You can take good pictures with just about any decent camera but having nice equipment makes the process easier, adds more options, and generally produces better results.
I started off with a fixed lens Petri 35mm film camera, then later moved to a Asahi (Pentax) Spotmatic. With both of those I was able to take nice pictures of people and scenic landscapes. I tried very little real nature photography. Neither camera was really suited to any kind of closeup work. I added a 300mm lens which helped with some types of nature shots. But it wasn't until many years later when circumstances changed and I was able to afford much better equipment and accessories. My interest in photography and the results of my efforts made a major leap forward.
Then after I got busy with so many other things (work), I slowly got rid of all that equipment.
