>>3634223>poorfag meme lenses.I also have the Zeiss Distagon 35/2, the Planar 50/1.4, and Pentax DA* 55 1.4. They are very well corrected, magical lenses. But they don't give you the same moody look.
The Planar 50 is very hard to focus. The Pentax 55/1.4 will give you that perfect glossy look every time, so you won't learn anything by using it.
The Distagon 35/2 is a must buy if you have the money, but OP is on a budget of €500 which is the cost of this lens, give or take €100.
My go to portrait lens is the Pentax 85/1.8. Never felt the need to upgrade, just perfect.
