This was loosely referenced in another thread, but not expanded upon at all. Is it true that a lens with a smaller maximum aperture [f9] will contribute to focu s error by providing a larger on glass depth of focus, as compared to a lens w ith a wider max. aperture [f5.6]? I know Im probably not using the correct term inology, so another way to phrase the question would be; do lenses with a wider max. aperture provide the ability for finer critical focus?
For further clarification, I would be interested in the non-low-light aspect, th at obviously favors the bigger glass, but how about side by side in good light?
Thanks.
