It's all about learning how to use what ya got. I can pick up an older cell phone and tweak the settings to really dial it in, and I'll still get a better pic than people just shooting straight from the newest shit. Hold on I'm on mobile gonna grab the chrome book to actually type this out.
As others said its more about the lens than the body of the camera. I just shoot with a simple lil' Canon Rebel T7 (pretty sure the same one in the pic of the link that
@BH posted) and a 100mm 2x macro lens for up close stuff, and a 50mm for shooting whole plants and stuff, that really lets you drop the aperture and have a nice depth of field that really accentuates what you're trying to shoot.
Also, I shoot like 100 pics for every 1 usable photo I end up with. On a good day.
oh yeah, that little 10 dollar trigger there is a godsend. Keeps the camera perfectly still while triggering. And yes that "tripod" is not enough for the weight of the lens haha
