Thanks. Are those 100% crops? Are you saying that there are optimal slower shutter speeds that are better than faster speeds in some cases? I'm trying to optimize IQ as much as possible and shoot at f/8 to limit diffraction effects. ISO 400 seems to be very good, but there is some noise at higher ISOs so high shutter speeds are often undesirable.
I'm not so thrilled having the L bracket hanging on the Metabones when not needed, but the L bracket on the body seems unbalanced with the weight of shorter lenses, such as the 24 TSE II. I have a 2 series tripod and a Markins Q20i, so I'm familiar with such a setup. The 3 series legs with RSS 75mm leveling base and BH-55 is stronger than that, so the tripod is not the issue. I can do further testing next weekend. I do a lot of panning/stitching, so a few blurry images can be disastrous.
