The resolution test of the Panasonic G Macro 30 mm f/2.8 ASPH. MEGA O.I.S. was based on RAW files from the Olympus E-PL1. In the case of that body the highest results reached by the best fixed focal length lenses amount to about 80 lpmm (the record of 82.6 lpmm belongs to the Voigtlander 0.95/25 and the Olympus 1.8/75 is not far behind). The decency level hovers around 44-45 lpmm.

Let’s glance at the graph below, presenting the results in the frame centre and on the edge, to see how the tested lens compares.

The performance in the frame centre is excellent. Already at the maximum relative aperture the MTFs reach a very high level of 72 lpmm; on stopping down to f/4.0 the lens reaches the peak of its possibilities amounting to a praiseworthy value of 76 lpmm. Still it should be noticed that it is a tad lower than the best performance of the Panaleica 2.8/45 and the Olympus 2.8/60 as both these instruments by f/4.0 were able to exceed slightly 80 lpmm.

It would be also difficult to say something bad about the edge of the frame. Already by f/2.8 the results are higher than 56 lpmm so distinctly above the decency level and then they increase to over 60 lpmm. These are values much better than those of the more expensive Panaleica and a bit better than those of the Olympus. On the edge of the frame the cheapest macro lens actually fares the best – a round of applause!

At the end of this chapter traditionally we present crops taken from photos of our resolution testing chart saved as JPEG files along with RAW files, used for the analysis above.
