Build quality

Very well made and are solid as a rock.
The feel is also very good.


Conclusion

Quite the nice lens but not exactly a perfect one.
And my biggest thumbs down is the soft corners which is visible at all apertures.
Center sharpness is however not too bad and stop it down a little and it's great.
Also a very nice bokeh and handles flares and backlight well.

Closest focus of 0.4m (1.25ft) is not all that great on a 28mm.
I personally very rarely use a wide lens closer then that but it's always nice with the option.

A lens with some dark spots but also one that can make some really nice images.
These are often find cheap and you do get quite a lot value for the money.


Thumbs up:
Center sharpness stoped down
Renders, Bokeh and flare
Build quality and feel

Thumbs down:
Soft corners
Closest focus of 0.4m (1.25ft)
