Interesting. I'd like to see some more shots. Something with sun and bright, contrasty stuff. Wide open and heavy stopped down (~f11..16, at f22 the kit lens gets fuzzy by diffraction).
How AF acts with this adapter? Does it work at all, is it slow/hunting/erroneous?
What might be the problem in here, that you cant get completely rid of unsharpness. Even when stopping down a lot.
E.g. besides the vignetting, at the top of the second shot the books are completely smeared, and this is in a very reduced size image.
I dont know the price of adapter. Probably it has some very limited uses. I'd see it as some near range action/reportage lens where capturing feeling of the event is more important than absolute quality - as it would be with landscapes. If it's anywhere near 100$, i'd better look at zenitar 16 or something similar.
And with landscapes, in most case it's not a problem to stack multiple images for wider view.

I think some UWA's can even distort reality. I believe the door is open and you can see what's behind them.
