Like a painting: Luxcon MC 3.5-4.5 28-80 Macro

Cost $24.99 (average cost unknown, but probably less)

Looks again like a lens made by Kobori. I was only able to find to one other Luxcon lens, so it's not the most common brand. This 28-80mm was probably also sold by the like of Soligar, Quantaray, Sigma, Vivtar, etc... and the Vivitar version allowed to find the original manufacturer, being Kobori.  There is not much to find on Luxcon, and it was probably a smaller brand of a local camera shop.

I don't really like the look of this lens. It's shiny black, and that's not a patina I like for metal lenses, or any lens in general. It also looks like just a large tube. Working is smooth, but one the main problems is that the focus ring is huge, but the zoom ring is way to small.  It was rather clumsy to work with as I always tended to use the wrong ring.

Let's talk about quality. Nice colors, and some sharpness in the middle. But my goodness, all sharpness is gone at the edge. It almost looks like paint smudges in the corner. Thanks to the bright colors, the pictures are not a total waste, but there are so many much better lenses out there for less or equal money. 

MC stands for Multi Coated.
