Image quality

Wide open:
Not crazy sharp but good enough in my book
35mm have quite a lot of corner softness which is mostly gone by f/8
Gets better when you zoom in.

Nice and sharp stopped down and renders good.

Build quality

Really good and next to all metal so it's nice and solid.
Also quite good feel to it.


Conclusion

Moderate image quality plus a nice and solid build quality.
Handels flares very good and bokeh looks farly good.

Closer focus distance would have been nice and 0.7m can be a problem at some occasions.

Quite a nice lens, especially considering what you can find this for.
