I have recently upgraded to 8x10. After having tried four cameras, it seems that I will stick to a Calumet C1, which seems to be able to gladly withstand the ha rsh conditions of my outdoor shooting. However, although I am not a person who u sually complains about the weight of my equipment, I have to admit, sadly enough , that the C1 with the rest of the gear is really too heavy for joyfull backpack ing in the Swiss Alps or similar locations, where the slopes to swallow in one d ay are higher than several Empire State Buildings one on the top of another. In despair, I am thinking about consulting a machinist and drilling (reasonably) la rge and (reasonably) spaced holes all over these over-sized metallic parts. Did anyone make a similar experience or heard about it?
