Tahoe sounds great, but unfortunately I'm not going to be able to make it. I'll be there the previous weekend for spring break with the family. Thanks for the advice on lenses. The SK 60xl didn't seem to fare well in the DT library tests, unfortunately. My lens selection has been pretty limited with Canon. I use the 24 shift 70% of the time. But in my 4x5 lens bag is everything: SK72xl, Nikon 90 4.5, Rod 115, Rod 135s, SK150xl(8x10), Rod 180s, Rod 210, 240 app-ronar, 300mm (apo-ronar?), Nikon 450mm process lens, and the Nikon convertible 1200, 800, 600. I didn't bring anything bigger than the 240 to any job unless I knew there would or might be big distances to cover or small details to capture.
The 115 and 90 were used for most of the shots, and I rarely went above the 150. We're talking Architecture.
With the 1.3 crop for the IQ250 I was looking at 23HR, 32HR, 40HR, 50HR. Triple those focal length to get a ~4x5 equivalent = 69, 96, 120, 150. That seems like it would carry me, though I'd love to get the 70HR and larger in the future. Had I gone to 60mpx ccd route, I wouldn't need the 23, which is a large chunk of change. Believe me I weighed the options.
Hope to catch another workshop, but I'm a working photographer and a father to two little kids, and I've got to step up the marketing to pay for some new kit. Time is scarce.
