First of all I'd like to disagree with what's been said about focal lengths. I have found myself using wider and wider lenses as I go up in size. I prefer 100mm of TF (TinyFormat), 75mm in MF, 135mm in 4x5", 150mm in 5x7". So far I have only a 165mm for 8x10"(really 18x24cm), and I fear I could get used to it. I also wonder about an antique 135mm WA lens I came across...

So if you like long lenses in TF, it doesn't necessarily follow that you'll want a 300mm lens for 4x5".

Front tilt and rise are the most important movements. Rear tilt is very nice. Rear swing would be my next choise, even before front swing. But that's because my landscapes are almost vertical...
