Mitakon Speedmaster MFT Cine Lens set opens up to T-1.0 and is light weight. Its a great lens to get started with and still produce great quality images. Best used with a follow focus and sticks, but you can held hold for relatively smooth shots on the fly.
The price is right, so if you are looking for a set that will help you with your narrative productions, you might want to look into this lens set.
