I've bought an used copy (rated as 'like new') of the Samyang 35mm AF F2.8 to replace my Sigma 30mm F2.8 DN | A, supposedly being the Samyang of equal or superior sharpness and at the same time lighter. After a very quick test it looks like it's decentered at the right side. It's quite obvious at ƒ/2.8, less at ƒ/4 and almost invisible at ƒ/8. It will be used for landscape, so mostly at ƒ/8.
Is it a Samyang bad copy, so should I return it, or is it the supposed quality of this kind of lens? I own the Samyang 12mm F2 manual focus, and it is slightly decentered as well.
The Sigma is not decentered and at apertures wider than ƒ/8 its borders are bit sharper. I really don't know what to do now, probably I should return the Samyang...
