Image quality

WHILE the resolution graphs of each lens look very similar, there are a few models that really stand out. Most notable are the Zeiss Planar T* 50mm f/1.4 and Zeiss Makro-Planar T* 50mm f/2. At 1 stop down from the minimum aperture, both these lenses perform exceptionally well, with the f/1.4 resolving the most detail of any lens in the test. While the Zeiss f/1.4 is extremely sharp at f/8 and f/11, it is, along with the Zeiss f/2 macro, the worst lens on test here when shooting with the aperture wide open at f/1.4. Similarly, the performance of the Pentax SMC DA* 55mm f/1.4 SDM isn't particularly great when wide open, with the corners and edges resolving almost the same amount of detail.
