You already received a lot of good advice. Let me share another angle.
For low light to very-low light photography, you need to use a fast lens: i.e., a lens with large aperture (or low f number) like f1.8 to f1.4. A fast lens let me light into the sensor and allows you to use lower ISO.
Let me share a personal experience. A few years ago, I was shooting at sunset with my K-7 with friends using Canikon. (The K-7 is well-known for good IQ at low ISO and poor IQ at ISO above 800. Simply not the best camera for low light.) When the light started to drop about 19:00, I used a fast lens (VL58mm f.14) on my K-7. My friends stopped to shoot about 19:20, the last one stopped at 19:30 although he was using an expensive Nikkon f2.8 sport lens. With my K-7, I was able to shoot until 19:50, and honestly my shots were more than decent until 19:45. The trick was the fast lens (f1.4).
There are a number of older fast Pentax lenses, some being excellent value, worth to consider.
Hope that the comment may help.
