SLRgear tested the Sony 35mm f/1.4 lens and wasn’t really satisfied with the image quality at f/1.4: “Sharpness performance is quite soft, and chromatic aberration is high; further, on a full-frame body, corner shading is also quite high“. But they also say that there isn’t any better alternative lens on market. You have to spend $1360 to get the lens on amazon.
My suggestions is to take a look at the Sigma 30mm f/1.4 EX DC HSM Lens (click here to see the lens on amazon). Ok it is 5mm wider but it costs $439.00 only!
