"Every 35mm F1.4 DG HSM will be checked using Sigma’s own MTF measuring system, “A1,” as will all new lenses under the Global vision categories. This system uses 46-megapixel Foveon direct image sensors to pick up previously undetectable high-frequency details for quality control inspections."
I found this interesting, I wonder how much quality control they decided to step up. When the Sigma 50 came out, I went through 5 lenses before finding one worth keeping. (then ended up selling it a month later, )
