Hum vignetting pretty high which (to me) suggest underdeveloped design. Pity the canon lens was never tested on a high resolution sensor.

With all the innuendo, I was expecting a surprise of the negative kind. Glad it hasn't materialized. I'm not going to switch to Sony but this lens looks good. Would've made a good combo with the 12-24/4 and the 24-70/4 if the latter hadn't sucked so much.

Are there examples of lenses that vignet less at these focal lengths on Sony mirrorless FF? If not, maybe it is more a function of the small mount diameter, rather than "underdeveloped design"?
