A big eye is always attractive to photographers.
The lens was tested in various situations and lighting condition before using this lens for my job. (A wedding day photography was the first official job for the lens, and will be posted very soon.)

I like the performance of the lens when wide open. A bit difficult to focus , but when using the EVF on my Sony A7s, it is no problem at all.
Some comparison while the aperture stopped down.
Not surprisingly, when 1 or more stops down, the images will be sharper, e.g. the fringes of the object in focus.
Vignetting for the lens is quite obvious. I tried to calibrate the the raw files (not applied in the images above) in Lightroom and found that the vignetting problem could be resolved by the around +60 or more.
Will upload some wedding day photos taken by this lens soon.
