Derby, I had an early 67 and would not agree that it required any special treatment. It was a real brick. I never had a problem with my very used 67. You could probably pound nails and break rocks with one. It would be a great camera to have in a hostile crowd. With a long lens it would make a war hammer fit for Thor.
The shuttered len is a great option because the focal plane shutter shakes the camera without a heavy tripod. The shuttered lens was to get higher flash synch for weddings, etc. I never used the 90mm but if it is as good as the 55mm and 105mm it is superb. You might need the double cable release they offered. It opens the fp shutter in B just before the lens shutter fires. Wait 'till you lay a 6X7 Velvia chrome on the light box! Bill Lawlor
