Lens for Laser Grid Measurements

I need to measure a laser generated grid 0.25mm width (4lp/mm) at 5 meters w/ 75% Contrast. Does anyone think that I would not be able to resolve that with a canon 135mm f/2.0 L, or the 200mm f/ 2.8L II lens at f/2.8? The MTF for both at 10LP/mm, 1.0 /1.5meters is 90% across the full field.
