Looking fo a great bad ass camera to take close ups with, and tips appreciated;)
Maybe a decent camera and a bad a$$ lens designed for close ups?
You could get a used DSLR at a good price now, like a Nikon D7100 or D7200, and look to get a macro lens for closeup work. Not familiar with high end point and shoots and what macro capabilities they may have. But if you get a removable lens make sure it is macro which will allow you to get close. Be advised that macro photography also requires a sturdy tripod to eliminate camera shake.
You can also use extension tubes on regular lenses which work good but then again xtra cost.
Looking at the t8i I think
Should be a good camera for you. Be sure to leave enough change for good glass, will make all the difference for good pics. Not sure if you are getting a kit lens with the body or not. Will still need a macro lens if you want real good closeups.
