This optic shows itself capable of producing good centre resolution at most apertures and focal lengths. At 24mm the centre resolution is already very good at maximum aperture and the quality towards the edges is approaching good levels too. Stopping the lens down improves sharpness across the frame until f/11, where the resolution is very good across the frame.
Zooming to 50mm causes a slight drop in sharpness at the centre but at maximum aperture the sharpness is still good here. Peak quality across the frame is found between f/8 and f/11 where the lens produces very good sharpness across the frame.
As with all high zoom lenses the quality falls off, but the performance is still more than acceptable At 120mm the resolution in the centre at maximum aperture is just scraping good and the quality towards the edges is acceptable. Stopping down to f/5.6 causes a huge jump in the resolution at the centre, but the quality towards the edges is only improved a little. Peak quality across the frame is found between f/8 and f/11 where the sharpness is very good across the frame
