I hope this is not a silly question.

I bought a Dallmeyer 8” f2.9 Pentac in a Betax #5 on a Sinar board. The lens weigh 3.4 pounds. After the CLA I shot a few sheets with an Ebony SLW 8x10 a light weight camera to test the lens and the coverage. It covers a full body environmental head to toe shot with reasonable sharpness in the center at f5.6 The lens weigh half as much as the camera and when I mounted it I feared something might give. I only used a bit of rise and fall.

Am I taking a risk using such a heavy lens on a light weight camera?
