Re: Resolution at long focal length settings

Ian:

I should have noted that my examples (3mm=sharp, 1mm=soft) apply to long and short focal length lenses that have a normal field of view, equivalent to a 50mm lens for a FF camera. If you narrow the field of view then you will also need to narrow the angular resolution to maintain the same image sharpness. That is why telescopes need large apertures.
