Originally posted by Nicolas06 Samyang lenses are more manual primes with high defect rate and calibration issues.
Do you have any numbers to support this statement?
When I read responses to Samyang lenses, I typically receive confirmation of my own impression that the lenses are optically excellent, very well built, and a steal for their price.
Actually I don't recall anyone reporting issues with a copy. I'm sure it happens, as it does with every lens manufacturer but on the basis of my observations, there is no support for the idea of a "
high defect rate“.
