Bmpcc 4k lens choice

[Harrys Papadopoulos]

So i am trying to decide which lenses I should pair with my bmpcc 4k. I do not really like the sigma 18-35 which I have worked with in the past. My budget is around 700€. Given these circumstances i am considering the following options: 1)A 16mm and a 35mm meike lens. 2)An 8mm fisheye, a 25mm meike and a helios 44-2 3)A 24mm f2.8 canon fd, a 50mm f1.4 canon fd with a speed booster and maybe a fisheye. My issue with 1) is the small censor therefore luck of light and luck of an ultra wide, issue with 2)not a consistent cine lens pack and crop factor and 3) i am relying to much on old lenses which might come with flaws. Which one would you prefer? Do you have any other suggestions?
