Build quality

Quite a lot of plastic parts and apparently not the best build quality.
Feel and solidness is still okay.


Conclusion

Not too bad image quality for a zoom.
Wide open do have some purple aberration and a little glow.
But nothing too bad and sharpness sill quite nice.
Plus stop it down a little and it's nice all over.
And I find it to render quite nice with mostly good bokeh etc.
Distortion at 28mm can however be quite noticeable.

Build quality is a somewhat of a let down especially compared to the other adaptall lenses have tested so far.

But these are often find quite cheap and are still a very nice zoom lens.
So you do still get a lot of lens for your money.


Thumbs up:
Image quality (mostly stopped down)
Bokeh & Flare
Value for the money


Thumbs down:
Build quality
Distortion at 28mm
