I think, in all fairness, that could be more an issue of the a7 AF in low-light than a lens issue. For those two shots, I had to use AF because I had the camera on the ledge of a building and it was inconvenient for me to MF them. In this case, I suspect it was due to the a7 missing the focus while the E-M1 nailed it.

Thanks for the reviews - they were clear and enjoyable to read.

I think that the CZ lens doesn't perform so well. The PL looks better to me in the center, and more so on the sides (taking into account that the noise might affect the judgement somewhat). If I were you, I would have tested the CZ very seriously while I can still replace it. The following are crops from the city scape, I think that the crop from the center indicates that focus was OK.

PL vs CZ, center.

PL vs. CZ, sides.
