Build quality

Really good!
Very solid and well put together.

I have owned three of these and two of them have hade sticky glue residue around the robber where you focus.
Don´t know if this is a normal problem for these lenses but it could be worth to take a extra look if you plan to get one.


Conclusion

I like this lens, its sharp and have good contrast.
But this gets a thumbs down for its corner softness that it have at all apertures.
You don´t have those soft corners on a cropped sensor camera so this is very suitable for those.

Thumbs up:
Center sharpness
Build quality

Thumbs down:
Soft corner sharpness at next to all apertures (On a full frame camera)
