The Krea 2 model is free to download and use. The AI models can be downloaded from huggingface.com. The software I'm using to run it, Forge-Neo is free and open source. It can be installed standalone, but it is easier to just install Stability Matrix first and then use that to download and manage it.
Yes you can specify lens types and f-stop to a certain extent even with the base models. For more advanced effects / lighting, etc. There are plugins called Loras, most of which are also free. There is a numbered series of Loras called Vision Vanguard that I'm trying out.
There are loras for different types of film grain, styles like Technicolor, 50s Scifi movie, etc. The best site for loras is civitai.com and most are also on huggingface.com. You can filter and search for almost anything. Those sites are also free, but require creating a free account.
As an example, here is the description for the Vision Vanguard 22 lora (most of the loras are around 218MB in size vs ~12GB for the AI models):
