Samsung NX 16mm f/2.4 test delayed - Klaus - 12-02-2011
The tested sample showed a field curvature beyond any limits that we've seen before.
I will get a 2nd sample now.

If you like I can provide my samlpe for testing.

Oh, 2h too late ...
But if you like you could provide your 50-200 at some stage. :-)

At what point is the image corrected ?. I find the geometry on the jpg the same as the raw on this lens on a NX100.
Can i view it uncorrected ?.

Field curvature has nothing to do with auto-correction nor can it be corrected anyway - this is related to a curved focus field rather than a more or less flat one. The tested sample had a focus field where the border/corner focus was extremely pulled towards you so infinity focus (actually mid field focus) was lost.
I had to stop down to f/11 to achieve a decent corner sharpness. At f/5.6 even the mid field was already bad.

It's really strange that this lens is in short supply. It seems as if dealers are extremely cautious to avoid overstocking.

Thanks, i think you will find your sample was fine. I experience this also.

That means you already replaced it with a new one?

It means that I ordered the new one 2h earlier. It's not yet here.
