Have got my black paint copy few day ago. Below has some shot for reference.
In my opinion, the IQ is very similar a original one. Specially, the vignette is same as 'copy & paste' when aperture set between F2.0-F2.8.
But it has been optimized a shaperness, contrast is a little higher than original, and highlight handling is better than. Build quality is awesome, the lens is very beautiful.
I think you guys will love it after received.
PS: All film were processed in the same time and same tank.
