Just a quick look at the zoom range of the Tamron 150-600mm G2 lens with & without extenders.
1st up without any teleconverters - 600mm x 5x = 3,000mm ~ x 30x = 18,000mm
2nd up with a 1.4x Kenko teleconverter - 840mm x 5x = 4,200mm ~ x 30x = 25,200
3rd up with a 2x Kenko teleconverter - 1200mm x 5x = 6,000mm ~ x 30x = 36,000
4th up with both teleconverters - 1680 x 5x = 8400 ~ x 30x = 50,400mm

The 30x is quite terrible, but the 5x isn’t too bad.
