fuji films (Velvia 100/50, Provia 100f, Astia 100f), Pentax Spot Meter, Scanning: Colorgetter Plus and Screen DTS-30ai Drum Scanner
Camera Body: Canon 5D MKII
Lenses: Canon 17-40mm f4.0 L, Canon 24mm f3.5 L TSE (Tilt/Shift), Canon 45mm f2.8 TSE (Tilt/Shift) Canon 90mm f2.8 TSE (Tilt/Shift), Canon 300mm f4 & Canon 1.4 TC, Canon 70-200mm f4 L
Filters: Hitech 2,3,4 Stop Graduated Neutral Density Filters (Soft and Hard)
Nikon Circular Polarizer, BW 10 Stop Neutral Density Filter
I tend to carry both equipment in the field... I generally carry the Canon 5D on a LowePro chest pouch and 3-4 lenses with the Large Format on an Internal Frame backpack. Add bear canister, 2-4 days supply of food, tent, sleeping bag, etc., and you can begin to get an idea of weight that I carry...surprisingly it's less than 40lbs - check out www.backpackinglight.com for tips in this endeavour.
