Thank you!
I have mixed feelings about this lens.
It was cheap to buy but then you get what you pay for ;)
It is good with daylight but at night, with multiple light sources, the pictures have plenty of (d)effects.
I like it vintage feel and look, I think the built quality is nice, especially for the price. Astro-photography, I haven't tried it for this, but I suspect it won't do very good at this. Still worth the try, though :)
