Can I use the small studio to take pictures of antique vases and other still lives?

See what effect you want to shoot. Generally, a smaller studio is enough, and a still life stage is needed. If the light is on, the studio can use a flash. The camera is preferably a professional SLR. It is better to have a macro lens, and three lights are enough. (If you only shoot still life) It's about 10000. The main cameras and lenses are expensive and the lighting is very cheap. You can buy a slightly better one around 800.
