That is to be expected if you have bright sun or even bright cloud and if you use a film faster than FP4+ and ant to use a lens wide open you may find yourself struggling. I have a light weight tripod, not the best for stability and on the odd occasion when I need to get the image as sharp as possible it can be useful.
In fact many people who are disappointed by the performance of a particular lens when they use a tripod it shows exactly what the lens is capable of producing. Although this particular tripod is a lightweight the central column has a hook on the bottom and I have loop made from a thick zip-tie so I can put in in the hook and stand on the zip tie the tripod is as steady as my Manfrotto 55 which must be about 6 times a heavy or possibly more.
What I am trying to say is, with a slow film in your camera and a tripod you can use as slow a film as you wish
