Yup, quite small and sharply printed in the beg. You would sacrificing a fair amount of an already small 35mm neg to crop it out. Easy enough to alter your routine to enable it before loading and then disabling it after frirst frame advance, but then I have managed without such data for forty years or so. New toy, had to try it.
I'll scan one and post it tomorrow if you are interested in seeing how far it intrudes.
