Quote:Always wonder about statements like "until diffraction kicks in at f/11" - clearly, the center is diffraction-limited by f/5.6. This applies to many reviews...Indeed, it should be more like "until diffraction really starts to limit sharpness". And the sharpening in the PZ MTF workflow does mask the effect (the amount) a bit.
Lenstip shows diffraction softening a bit more clearly because of that:
