Usually, when the lens tested by me features a long list of important assets and just one flaw, and, at the same time, it is able to reach record-breaking resolution in the test I have no doubts that I should award it our 'Editor's Choice' badge. In this case, however I decided not to do so although I admit it was very close.

Why? There are several reasons. First and foremost – this wretched distortion. I find a decision to produce a huge, flagship, expensive, optically complex lens and pass on correction geometric deformations completely weird. Especially that in previous chapters we showed clearly that it entails squandering as much as 14% of pixels of the sensor.

As if it wasn't enough, from a lens that costs $2100, a show of force of the new system, you could expect a tad better performance by f/1.4 and f/2.0 and a bit lower level of astigmatism. Not to mention focus breathing which medium level of 8% allowed it to avoid the cons list but it was also was a kind of surprise. After all we speak here about a producer that claims video recording is one of their priorities.

I wouldn't like to end this summary in a pessimistic way because the tested Panasonic definitely doesn't deserve this – after all I was very close to award it our 'Editor's Choice' badge. I am also very sure that it will stay on the podium for a very long time as a record-breaking lens, regularly mentioned in the resolution chapter concerning all L-mount models.
