To give you a rough idea of size, a 3000mm lens with a maximum aperture of f/8 built for a DSLR sensor would need to have a front lens element with a diameter of about 360mm (more than 14 inches)!” If you were to design and build a 24-3000mm DSLR lens for an FX-format sensor, you might need a truck to carry it. “Thirty years ago Nikon developed an AI Zoom-Nikkor 1200-1700mm f/5.6-8P IF-ED lens, and it weighed 16kg!
