This Hanimex 28mm f/2.8 is not a very sought after lens, nor a very common one, but the optics are surprisingly good! It was released in many different mounts ranging from FD to Yashica/Contax (which this example is). Highly recommended if you’re just entering the awesome world of vintage lenses.
Here we have a Yashica ML 50mm f/1.9. An all metal and glass compact 50mm with a Yashica/Contax mount. Nice and fast at 1.9 and produces crisp, clear pictures. This is on of my favourites and can be picked up for relatively little money!
