>>3364413>softer 1Kg Sigma monstrosityNigga what? Sigma's latest f/1.4 lenses are some of the finest primes you can buy, the 50 and 85 Art in particular are pretty much as good as $4k Otuses. Maybe in some cases a slower Zeiss will be a bit sharper at the same aperture when shooting test charts, but it's perfectly understandable that a lot of people would prefer the extra flexibility from +2 stops of aperture because in real life with lenses this good the sharpness is far more likely to be limited by other factors.
Also who the fuck cares whether the lens is symmetric or not.
