personally owned the 12-24 nikkor
sigma 12-24 and sigma 10-20
currently using sigma 10-20
the nikkor 12-24 more contrast but the contrast can be enhanced with PS. so no issue
but sigma 12-24 is full frame AND it's perfect. no distortion. all lines are 100% straight. the ONLY wide angle with no distortion.
sigma 10-20 has got distortion from 10-11.5/11.7mm.
thereafter it is as straight as sigma 12-24.
the only reason why i let go sigma 12-24 is for the emergency 2 mm. but otherwise i use from 12mm onwards usually.
yes, i actually look at the lens to make sure i am at 12mm.
in terms of CA(chromatic aberation) both sigma is better than the nikkor 12-24
the ONLY reason to get nikkor 12-24 is the F4 constant.
in regards to build of sigma 12-24. it's 1 piece aluminium with built-in aluminium hood.
10-20mm is quite plastic.
