Hello
This is a lens which has been around in one guise or another for decades. It was based on a Leica design when Minolta had a technical partnership with them.
The limitations are obvious, its a 2:1 standard zoom with a f4 max aperture. So not too inspiring at first glance. however as you say quite cheap and really good quality so I would certainly recommend it if you dont have a standard lens or need a stunt lens for the beach or sports holiday, where it might get broken.
All the best
