Ça ressemble à la mise en conformité d'une norme de sécurité imposée par l'U.E. (on était tous menacés par notre appareil photo, comme par les bouchons de bouteille apparemment)

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.
