I have 4x5, 5x7, and 8x10 cameras and the 8x10 is a big jump up in terms of bulk and weight. If you can afford a lightweight 8x10 and small lenses with good coverage, and are willing to lug fewer holders, then 8x10 won't be too bad. I have a Deardorff and aside from any accessories--it's not a light camera. Add a couple of plasmats and half a dozen holders, dark cloth, tripod, accessories--and it starts to be a real load.
