the only lens i have that i know delivers the resolution to make it obvious that 4000dpi isn't enough is my FA 50 f2.8 macro. the next closest is my FA* 80-200 f2.8, but it's marginal as to whether it really has higher resolution or not. this is on Provia 100F. using Velvia, the macro has easily visible higher resolution. none of my other lenses push the envelope using Provia 100F, and that includes a couple of lenses with "tack sharp" reputations here, but they are all zooms. this is at reasonable shutter speeds (at least 1/60) on a tripod. i haven't tried any of the mid range primes or the Limiteds, but since several lens testing sites place them at about the same resolution as the my FA* 80-200, i would expect the same as it.
