First solid measurements of lens variance

Quote:Good grief...

 

Dave, failure copies are pre-screened. 


A true bad copy of the 24mm f/1.4G looks something like this: https://www.dropbox.com/s/c1u239jo5bjtiw...s.pdf?dl=0


While a decent one looks more like this: https://www.dropbox.com/s/xeqnnkx2oz31qh...s.pdf?dl=0

 

If my own standards were used, not a single copy of any rokinon model would pass inspection. 

 

In my honest opinion no lens should be scored lower than 6-6.5 which indicates about +/- 5-10% but alas, this is too tight a tolerance. 

 

Keep in mind that despite the Otus' similar score to the 58/1.8G, there is this massive difference present: https://www.dropbox.com/s/sfm1gkhripnsn6...O.pdf?dl=0

  Thanks Airydiscus,

As I thought none of the lenses seemed to be excessively bad/decentered, the tests showing just variations in sharpness etc.
