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.

But if you like you could provide your 50-200 at some stage. :-) Samsung NX 16mm f/2.4 test delayed - marschiert bunt - 12-02-2011 Damn <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/sad.gif' class='bbc_emoticon' alt='' /> I just hope it will arrive someday... still no estimated delivery date. Samsung NX 16mm f/2.4 test delayed - paulrs - 12-02-2011 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 ?. Samsung NX 16mm f/2.4 test delayed - Klaus - 12-02-2011 [quote name='paulrs' timestamp='1322821902' post='13431'] At what point is the image corrected ?.

[/quote] 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.

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