Filming

Build quality

Very good and solid.
Also have a great feel to it.


Conclusion

Really nice and sharp and image quality between f/4.5 - f/11.
But contrast is not the best and gets a really ugly light spot towards the middle that begins at f/11 but is a problem at f/16 - f/32.
So one can se it as a lens that can only stop down to f/11 or f/16 to avoid this light spot.

Flare looks great when the light comes directly into the lens but it have a problem with backlight.


Thumbs up:
Image and Build quality
Great sharpness
Bokeh
15 bladed aperure


Thumbs down:
Light spot at f/16 - f/32
Backlight
