Probably commendable as the first (or at least among the first?) effort in the AF market?
I am considerng this lens for A6000 to be used by David-a 3 years old, do you think it is small enough and can tolerate some falls and bumps ? Sony 16mm is doing a good job here
I beat Rover and found a typo Big Grin
speaking about vignetting it is noted
4.65EV (f-stops) at f/2
obviously it meant f2.8 Smile

Vignetting here at f5.6 is still visible was auto correction used ?
Do you have any sky samples at f2.8 or any photos at f2.8 to evaulate vignettiing ?

I know there were some, I just wasn't in a position to read it all attentively and point 'em out. Smile
Found a couple more ;-)

The sample images were processed via PS using the activated default correction.
from photos performance seems disappointing Sigma 30mmf2.8 should be a better choice here right ?
Wasn't it discontinued some time ago? It was not available in X-mount anyway.

It's discontinued long time ago, but you still can find especially on the used market, with raw material and shipping costs raising, low profit margin gear isn't a good business anymore...
Look at Canon they used to sell tons of entry level cameras and cheap kits, now they barely give any importance to this market segment
