I'm not sure how companies rate their lenses for sensor pitch, but it could be based on diffraction-limited performance. If so, this would imply an aperture of ~f7.Lou Jost wrote:Looking at their other spec sheets, the resolution is always 120 lp/mm regardless of lens or magnification. That means it must be the resolution on sensor, otherwise it should be roughly proportional to magnification.
But I am concerned that the spec sheet says that the resolution is appropriate for a 4.5 micron sensor. The Oly sensor is 3.3 microns.
Edited to remove resolution calcs which I think were wrong...
