So I finally picked up an FX30 for some short film work I am doing in a cramped apartment in Chicago next month and honestly I am a bit stuck on the glass. I am mostly shooting narrative stuff so I really want that shallow depth of field for the close-ups but space is a huge factor. Ive spent hours on YouTube looking at the Sigma 30mm f1.4 because everyone says it is the gold standard for budget APSC but then I see people arguing that the 56mm is the only way to get a real cinematic portrait look because of the compression.

The problem is if I go with the 56mm I feel like I will be backed up against the wall literally the whole time and still only getting a headshot. Then there is the Sony 35mm f1.8 which has stabilization but some people say the bokeh looks nervous or jittery compared to the Sigma glass. I have got about $750 saved up for this one lens and I am just trying to figure out which one is going to give me that creamy professional look without making the apartment feel like a shoebox. Should I just stick with the wider 30mm and get closer to the actor or is the compression on a longer lens actually worth the struggle in a small room?
