Are there reasons why the performance of long lenses is generally worse than that of shorter lenses ?
I base this question on the lens tests I've seen on the internet, like those of Perez and Thalmann: we might not be shocked to see 60+ lpmm for an 80mm or even 150mm lens, but we never see that for a 300mm or longer lens.
One would think that greater precision would be less important when dealing with comparatively longer distances.
