Possibly a loss in sympathy, if your purpose is scanning.

As focal length increases, the high optical quality of filters becomes increasingly important, where image quality may be degraded by inferior glass or gels. I doubt that would be much of a factor with clean B&W filters. TMAX films would not be my choice for comparisons of sharpness. I hope you were at least comparing filter use using only TMAX examples. You might find more conclusive results with a high acutance developer like Rodinal or Pyro, on straight grain films. Lastly, your purpose for using moderately strong orange filtration on panchromatic films should be specific and rare, unless you are using artistic license with realistic tonalities. That, will otherwise degrade your images in far greater ways than simply putting more glass between the composition and the film.
